XP13000HXT Runtime Calculator

Verified Specs ✓

Estimate how long a XP13000HXT will run based on your power load and available fuel, using DuroMax's published specifications as the baseline.

Specifications checked against DuroMax-published information. GeneratorRuntime.com has not tested this generator and is not affiliated with DuroMax.

How long does a XP13000HXT run?

DuroMax publishes:

  • 17 hours at 25% load · gasoline, 8.3 gallons
  • 8.5 hours at 50% load · gasoline, 8.3 gallons
  • 13 hours at 25% load · propane (lp), propane amount not stated
  • 6.5 hours at 50% load · propane (lp), propane amount not stated

Actual runtime varies with load and operating conditions.

XP13000HXT published runtime

  • Gasoline: 17 hours at 25% load on 8.3 gallons; 8.5 hours at 50% load on 8.3 gallons
  • Propane (LP): 13 hours at 25% load on an unstated amount of propane; 6.5 hours at 50% load on an unstated amount of propane
  • Natural gas: no runtime limit published — runs as long as the gas supply continues

DuroMax does not say how much propane its propane runtimes were measured on (it suggests a 40 lb tank minimum), so the calculator shows the published propane hours but does not estimate other tank sizes. On natural gas, runtime depends on a continued gas supply at 6–9 inches of water column; DuroMax lists 225,000 BTU per hour at full load.

Which model this page covers

This page covers the tri-fuel XP13000HXT only — not the XP13000HX or XP13000EH. Figures come only from DuroMax's current XP13000HXT page.

Manufacturer figures vs. our estimates

Only the runtimes listed above are DuroMax'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 DuroMax specifications.

Operate it safely

Like every portable generator, the XP13000HXT 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.
