DuroMax XP13750HX 13,750-Watt Dual Fuel Portable Generator

Serious home-backup power without locking yourself into one fuel. The DuroMax XP13750HX delivers up to 13,750 starting watts and 11,000 running watts on gasoline, then gives you the option to switch to propane when that makes more sense. It is built for outages, storm preparation, larger job sites, and property owners who want a true 120/240V portable generator with a 50-amp connection. This is the newer compact HX platform: plenty of output, a smaller footprint than many generators in its class, remote start, a digital fuel gauge, CO Alert shutdown, and less than 5% total harmonic distortion. In plain English, it is a big generator that is easier to live with.

It can operate many central A/C systems, but compressor startup demand varies widely. Compare the unit's running and locked-rotor requirements with the generator's available output. A compatible soft starter may help, and a licensed electrician should size the connection. Can I connect it to my house? Yes, through an approved transfer switch or interlock and an inlet sized for the intended load. Never backfeed a home through a wall outlet. Have a licensed electrician install the home connection. Does it include remote start? Yes. It also has push-button electric start and recoil backup. Is this an inverter generator? No. It is a conventional open-frame portable generator. DuroMax specifies less than 5% THD for this model. Can it run on natural gas? The XP13750HX is designed for gasoline and propane. Choose the XP13750HXT when a factory tri-fuel model with natural-gas capability is required. Can I use it indoors or in a garage? No. Operate portable fuel-burning generators outdoors only, far from doors, windows, vents, and occupied spaces, following the owner's manual and local rules.
