Our take on the DuroMax XP13500iH Dual Fuel 10500W/13500W Portable Inverter Generator

The DuroMax XP13500iH is a large portable inverter generator that runs on gasoline or propane. On gasoline it delivers 10,500 running watts and 13,500 peak watts; on propane, 10,000 running and 12,750 peak watts. Total harmonic distortion stays under 3%, so it is safe for sensitive electronics, and a 50A outlet plus 30A and GFCI outlets make it a serious home backup unit. It is heavy and loud at full load, but the clean power, dual fuel flexibility and remote start set it apart from smaller inverter rivals.

About the DuroMax XP13500iH Dual Fuel 10500W/13500W Portable Inverter Generator

The DuroMax XP13500iH is a portable dual fuel inverter generator that runs on gasoline or propane. Its 550cc DuroMax engine produces 10,500 running watts and 13,500 peak watts on gasoline, or 10,000 running watts and 12,750 peak watts on propane. Total harmonic distortion is under 3%, which protects computers, TVs and appliance electronics.

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. It also has DC output for charging 48V and 52V battery banks. Demand-based variable idle matches engine speed to the load for lower noise and better fuel economy.

You can start it with the included remote control or the push button, with a recoil starter as a backup. An AGM battery and included battery tender keep it ready. A built-in CO Alert sensor shuts the generator down if carbon monoxide builds to unsafe levels. It rolls on a wheel kit. Connect it to a home through an interlock or transfer switch installed by a licensed electrician.

Questions and answers

How much power does it make on propane versus gasoline?
Gasoline gives 10,500 running and 13,500 peak watts. Propane gives 10,000 running and 12,750 peak watts, slightly less because of the fuel.
Can it power a house through a transfer switch?
Yes. The 14-50R 50A outlet connects to an interlock or transfer switch, and the L14-30R 30A outlet covers smaller setups. A licensed electrician should install the connection.
Is the power clean enough for computers and TVs?
Yes. Total harmonic distortion is under 3%, which is safe for computers, TVs and appliance electronics.
How loud is it?
DuroMax rates it at 66 dB at 25% load. Variable idle drops engine speed at light loads, but it is louder than small inverter generators.
What propane tank does it need?
A 4-foot hose and regulator are included, and DuroMax suggests a 40 lb tank or larger for sustained running.
How do you start it?
Use the included remote, the push button, or the recoil starter as a backup. An AGM battery and battery tender keep it ready.
