Our take on the DuroMax XP11000iH 11,000 Watt Portable Dual Fuel Inverter Generator - Quiet, Low THD

The DuroMax XP11000iH is a dual-fuel portable inverter generator rated at 9,000 running and 11,000 peak watts on gasoline, dropping to 8,550 running and 10,450 peak on propane. Its inverter delivers under 3% total harmonic distortion, so it can run sensitive electronics, and a 50A 14-50R outlet plus a 30A twist-lock and four GFCI household outlets make it a genuine home-backup unit. It is quieter than most open-frame generators at around 61 dB at a quarter load, with remote and push-button start and a CO shutdown sensor. It sits at the high end of portable inverter power: bigger and heavier than the 7,000 to 8,000 watt class, but with dual fuel and whole-home outlets those rivals often lack.

Best forWhole-home backup through a transfer switch or interlockRV and off-grid use with a 50A hookupRunning sensitive electronics and appliancesOwners who want gasoline or propane flexibility

  • CO Alert shuts the unit down if carbon monoxide builds up
Cons
  • Heavy and bulky; not a one-person lift
  • Propane cuts output by roughly 5%
  • Parallel kit and second unit sold separately
  • Short included generator cord, about 18 inches tip to tip
