The DuroMax XP13500iH Delivers 13,500 Peak Watts of Clean Dual Fuel Inverter Power

The DuroMax XP13500iH Dual Fuel Portable Inverter Generator gives you flexible, clean backup power on gasoline or propane. Its 550cc DuroMax engine produces 10,500 running and 13,500 peak watts on gasoline, or 10,000 running and 12,750 peak watts on propane, with less than 3% total harmonic distortion.

A 50A outlet for interlocks and transfer switches, remote start, CO Alert shutdown and DC output for battery banks make it a capable home backup generator. It runs at 66 dB at 25% load and is backed by a 5-year DuroMax warranty.


DuroMax XP13500iH Features

Quiet, Clean Sine Wave Power

Total harmonic distortion under 3% protects computers, TVs and appliance electronics. Demand-based variable idle matches engine speed to the load for lower noise and better fuel economy.

Dual Fuel Operation

Run on gasoline or propane. A 4-foot propane hose with regulator is included, and DuroMax suggests a 40 lb tank or larger.

Home Backup Ready

A 14-50R 50A outlet and an L14-30R 30A outlet connect to interlocks and transfer switches. Two 5-20R GFCI outlets cover everyday loads.

Remote and Push Button Start

Start with the included remote control or the push button, with a recoil starter as a backup. The AGM battery and included battery tender keep it ready.

CO Alert Shutdown

A built-in sensor shuts the generator down if carbon monoxide builds to unsafe levels around the unit.

DC Output

DuroMax lists DC output for charging 48V and 52V battery banks, and DC output wires are included.

Long Runtime

The 8-gallon tank delivers about 19.9 hours at 25% load and 10.8 hours at 50% load on gasoline. On a 40 lb propane tank, DuroMax rates about 16.9 hours at 25% load and 9.2 hours at 50% load.


Real-World Applications

Home backup. Through an interlock or transfer switch, run essential circuits and in many homes, central air.

Storm season. Switch to stored propane when gasoline is scarce.

Battery bank charging. Use the DC output to recharge compatible 48V or 52V battery systems.

RVs and job sites. Connect to 50A RV service, or run tools with stable power.


How It Compares to Common Alternatives

Versus the DuroMax XP13500iHT. The iHT adds natural gas operation and a natural gas hose.

Versus the DuroMax XP11000iH. The XP13500iH adds 1,500 running watts on gasoline and a larger 8-gallon tank.

Versus the DuroMax XP13000HX. The open-frame HX costs less. The XP13500iH runs quieter with cleaner power.


Is the XP13500iH the Right Fit

  • California. It is EPA certified but not CARB certified, so it is not available for sale in California.
  • Outlets. It has two 5-20R outlets, so plan cords for plug-in loads.
  • Weight. At 234 lbs dry, it rolls on its wheel kit.
  • Home connection. Use an interlock or transfer switch installed by a licensed electrician.

This may be a good fit if

  • You want clean dual fuel inverter power for home backup
  • You want remote start and a 50A outlet
  • You want DC output for a battery bank
