Our take on the XP15000HXT

The Duromax XP15000HXT is a large tri-fuel home backup generator that runs on gasoline, propane or natural gas. Its 670cc EFI engine and 15,000 peak watts on gasoline make it one of the strongest portable units in its class, and clean copper windings keep total harmonic distortion under 5% so sensitive electronics run safely. It suits homeowners wiring it to a transfer switch for whole-house backup, not campers or tailgaters. Rivals like the Champion 100519 and Westinghouse WGen12000TFc offer similar tri-fuel output but generally lack EFI and low-THD windings, and the Duromax is heavier and louder than smaller portables.

Questions and answers

Can it power a whole house?
Yes, with a transfer switch or inlet box. Running watts are 12,000 on gasoline, 11,400 on propane and 10,260 on natural gas, enough for most homes if large loads like electric heat are managed.

The generator, AGM battery, wheel kit, handles and a propane hose. A transfer switch and cord are not included.
