Can the XP13500iH power a whole house?

Yes, with 10,500 running watts on gasoline it can carry a typical home's essentials through a 50A transfer switch or interlock kit. Large loads like central AC and electric heat may still need load management.

How much power does it make on propane?

Propane gives 12,750 peak and 10,000 running watts, about 500 watts less running output than gasoline. Plan loads around the propane figure if that is your main fuel.

It is an inverter generator, so it runs quieter and cleaner than a standard open-frame unit, but DuroMax does not publish a decibel rating here. Expect noticeable engine noise under heavy load.

What comes in the box?

The generator, a remote control, a battery tender, DC output wires, a 4 ft propane hose and regulator, and an oil funnel. You supply the oil and fuel.

Is the price a good one?

The best new price is $2,698.82 at Outbound Power as of November 5, 2026, with three stores listing it new. Compare against those listings before buying.

Can it charge a home battery?

Yes. The DC output is designed to charge 48V and 52V battery banks such as a Tesla Powerwall.

About the DuroMax XP13500iH 13,500 Watt Portable Dual Fuel Inverter Generator

The DuroMax XP13500iH is a 13,500-watt portable dual fuel inverter generator engineered to deliver serious power with remarkably quiet, clean sine wave output.

Backed by a 5-year warranty and USA-based support, the XP13500iH is ready to keep your home running when you need it most.
