What the numbers mean
- At 12,000 running watts on its best fuel, this unit covers most household circuits through an appropriately sized transfer switch; central air conditioning typically needs load management or a soft starter.
- Runs on gasoline, propane — expect lower output on propane (roughly 10%) and natural gas (roughly 20%) than on gasoline; the spec table shows the published per-fuel ratings.
- Runtime: 12 h at 50% load on the 13.2-gallon tank — roughly 19.2 h at 25% load (estimated) .
- Estimated fuel cost for 24 h at ~50% load: about $84 on gasoline at national average prices (assumptions).
- House hookup: pairs with a 50 A generator inlet ( 14-50 / CS6365) and a transfer switch or interlock installed by an electrician.

Frequently asked questions
What can the DuroMax XP15000HX Dual Fuel run during an outage?
With 12,000 running watts on its best fuel, the DuroMax XP15000HX Dual Fuel covers most household circuits through an appropriately sized transfer switch; central air conditioning typically needs load management or a soft starter. Add up your actual loads with a sizing worksheet — the bands here are rough guidance, not a load calculation.
How long does the DuroMax XP15000HX Dual Fuel run on a tank of gas?
About 12 hours at 50% load on its 13.2-gallon tank, per the manufacturer's rating. At a lighter 25% load, figure roughly 19.2 hours (estimated — fuel burn does not scale linearly with load).
What does the DuroMax XP15000HX Dual Fuel cost to run for a day?
Roughly $84 for 24 hours of continuous operation at about 50% load on gasoline, at national average fuel prices. The assumptions behind this estimate are documented on the methodology page; your fuel price and load change the figure.
Does the DuroMax XP15000HX Dual Fuel have a CO safety shutoff?
Yes — the DuroMax XP15000HX Dual Fuel has a built-in carbon monoxide sensor that shuts the engine down when CO accumulates around the unit. It is a backstop, not a substitute for running the generator outdoors at least 20 feet from the house.
What inlet does the DuroMax XP15000HX Dual Fuel need to power a house?
A 50 A generator inlet (a 14-50 or CS6365 connection) wired to a transfer switch or interlock kit — an electrician's job that normally requires a permit. Never backfeed through a dryer or wall outlet.
