14 Best Portable Propane Generators for Backup Power in 2027

Among these portable propane generators, I’d choose the WEN DF680iX as the best overall for its combination of inverter power and dual-fuel flexibility. The Westinghouse WGen3600DFc is a stronger fit if you want a conventional generator for home backup, while the compact Pulsar PG2200BiS favors lighter-duty, portable use. The main tradeoff is between higher output and easier transport, with inverter models adding cleaner power but often less capacity than conventional units. Propane can store well for backup use, but output and runtime depend on the generator, load, and fuel supply. Read on for the full breakdown and help matching the right model to your needs.

Key Takeaways

• The WEN DF680iX is the most balanced pick in this lineup: it pairs inverter-style power with more output than the compact models, though it is not the lightest choice.
• Inverter generators and conventional generators serve different priorities. Models such as the ERAYAK 4500W and WEN DF360iX lean toward cleaner power and portability; the larger Westinghouse WGen units prioritize capacity.
• The lineup covers very different power demands. The Pulsar PG2200BiS and Westinghouse iGen2550DFc suit modest loads, while the WGen11500TFc is aimed at buyers who need substantially more output.
• Dual-fuel does not mean identical propane performance. Compare the propane wattage listed in each model’s specifications, not just the headline gasoline or peak-watt figure.
• More output brings practical costs beyond fuel. The large WGen9500DF, WGen10500DFc, and WGen11500TFc call for more storage space and more effort to move than the compact inverter options.

More Details on Our Top Picks

1. WEN DF680iX 6800-Watt Dual-Fuel Portable Inverter Generator

   

   Best Overall for Higher-Demand Backup

   View Latest Price

   I’d put the WEN DF680iX first for buyers who want propane flexibility without giving up the capacity to run several household essentials. On propane, it supplies 4,500 rated watts; gasoline raises that to 5,100, giving it more headroom than the ERAYAK 4500W inverter when loads grow. Its 120/240V outlet also suits equipment that the 120V-only Westinghouse iGen4000DFc cannot serve. Electric start, a recoil backup, wheels, and a telescoping handle make its size easier to manage, while CO shutdown adds a useful safety layer. The tradeoff is a relatively short 6.1-hour gasoline runtime at half load, and the parallel kit is separate. I’d choose it for capacity and outlet flexibility, not for the lightest carry or longest gas interval.

   Pros:

   • Provides 4,500 rated watts on propane and 5,100 rated watts on gasoline.
   • 120/240V outlet supports a broader range of backup loads than 120V-only models.
   • Electric start has a recoil starter backup.
   • CO shutdown, low-oil and low-fuel shutdown, and overload protection add safety features.

   Cons:

   • Gasoline runtime is up to 6.1 hours at half load.
   • A 240V parallel connection kit is sold separately.
   • Its higher output and wheeled format are less convenient to carry than compact models such as the 54-pound ERAYAK.

   Best for: Homeowners who want propane-capable backup for multiple essentials, including equipment that needs 120/240V output.

   Not ideal for: Campers prioritizing a light, quiet generator or buyers who need long gasoline runtime between refueling stops.

   • Engine:224cc
   • Fuel types:Gasoline and propane
   • Gasoline output:6,800 surge watts; 5,100 rated watts
   • Propane output:6,000 surge watts; 4,500 rated watts
   • Noise level:64 dB at quarter load
   • Runtime:Up to 6.1 hours on gasoline at half load; up to 9 hours on propane at half load with a 20-pound tank
   • Receptacles:L14-30R 120V/240V, two 120V three-prong, TT-30R RV, 12V DC, and two 5V USB
   • Safety features:CO shutdown, low-oil and low-fuel shutdown, and overload protection
   • Warranty:3-year limited warranty
   Our verdict

   “Choose the WEN DF680iX if you need the lineup’s strongest mix of propane output and 120/240V capability, and can accept more bulk and frequent gasoline refueling.”

2. Westinghouse WGen3600DFc Dual-Fuel Portable Generator, 4650 Peak Watts

   

   Best for RV Owners Who Want Remote Start

   View Latest Price

   The Westinghouse WGen3600DFc favors easy operation over inverter-style portability: its remote and push-button starts spare you a pull cord, and its 30A RV outlet makes it a practical match for compatible travel trailers. Its 3,240 rated propane watts are less than the WEN DF680iX delivers on propane, but they can suit an RV or a modest set of backup loads without stepping up to the WEN’s larger output class. A 4-gallon tank and stated gasoline runtime of up to 14 hours reduce fuel stops, though that runtime is not specified at a load level here. Unlike the ERAYAK and Westinghouse iGen4000DFc, this is not presented as an inverter generator, so I’d favor it for straightforward power and starting convenience rather than a compact, quiet setup for sensitive electronics. Wheel installation and battery hookup are part of setup.

   Pros:

   • Remote and push-button electric starting reduce reliance on recoil starting.
   • Includes a TT-30R 30A RV outlet.
   • Runs on gasoline or propane and can switch fuels without shutting down.
   • Four-gallon gasoline tank and stated runtime of up to 14 hours support longer operation between refills.

   Cons:

   • Provides 120V output only.
   • Wheel installation and battery hookup are required during assembly.
   • The product is not identified as an inverter generator, unlike the ERAYAK 4500W and Westinghouse iGen4000DFc.

   Best for: RV owners and homeowners seeking a dual-fuel 120V generator with remote start and a 30A RV outlet.

   Not ideal for: Buyers who need 120/240V output, inverter-style power, or a generator that arrives ready to use without wheel and battery setup.

   • Engine:212cc, 4-stroke OHV
   • Fuel types:Gasoline and propane
   • Gasoline output:3,600 rated watts; 4,650 peak watts
   • Propane output:3,240 rated watts; 4,650 peak watts
   • Fuel tank capacity:4 gallons
   • Gasoline runtime:Up to 14 hours
   • Outlets:5-20R 120V duplex, TT-30R 30A, and L5-30R 30A
   • Starting system:Electric push-button and remote start
   • Safety features:Low-oil shutdown, CO shutdown, and overload protection
   Our verdict

   “Pick the WGen3600DFc for remote-start convenience and RV-ready 120V power, but look to an inverter model if quieter operation or inverter output is your priority.”

3. ERAYAK 4500W Dual-Fuel Portable Inverter Generator

   

   Best Compact Inverter for Longer Trips

   View Latest Price

   For portable propane use where carry weight and quieter operation matter, the ERAYAK 4500W makes a different case from the wheeled WEN DF680iX: it weighs 54 pounds and is rated at 58 dBA at quarter load. Its propane peak output is 4,050 watts, but rated propane output is not supplied, so I wouldn’t choose it based on peak figures alone for sustained heavy loads. It has a 30A RV outlet alongside USB-A and USB-C, and its stated pure-sine-wave output is aimed at sensitive electronics. The listed propane runtime of over 20 hours is appealing, though the description does not give the load or tank size for that figure. Gasoline runtime is up to 16 hours at only 25% load. Compared with the Pulsar PG2200BiS, it offers a higher peak output and more ports, but it is heavier and less suited to grab-and-go use.

   Pros:

   • 54-pound weight is easier to move than larger wheeled backup generators.
   • Rated noise level is 58 dBA at 23 feet at quarter load.
   • Includes a 30A RV outlet, USB-A, and USB-C.
   • Pure-sine-wave output is specified for sensitive electronics.

   Cons:

   • Propane peak output is lower than gasoline output, and rated output is not provided.
   • The 16-hour gasoline runtime applies at just 25% load.
   • The stated propane runtime does not specify its load or tank size.

   Best for: RV travelers and outdoor users who want a relatively light dual-fuel inverter with a 30A outlet and USB-C.

   Not ideal for: Buyers sizing a generator for sustained high loads or needing confirmed rated propane watts and runtime at a clearly stated load.

   • Fuel types:Gasoline and propane
   • Peak power:4,500 W on gasoline; 4,050 W on propane
   • Voltage:120 V
   • Outlets:Two 120V/20A outlets, one 30A L5-30P RV outlet, USB-A, and USB-C
   • Gas tank capacity:2.25 gallons
   • Runtime:Up to 16 hours on gasoline at 25% load; over 20 hours on propane (load and tank size unspecified)
   • Noise level:58 dBA at 23 feet at quarter load
   • Weight:54 lbs
   • Warranty:3-year limited warranty
   Our verdict

   “Choose the ERAYAK for portable, quieter inverter power with useful RV and USB connections, but verify its sustained propane capacity against your actual loads.”

4. Westinghouse iGen4000DFc Dual Fuel Portable Inverter Generator

   

   Best for Convenient, Quiet 120V Use

   View Latest Price

   The Westinghouse iGen4000DFc suits buyers who value quiet operation and easy starting more than 240V capability. Its noise output is listed as low as 52 dBA, and remote, electric, and recoil starting give it more starting options than the recoil-only Pulsar PG2200BiS. Compared with the ERAYAK 4500W, it offers the convenience of remote start and a rotating display for fuel level, output, runtime, voltage, and lifetime hours; the ERAYAK is lighter at 54 pounds and has USB-C. The Westinghouse’s 3,300 rated watts and 4,000 peak watts can cover moderate 120V loads, with a TT-30R outlet for RV use, but it cannot provide 240V power. Its 1.69-gallon gas tank also means the stated seven-hour runtime comes with a modest reserve. This is a comfort-and-control pick, not a long-running heavy-load option.

   Pros:

   • Listed noise output is as low as 52 dBA.
   • Remote, electric, and recoil starting offer flexible operation.
   • Rotating digital display shows fuel level, output, runtime, voltage, and lifetime hours.
   • Low-distortion output is specified at less than 3% THD.

   Cons:

   • 120V-only output cannot serve loads requiring 240V.
   • The 1.69-gallon gasoline tank supports up to seven hours of runtime.
   • It weighs more than the 54-pound ERAYAK, which is designed for compact portability.

   Best for: Campers and homeowners who want quieter 120V inverter power, remote starting, and an at-a-glance operating display.

   Not ideal for: Buyers who need 120/240V output, longer gasoline intervals, or a lighter generator for frequent carrying.

   • Fuel types:Gasoline and propane
   • Power:4,000 peak watts; 3,300 rated watts
   • Voltage and frequency:120 volts; 60 hertz
   • Runtime:Up to 7 hours
   • Gas tank capacity:1.69 gallons
   • Noise output:As low as 52 dBA
   • Total harmonic distortion:Less than 3%
   • Outlets:120V duplex household outlet, TT-30R 30A RV outlet, and two USB outlets
   • Starting methods:Remote, electric, and recoil
   Our verdict

   “Choose the iGen4000DFc for quiet, feature-rich 120V use with remote start, but skip it if your backup plan requires 240V or longer fuel intervals.”

   → See it on Amazon →

5. Pulsar PG2200BiS Portable Dual-Fuel Inverter Generator

   

   Best Compact Pick for Light Loads

   View Latest Price

   The Pulsar PG2200BiS is the carry-first choice here: at 44 pounds, it is the lightest listed option and has a compact case-style design. That portability comes with a clear ceiling: it provides 1,800 rated gasoline watts, while the ERAYAK 4500W and Westinghouse iGen4000DFc have much higher stated peak outputs and 30A RV outlets. Pulsar’s 2,200 gasoline peak watts (2,000 on LPG), two 120V outlets, and USB port fit small electronics and modest campsite loads, not a broad home-backup plan. Its stable sine-wave output and parallel capability add flexibility, but parallel use requires another compatible generator. Propane operation also needs planning: the stated runtime is only 75 minutes at half load with a 1-pound LPG tank. Recoil starting and a one-year limited warranty make this a simpler, more hands-on pick than the remote-start Westinghouse models.

   Pros:

   • At 44 pounds, it is lighter than the other reviewed generators.
   • Inverter output provides a stable sine wave for sensitive electronics.
   • Parallel capability can add output when paired with a compatible unit.
   • A propane hose and basic maintenance accessories are included.

   Cons:

   • Rated gasoline output is 1,800 watts, limiting the loads it can sustain.
   • Runtime is 75 minutes at half load with a 1-pound LPG tank.
   • Recoil start and a one-year limited warranty offer less convenience and coverage than the Westinghouse iGen4000DFc.

   Best for: Solo campers and outdoor users who need a lightweight generator for small electronics and modest loads, with propane as a fuel option.

   Not ideal for: RV owners needing a 30A outlet, households seeking substantial backup capacity, or buyers expecting long runtime from a small LPG tank.

   • Fuel types:Gasoline or LPG
   • Peak output:2,200 watts on gasoline; 2,000 watts on LPG
   • Engine:80cc, 3 hp, single-cylinder, 4-stroke OHV, air-cooled
   • Fuel tank capacity:1.18 gallons
   • Runtime:Up to 8 hours on gasoline at half load; 75 minutes on a 1 lb LPG tank at half load
   • Outlets:Two 120V 15A AC outlets and one 5V USB outlet
   • Weight:44 pounds
   • Warranty:1-year limited warranty
   Our verdict

   “Choose the PG2200BiS when low carry weight and light-load propane flexibility matter more than RV-ready output or extended LPG runtime.”

   → See it on Amazon →

6. Westinghouse WGen11500TFc 14,500-Watt Tri-Fuel Portable Generator

   

   Best for Maximum Fuel Flexibility

   View Latest Price

   The WGen11500TFc stands apart from the other picks by accepting gasoline, propane, and natural gas, giving home backup buyers more ways to keep power available when one fuel is hard to get. Its 11,500 running watts and 240-volt output suit larger loads and transfer-switch connections, while the WGen9500DF is a less powerful, dual-fuel alternative. Remote and push-button starts reduce the effort of getting this large unit running, and less than 5% THD is a useful specification for electronics.

   The tradeoff is portability: a 550cc engine and 9.5-gallon tank make it cumbersome compared with the compact inverter generators in this lineup. The transfer switch itself is sold separately, and the stated 19-hour runtime applies at only 25% load on gasoline. I’d choose it for flexible, high-output backup, not frequent solo transport.

   Pros:

   • Three fuel choices offer more flexibility than the dual-fuel models in this lineup
   • 11,500 running watts and 240-volt outlets support substantial home backup loads
   • Remote and push-button electric start make startup easier
   • CO sensor, low-oil shutdown, and less than 5% THD add practical protection and power quality

   Cons:

   • Large engine and 9.5-gallon tank make it cumbersome to handle
   • Transfer switch is not included
   • The 19-hour runtime figure is at 25% load and does not describe heavier backup use

   Best for: Homeowners who need high-output backup and want the option to run on propane or a natural-gas supply as well as gasoline

   Not ideal for: Campers and buyers who need a generator they can lift or move frequently without assistance

   • Fuel types:Gasoline, propane, natural gas
   • Peak output:14,500 watts
   • Running output:11,500 watts
   • Engine:550cc 4-stroke OHV
   • Fuel tank:9.5 gallons
   • Runtime:Up to 19 hours at 25% load
   • Outlets:30A L14-30R and 50A 14-50R
   • Starting:Push-button electric start and remote start
   • Total harmonic distortion:Less than 5%
   Our verdict

   “Choose the WGen11500TFc if you need substantial backup power and three fuel options, and can accommodate a large generator.”

7. Westinghouse iGen2550DFc Dual-Fuel Portable Inverter Generator, 2,550 Peak Watts, RV-Ready 30A Outlet

   

   Best Compact RV Inverter

   View Latest Price

   At 43.2 pounds, the iGen2550DFc is the easiest fit here for buyers who prioritize a smaller, quieter generator over high output. Its 1,900 running watts are well below the WGen3600DFcv’s 3,600 running watts on gasoline, so it is better suited to modest RV and campsite loads than to powering several household circuits. The TT-30R RV outlet gives it a direct connection for compatible RV setups, while inverter output with less than 3% THD is a sensible match for sensitive electronics.

   Noise as low as 52 dBA and gasoline-or-propane operation add flexibility for campgrounds, but output and tank capacity set limits. The 1.11-gallon tank means more frequent refueling than the WGen3600DFcv’s four-gallon tank, and 1,900 running watts can constrain simultaneous appliances. Parallel capability offers a way to expand output with a compatible unit, though that adds equipment and setup.

   Pros:

   • At 43.2 pounds, it is easier to move than the larger open-frame generators here
   • Runs on gasoline or propane
   • Less than 3% THD supports sensitive electronics
   • Quiet operation, a 30A RV outlet, and parallel capability suit campsite use

   Cons:

   • 1,900 running watts limit the number and size of loads it can support
   • The 1.11-gallon gasoline tank means more frequent refueling during extended use
   • Parallel operation requires a compatible second generator and additional setup

   Best for: RV owners and campers who need a relatively light dual-fuel inverter for modest loads, electronics, and a compatible 30A RV connection

   Not ideal for: Households seeking whole-home or multiple high-draw appliance backup, or buyers who want long run intervals without refueling

   • Fuel types:Gasoline or propane
   • Peak output:2,550 watts
   • Running output:1,900 watts
   • Weight:43.2 pounds
   • Runtime:Up to 12 hours, depending on conditions
   • Fuel tank:1.11 gallons
   • Noise level:As low as 52 dBA
   • Outlets:One TT-30R 30A RV outlet, two 120V 20A outlets, two USB outlets
   • Total harmonic distortion:Less than 3%
   Our verdict

   “Pick the iGen2550DFc for quieter, lighter RV and camping power when its limited running output fits your load list.”

   → See it on Amazon →

8. Westinghouse iGen2800DFc Dual-Fuel Portable Inverter Generator

   

   Best Compact Pick for a Little More Output

   View Latest Price

   The iGen2800DFc keeps the quiet, compact inverter format of the iGen2550DFc but raises gasoline output to 2,200 running watts, making it a better fit when a small generator needs a little more headroom. Propane output drops to 1,980 running watts, so fuel choice affects what loads it can handle; buyers should size their appliances around the selected fuel. Like the iGen2550DFc, it offers less than 3% THD, a 30A RV outlet, and noise as low as 52 dBA.

   Its 45-pound weight is still manageable for many users, though it is slightly heavier than the iGen2550DFc and does not bring a major capacity increase. A recoil start is less convenient than the WGen9500DF’s remote and electric starting. Eco Mode, a fuel gauge, and an hour meter help with day-to-day operation, but the 1.1-gallon tank and 120V-only output make this a camping and small-load choice, not a substitute for the larger home-backup generators.

   Pros:

   • 2,200 gasoline running watts provide more headroom than the iGen2550DFc
   • Gasoline and propane operation gives fuel flexibility
   • Less than 3% THD and quiet operation suit electronics and campsites
   • Eco Mode, fuel gauge, and hour meter support easier monitoring

   Cons:

   • Propane running output is lower at 1,980 watts
   • Recoil starting takes more effort than electric or remote start
   • The 1.1-gallon tank and 120V-only output limit extended or larger-load use

   Best for: Campers and RV owners who want inverter power, a 30A RV outlet, and more gasoline running capacity than the iGen2550DFc provides

   Not ideal for: Buyers who need 240V output, electric or remote starting, or substantial home-backup capacity

   • Fuel types:Gasoline or propane
   • Peak output:2,800 watts gasoline; 2,520 watts propane
   • Running output:2,200 watts gasoline; 1,980 watts propane
   • Engine:98cc 4-stroke OHV
   • Weight:45 pounds
   • Runtime:Up to 12 hours at 25% load
   • Noise level:As low as 52 dBA
   • Outlets:120V TT-30R 30A and 120V 5-20R 20A duplex
   • Total harmonic distortion:Less than 3%
   Our verdict

   “Choose the iGen2800DFc over the iGen2550DFc when you want a modest gasoline output bump in a quiet, portable inverter.”

9. Westinghouse WGen9500DF Dual Fuel Portable Generator, 12,500 Peak Watts

   

   Best for High-Output Dual-Fuel Home Backup

   View Latest Price

   The WGen9500DF is the stronger fit for buyers who want high-output backup on gasoline or propane without stepping up to the tri-fuel WGen11500TFc. It delivers 9,500 running watts on gasoline and 8,500 on propane, so it can support larger loads than the WGen3600DFcv while giving up natural-gas compatibility and some output to the WGen11500TFc. A 50A outlet and L14-30R connection provide options for RV and transfer-switch setups, and remote, electric, and recoil starting offer more ways to get it running.

   The 6.6-gallon tank is smaller than the WGen11500TFc’s, with up to 12 hours of runtime listed. This is still a heavy-duty machine rather than an easy-carry camping generator; its wheels and handle are part of the transport solution, not a sign that it is light. Buyers should also plan for minimal assembly before use.

   Pros:

   • 9,500 gasoline running watts provide far more capacity than the WGen3600DFcv
   • Runs on gasoline or propane, with strong output on either fuel
   • Remote, electric, and recoil starting offer multiple startup methods
   • 50A and L14-30R outlets support varied backup and RV connections

   Cons:

   • Large, heavy-duty design requires wheels and a handle for transport
   • 6.6-gallon tank is smaller than the WGen11500TFc’s 9.5-gallon tank
   • Minimal assembly is required before use

   Best for: Homeowners who need substantial outage power, use gasoline or propane, and want transfer-switch and RV outlet options

   Not ideal for: Campers seeking a quiet, lightweight generator, or households that want natural-gas operation

   • Fuel types:Gasoline or propane
   • Peak output:12,500 watts gasoline; 11,200 watts propane
   • Running output:9,500 watts gasoline; 8,500 watts propane
   • Engine:457cc 4-stroke OHV
   • Fuel tank:6.6 gallons

10. Westinghouse WGen3600DFcv 4650-Watt Dual Fuel Portable Generator

    

    Best Mid-Range RV and Home Backup

    View Latest Price

    The WGen3600DFcv fills the gap between the low-output inverter models and the much larger WGen9500DF: its 3,600 gasoline running watts can cover a more substantial RV or outage load without the 9,500-watt generator’s heavy-duty scale. It runs on propane too, though output falls to 3,240 running watts. A TT-30R outlet makes it RV-ready, while the 4-gallon tank supports up to 14 hours on gasoline; the listed propane runtime is up to 16.5 hours with a 20-pound tank.

    Unlike the iGen2550DFc and iGen2800DFc, this is not an inverter model, so buyers focused on low noise and inverter power quality should compare those instead. In return, it offers more running capacity than either compact inverter. CO sensing, low-oil shutdown, and overload protection add useful safeguards, but its larger open-frame form is less convenient to carry than the 43- to 45-pound inverter options.

    Pros:

    • 3,600 gasoline running watts exceed the output of the compact iGen inverter models
    • Gasoline and propane operation offers useful fuel flexibility
    • TT-30R outlet supports compatible RV connections
    • CO sensor, low-oil shutdown, and overload protection are included

    Cons:

    • Propane running output is lower than gasoline output
    • Open-frame design is less portable and quiet than the iGen2550DFc and iGen2800DFc
    • 120V output does not provide a 240V connection

    Best for: RV owners and homeowners who need mid-range 120V power, propane flexibility, and a direct 30A RV connection

    Not ideal for: Buyers prioritizing a light, quiet inverter for sensitive electronics, or those needing 240V output for household circuits

    • Fuel types:Gasoline or propane
    • Peak output:4,650 watts
    • Running output:3,600 watts gasoline; 3,240 watts propane
    • Engine:212cc 4-stroke OHV
    • Fuel tank:4 gallons
    • Runtime:Up to 14 hours on gasoline; up to 16.5 hours on propane with a 20-pound tank
    • Outlets:One 5-20R 120V duplex, one TT-30R 30A RV, one L5-30R 30A
    • Safety features:CO sensor, low-oil shutdown, overload protection
    Our verdict

    “Choose the WGen3600DFcv when you need more RV or outage capacity than a compact inverter offers but do not need a large 240V backup unit.”

11. PowerSmart 3800-Watt Dual-Fuel Inverter Generator

    

    Best for Quiet, Lightweight Backup

    View Latest Price

    The PowerSmart’s appeal is its combination of propane flexibility, inverter power, and 50.7-pound weight. It supplies 3,100 running watts on propane, a useful level for keeping essentials or a modest RV setup going without stepping up to a much heavier open-frame generator. At 59 dBA at 25% load in Eco Mode, it is also quieter under that stated condition than the WEN DF360iX’s listed 65 dB at quarter load. The 24-hour propane runtime is a strong low-load figure, but it should not be read as runtime under heavy demand; gasoline operation is limited by a 1.3-gallon tank. Compared with the larger Westinghouse WGen10500DFc, this PowerSmart gives up substantial output in exchange for a more portable, quieter inverter format. Its 3,300-watt gasoline running output also makes it a poor match for buyers trying to power several large loads at once.

    Pros:

    • Runs on gasoline or propane, giving buyers a choice of readily stored backup fuel.
    • 50.7-pound weight is easier to move than the large Westinghouse WGen10500DFc.
    • Rated at 59 dBA at 25% load in Eco Mode.
    • Includes a CO sensor, overload and short-circuit protection, and household, DC, and USB outlets.

    Cons:

    • The 1.3-gallon gasoline tank limits refueling intervals.
    • Running output tops out at 3,100 watts on propane and 3,300 watts on gasoline.
    • The 24-hour propane runtime applies to the stated setup and is not a heavy-load runtime estimate.

    Best for: Campers and homeowners who want a relatively light inverter generator for electronics, modest RV loads, or essential circuits, with propane as a practical fuel option.

    Not ideal for: Buyers who need to run several high-draw appliances together or want long gasoline intervals between refills; its 3,300-watt gasoline running output and 1.3-gallon tank limit that use.

    • Fuel:Gasoline and propane
    • Starting watts:3,800 W gasoline; 3,500 W propane
    • Running watts:3,300 W gasoline; 3,100 W propane
    • Noise:59 dBA at 25% load in Eco Mode
    • Runtime:Up to 8 hours on gasoline at 25% load; up to 24 hours on a 20 lb propane tank
    • Gasoline tank:1.3 gallons
    • Engine:149 cc, 4-stroke
    • Weight:50.7 lb
    • Outlets:120V 30A L5-30R; 120V 20A 5-20R duplex; 12V 8A DC; dual 5V 2.1A USB
    Our verdict

    “Choose the PowerSmart if portability, quieter inverter operation, and extended low-load propane use matter more than high output or long gasoline runtime.”

12. WEN DF360iX Dual-Fuel Portable Inverter Generator, 3600-Watt, RV-Ready

    

    Best for RV Owners

    View Latest Price

    The WEN DF360iX is the clearest fit here for RV users who want an inverter generator with a 120V TT-30R outlet ready for an RV connection. Its 2,600 rated watts on propane are below the PowerSmart 3800’s 3,100 propane running watts, so buyers should check their appliance loads rather than choose by surge wattage alone. The WEN counters with CO shutdown, fuel shutoff, and a three-year limited warranty, plus a 49-pound listed weight that suits camping better than the much larger Westinghouse WGen10500DFc. Its listed 65 dB at quarter load is louder than the PowerSmart’s 59 dBA figure under a similar stated load condition. Runtime is another limitation: up to five hours at half load on gasoline means refills can come sooner than some buyers want. The parallel kit is sold separately if more capacity is needed.

    Pros:

    • Includes a 120V TT-30R RV outlet alongside household, DC, and USB connections.
    • Dual-fuel operation lets buyers use gasoline or propane.
    • CO shutdown sensor, low-oil and low-fuel shutdown, and overload protection are included.
    • 49-pound listed weight and a three-year limited warranty suit portable recreational use.

    Cons:

    • Propane rated output is 2,600 watts, below the PowerSmart 3800’s 3,100 watts.
    • Gasoline runtime is up to five hours at half load.
    • Parallel connection kit is sold separately.

    Best for: RV owners and campers who need a 120V TT-30R connection, clean inverter power for electronics, and the option to run on propane.

    Not ideal for: Households needing higher propane running output or extended gasoline operation; the rated output is 2,600 watts on propane and gasoline runtime is up to five hours at half load.

13. Westinghouse WGen10500DFc Dual Fuel Portable Generator, 13,500 Peak Watts

    

    Best for Whole-Home Backup Capacity

    View Latest Price

    The WGen10500DFc occupies a different class from the inverter models in this group: its 10,500 running watts and 240V output are aimed at larger backup loads, not quiet campsite use. That capacity far exceeds the PowerSmart 3800 and WEN DF360iX, making this the choice for buyers who need to operate more household equipment at once. Remote key-fob and push-button starting reduce the effort of getting it running, with recoil as a backup. It can run on gasoline or propane, though the supplied runtime figure—up to 19 hours—applies at only 25% load and does not describe heavy backup use. Wheels and a handle help with repositioning, but a 500cc engine and large output class are not compact-generator conveniences. Buyers should also account for the separate transfer switch or interlock equipment needed for a home connection.

    Pros:

    • 10,500 running watts and 240V output support larger backup loads than the inverter models here.
    • Runs on gasoline or propane.
    • Offers push-button, remote key-fob, and recoil starting.
    • Wheels and a handle support moving the generator, and the listed runtime reaches 19 hours at 25% load.

    Cons:

    • The 19-hour runtime figure is specified at 25% load, not at full backup demand.
    • A transfer switch or interlock setup is not included.
    • Its high-output, 500cc format is a poor fit for buyers seeking compact or quiet portable power.

    Best for: Homeowners with substantial backup loads who need 240V capability, high running wattage, and electric or remote starting.

    Not ideal for: Campers, noise-sensitive users, or anyone prioritizing a small, light generator; this high-output model is much larger in purpose and capacity than the inverter options.

    • Fuel:Gasoline and propane
    • Peak output:13,500 W
    • Running output:10,500 W
    • Engine:500cc, 4-stroke OHV
    • Fuel tank:9.5 gallons
    • Runtime:Up to 19 hours at 25% load
    • Voltage:240 V
    • Starting:Push-button electric, remote key fob, and recoil
    • Safety:CO sensor and automatic low-oil shutdown
    Our verdict

    “Choose the WGen10500DFc when high-capacity 240V home backup matters more than the compact size and inverter format of the smaller picks.”

14. Westinghouse 6500-Watt Dual-Fuel Portable Generator with CO Sensor

    

    Best Midrange Choice for RV and Home Backup

    View Latest Price

    This Westinghouse is a practical middle ground between the compact inverter generators and the high-output WGen10500DFc. Its 5,300 gasoline running watts and 4,800 propane running watts offer a meaningful step up from the PowerSmart 3800, while remaining a less extreme choice than a 10,500-watt model. The TT-30R and L14-30R outlets serve RV and transfer-switch-ready uses, and the package includes a wheel kit and propane hose, reducing the number of basics buyers need to source separately. A 4.7-gallon tank is listed for up to 14.5 hours of runtime, though the supplied data does not specify the load for that figure. Unlike the PowerSmart and WEN inverter picks, this is not presented as an inverter generator, so buyers who prioritize inverter-style power for sensitive electronics should compare that distinction before choosing. Some assembly is required.

    Pros:

    • Provides 5,300 running watts on gasoline and 4,800 on propane.
    • Includes RV-ready TT-30R and transfer-switch-ready L14-30R outlets.
    • CO sensor, automatic low-oil shutdown, and overload protection are listed.
    • Wheel kit, propane hose, oil, funnel, and tool kit are included.

    Cons:

    • Requires some assembly before operation.
    • Its listed runtime does not include a load condition, making comparison with load-specific figures difficult.
    • Lacks the inverter format specified for the PowerSmart 3800 and WEN DF360iX.

    Best for: RV owners and homeowners who need more output than a compact inverter can provide, plus 30A connections and included propane accessories.

    Not ideal for: Buyers who need a lightweight camping generator or specifically want inverter power for sensitive electronics; this model is a larger conventional-generator option.

    • Fuel:Gasoline and propane
    • Running watts:5,300 W gasoline; 4,800 W propane
    • Peak watts:6,500 W gasoline; 5,800 W propane
    • Engine:274 cc, 4-stroke OHV
    • Fuel tank:4.7 gallons
    • Runtime:Up to 14.5 hours
    • Voltage:120/240 V
    • Outlets:5–20R 120V duplex; TT-30R 30A; L14-30R 30A
    • Safety:CO sensor with automatic shutdown; low-oil shutdown; overload protection
    Our verdict

    “Choose this Westinghouse for midrange home or RV output and included setup accessories, but look to an inverter model if sensitive-electronics power is your priority.”

How We Picked

I compared the 14 generators around the decisions that matter for portable propane use: propane output, generator type, fuel flexibility, portability, and intended workload. I separated inverter models from conventional open-frame units because their strengths differ: buyers may favor inverter designs for sensitive electronics and easier transport, while conventional models can provide more capacity for home backup. I also looked at whether each product’s stated wattage and outlets align with common uses such as RV support, essential circuits, or heavier loads.

The ranking favors useful balance over the biggest headline number. Models that combine practical output with a clear use case rank ahead of options that make sense only for a narrow need; compact picks remain valuable for buyers who put weight and footprint first. I also treated the published propane rating as more relevant than peak wattage alone and accounted for tradeoffs such as size, fuel flexibility, and the limits of what a portable unit can power. Since specifications and included accessories can vary by model or listing, verify the exact product configuration before buying.

Factors to Consider When Choosing Portable Propane Generators

Choosing a propane generator is less about finding the highest wattage and more about matching the machine to the loads, location, and handling you can live with. I’d work through these factors before choosing between a compact inverter and a larger conventional model.

Size the generator around starting loads

Write down the appliances or equipment you expect to run at the same time, then check both their running watts and their startup demands. Motors in refrigerators, pumps, and air conditioners may briefly draw more power when they start, so a generator that appears adequate by running watts can still struggle with a combined load. Use the propane-specific running and peak ratings for your estimate; a prominent gasoline wattage figure may not describe propane output. For home backup, decide which essential circuits matter rather than assuming one portable unit will run an entire house. Leave headroom for startup surges and for adding a small device later. If your calculations land near a model’s limit, stepping up in capacity may be more useful than relying on ideal conditions.

Choose inverter or conventional output for the job

Inverter generators are often a better match when you value a smaller footprint, lower operating noise, or power suited to sensitive electronics. Conventional generators in this roundup focus more on delivering higher output for demanding backup loads. Neither design automatically makes the other wrong: a compact inverter can be the sensible choice for camping and modest RV needs, while a larger open-frame unit can serve tools or several household essentials. Check the manufacturer’s guidance for electronics rather than treating “inverter” as a substitute for reading the specifications. Also compare weight and dimensions, because a portable label does not mean one person can easily move every model. Match the design to how and where you’ll use it, not just to a single feature.

Compare propane output, not just dual-fuel labels

Dual-fuel capability gives you the option to use propane or gasoline, but the available output and runtime can differ by fuel. Before buying, locate the manufacturer’s propane running-watt rating and use it when planning your load. Check which fuel the generator is configured to use at startup and whether the changeover procedure fits your comfort level. Propane is convenient to store for backup when you already keep compatible cylinders, but the cylinder size and supply arrangement affect how long you can run. Don’t assume that owning a propane generator guarantees unlimited fuel during an extended outage. Think through how many cylinders you can store safely and how you would obtain more.

Plan for safe placement and connection

Portable generators produce carbon monoxide, so they must operate outdoors and away from doors, windows, and vents, following the maker’s placement instructions. A built-in CO sensor is an added safety feature, not permission to run a generator indoors, in a garage, or near an occupied opening. For home circuits, use a properly installed transfer switch or another code-compliant connection method; never feed power into a household outlet. Check the outlet types and amperage against the equipment you intend to connect, including any RV connection needs. Extension cords must be rated for the load and outdoor conditions. Planning these details before an outage is safer than improvising during one.

Balance portability against usable capacity

Portability includes more than whether a generator has wheels: total weight, handles, storage footprint, and how often you need to move it all matter. A high-output model may be useful for home backup but awkward to transport to a campsite or job site. Conversely, a lighter unit may be easy to store yet unable to start the equipment you care about most. Measure the storage area and check the product’s listed weight before deciding that a larger generator is manageable. Consider whether the route from storage to operating position includes stairs, uneven ground, or a vehicle lift. The right compromise is the biggest model you can safely handle and realistically maintain.

Think beyond the purchase to upkeep and runtime

Propane storage can reduce some fuel-storage concerns, but it does not make a generator maintenance-free. Follow the manual for oil checks, service intervals, exercise runs, and fuel-system care, and verify that required maintenance supplies are available. Runtime varies with load, fuel supply, and operating conditions, so avoid treating a published runtime as a guarantee for your household’s use. Check whether the generator’s controls and starting method are practical for the people who may need to operate it. Also plan where the unit will sit during operation and how you’ll protect it from weather without restricting ventilation. A modest maintenance routine and realistic fuel plan can matter as much as headline wattage during a long outage.

Frequently Asked Questions

How much generator output do I need to run an RV air conditioner on propane?

Start with the air conditioner’s running watts and its startup surge, then add the loads you expect to run at the same time. Compare that total with the generator’s published propane-specific output, not its gasoline rating or peak figure alone. An RV-ready outlet can simplify the connection, but it does not mean the generator can start every air conditioner or support all onboard appliances together. Check the RV and appliance manuals for electrical requirements, and account for other loads such as a microwave or battery charger. If the available information leaves little headroom, plan to stagger appliance use or choose a higher-capacity model.

Can a dual-fuel generator run on propane alone during an outage?

Many dual-fuel models can operate on propane without gasoline, but confirm the exact starting and fuel-selection instructions in the model’s manual. Propane-only operation still depends on having a compatible, adequately supplied cylinder and a working connection. The generator’s output on propane may be lower than its gasoline output, so check that rating against your planned loads. If you expect a long outage, estimate fuel needs at the load you will actually run rather than relying on a maximum runtime claim. Keep the fuel supply and connection equipment stored and handled according to the manufacturer’s directions.

Should I choose an inverter generator or a larger conventional generator for home backup?

Choose based on the circuits and equipment you want to support, not the generator type alone. Inverter models in this roundup generally suit buyers prioritizing portability and power for smaller loads, while larger conventional models target greater capacity for demanding backup tasks. If you need to start a well pump, central equipment, or several appliances at once, calculate startup and running loads before deciding. If your plan centers on a refrigerator, lights, and electronics, a smaller inverter may be easier to handle, provided its propane output is adequate. For connection to household circuits, have a qualified professional advise on a compliant transfer setup.

Is a built-in carbon monoxide sensor enough to make generator placement safe?

No. A CO sensor can add a layer of protection, but it does not replace outdoor operation and the placement distances specified by the manufacturer and local safety guidance. Never run a portable generator inside a home, garage, shed, or other enclosed or partly enclosed space. Keep exhaust directed away from doors, windows, and vents, and use working carbon monoxide alarms in occupied areas. A sensor may not prevent every dangerous exposure, especially if wind shifts or exhaust reaches an opening. Treat safe location and ventilation as requirements regardless of the generator’s safety features.

When does it make sense to pay for a higher-output portable propane generator?

Paying for more capacity makes sense when your load calculation shows that essential appliances cannot start or run together on a smaller model, or when you need room for future equipment. It may also help if you want to avoid carefully staggering every load during an outage. But a larger generator can be heavier, take up more storage space, and require a more deliberate moving and setup plan. Compare its propane rating with your actual needs before paying for a high peak-watt figure that you may never use. If portability and modest loads matter more, a compact inverter can be the better fit even with less total output.

Conclusion

Best overall: I’d start with the WEN DF680iX for a balanced mix of inverter design, dual-fuel flexibility, and useful capacity. Best value-minded choice: compare the Westinghouse WGen3600DFc and PowerSmart 3800W against your load and portability needs; the better fit depends on the exact propane output and features in the listing. Best premium capacity: the Westinghouse WGen11500TFc is the lineup’s high-output direction for buyers with larger backup demands, while its size makes it a poor match for casual transport. Best for beginners: I’d favor a manageable inverter model such as the WEN DF360iX if its propane rating covers the planned essentials, since a smaller load plan is easier to operate. For compact RV or light-duty use, look at the Pulsar PG2200BiS or Westinghouse iGen2550DFc; for heavier home backup, compare the larger WGen models and verify propane output, connections, and safe transfer arrangements before choosing.
