Buying Guide for 2026
Power Output: Peak vs. Rated Watts
Peak (surge) watts handle startup loads from motors in appliances like refrigerators or air conditioners, while rated (running) watts keep them going. For example, the Westinghouse iGen5000DF delivers 5000 peak watts and 3900 rated watts on gasoline. If your RV air conditioner draws 2000 running watts and your microwave adds 1000, you still have 900 watts of headroom for lights and a fan, but the surge from the AC startup could briefly hit 3000 watts, well within the peak capacity. Always match the rated wattage to your continuous load and the peak to your largest motor startup.
For more on sizing, check our guide to 5000-watt dual fuel generators.
Fuel Type and Runtime
Dual-fuel generators let you switch between gasoline and propane. Propane burns cleaner and stores indefinitely, but reduces peak output by about 10-15%. On the Westinghouse iGen5000DF, a 3.4-gallon gas tank provides up to 18 hours of runtime at 25% load in economy mode. Propane runtime depends on tank size (not included). The maXpeedingrods MXR4000GT offers 4000 peak watts on gas and 3600 on propane, with a similar runtime profile. Choose gasoline for maximum power and longer runtimes from a single fill, or propane for emergency backup where fuel storage is safer.
Noise Level and Portability
Inverter generators are significantly quieter than conventional models. The Westinghouse iGen5000DF operates as low as 52 dBA, roughly the level of a normal conversation. The maXpeedingrods MXR4000GT is rated at 58-60 dBA in eco mode from 23 feet. For campground use, anything under 60 dBA is generally acceptable. Both Westinghouse models include a telescoping handle and never-flat wheels for easy transport, while the maXpeedingrods is lighter at around 60 pounds.

Frequently Asked Questions
Can I run my RV air conditioner on a 4500-watt dual fuel inverter generator?
Yes, most RV air conditioners draw 1500-2000 running watts with a startup surge around 3000 watts. A 4500-watt peak generator like the Westinghouse iGen5000DF can handle this, provided you manage other loads. Check your AC’s startup specs and leave headroom.
How long will a dual fuel generator run on a 20-pound propane tank?
Runtime varies by load. At 50% load, a 20-pound tank (about 4.7 gallons of propane) typically lasts 4-6 hours on a 4000-watt generator. For longer runtime, use gasoline or a larger propane tank. Always refer to the manufacturer’s specifications for your specific model.
Is it safe to use a dual fuel generator indoors?
No. Generators produce carbon monoxide (CO) and must only be used outdoors in well-ventilated areas, at least 20 feet from doors, windows, and vents. Models with a CO sensor, like the Westinghouse iGen5000DFc, add an extra layer of safety but do not make indoor use safe.
For more safety tips, see our guide to portable dual fuel generators for home.
What is the difference between a dual fuel and a tri fuel generator?
Dual fuel runs on gasoline and propane; tri fuel adds natural gas. Tri fuel models are often larger and more expensive, but offer a permanent fuel line option for home standby. Dual fuel is more portable and flexible for camping and job sites. See our tri fuel category for more.
