These are our calculations from Harbor Freight's published figures, not Harbor Freight figures.
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 5000 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.
