Frequently Asked Questions
What is the difference between a dual fuel generator and an inverter generator?
Dual fuel describes a generator that can run on two fuels, usually gasoline and propane.

The right choice depends on your load, and the largest gasoline running output listed here is 9,000W.
Smaller loads and easy transport point toward the lighter units, such as one listed at 40.3lbs.
