DuroMax XP13000HXT
The DuroMax XP13000HXT is a portable generator rated at 8.5 kW on natural gas, 9.5 kW on propane and 10.5 kW on gasoline (continuous output, not surge). On natural gas it gives up 1 kW versus propane, a 11% derate, so if natural gas is your fuel, size against the 8.5 kW figure, not the headline 9.5 kW. Full compiled specifications, fuel burn, and pricing are in the table below; the figures come from the source page linked at the bottom of this page.

Consumption figures are manufacturer-reported values, exactly as published by the source below; propane figures for some brands are published in cubic feet per hour with the gallon-per-hour equivalent in parentheses. A figure shown as “Not in our database yet” means the source does not publish a comparable value. We leave it blank rather than estimate it.
How its price stacks up
At $1,499 for 9.5 kW on propane, this model works out to about $158 per kW. The median portable in our database is about $136 per kW (propane rating), so this one prices about 16% above the class median.
That is the generator alone, before installation. Standby installs add a transfer switch, pad, gas and electrical work, and permits; the cost guide breaks those down. Prices move; treat the figure as a compiled street price from October 2026, not a quote.
Will it run your house?
On propane, this model is rated at 9.5 kW continuous. Whether that is enough depends on what has to start at the same time: a well pump or central air conditioner can draw several times its running watts for a few seconds. Run your own appliance list through the sizing calculator, then see this model highlighted against your number in the model database: highlighted rows clear your requirement with the calculator’s 20% headroom included.
