Predator 11500 published runtime
- Gasoline: 14 hours at 25% load on 6.8 gallons
- Propane (LP): 14.5 hours at 25% load on a 40 lb propane tank; 36.2 hours at 25% load on a 100 lb propane tank
- Natural gas: no runtime limit published — runs as long as the gas supply continues
Harbor Freight tested propane on two tank sizes. They are kept separate: a 40 lb tank uses the 40 lb figure and a 100 lb tank the 100 lb figure. On natural gas, runtime depends on a continued gas supply; no runtime limit is published.

Which model this page covers

Manufacturer figures vs. our estimates
Only the runtimes listed above are Harbor Freight's own published figures. When your load and fuel amount exactly match one of them, the calculator labels the result Manufacturer Published Runtime. Loads between published figures are labeled Estimated from Manufacturer Data, and loads outside the published range are labeled Extrapolated with a wider range. Those are GeneratorRuntime estimates, not Harbor Freight specifications.
Operate it safely
Like every portable generator, the Predator 11500 must be operated according to the manufacturer's safety instructions: outdoors only, well away from doors, windows, and vents, with battery CO alarms inside your home. A CO shutoff feature is not a substitute for safe placement. Never refuel while the engine is running or hot.
