Predator 13000W Tri-Fuel
The Predator 13000W Tri-Fuel is a portable generator rated at 7.8 kW on natural gas, 9.1 kW on propane and 10 kW on gasoline (continuous output, not surge). On natural gas it gives up 1.3 kW versus propane, a 14% derate, so if natural gas is your fuel, size against the 7.8 kW figure, not the headline 9.1 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 $1,199 for 9.1 kW on propane, this model works out to about $132 per kW. The median portable in our database is about $136 per kW (propane rating), so this one prices about 3% below 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 9.1 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.
