What the numbers mean
- At 9,500 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: 8 h at 50% load on the 8.3-gallon tank — roughly 12.8 h at 25% load (estimated) .
- Estimated fuel cost for 24 h at ~50% load: about $80 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 XP12000EH Dual Fuel run during an outage?
With 9,500 running watts on its best fuel, the DuroMax XP12000EH 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 XP12000EH Dual Fuel run on a tank of gas?
About 8 hours at 50% load on its 8.3-gallon tank, per the manufacturer's rating. At a lighter 25% load, figure roughly 12.8 hours (estimated — fuel burn does not scale linearly with load).
What does the DuroMax XP12000EH Dual Fuel cost to run for a day?
Roughly $80 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.
What inlet does the DuroMax XP12000EH 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.
