How to choose

Sizing

For an RV with one roof AC, aim for 3,000 running watts or more on propane. For essential home backup, 4,500 to 9,000 W models make sense.

Weight and wheels

Dual fuel inverters above 3,000 W often weigh 80 to 120 lb: check for wheels and a telescoping handle.

Mistakes to avoid

  • Forgetting the propane derating when sizing for an RV air conditioner.

Frequently asked questions

What is a dual fuel inverter generator?

An inverter generator that can run on gasoline or propane. It combines clean power and quiet operation with the long storage life of propane.

Is a dual fuel inverter good for an RV?

Yes, especially with a TT-30R outlet: it runs on the RV's propane supply and stays quiet at the campground.

Are dual fuel inverters more expensive?

Yes, they cost more per watt than open-frame dual fuel models, in exchange for clean power, less noise and better fuel economy.
