DuroMax XP11000iH Inverter Generator vs Generac iQ3800 Dual Fuel Inverter Generator

The DuroMax XP11000iH is a whole-home backup machine: about 9,000 running watts on gasoline, a 50A outlet for a transfer switch or interlock, and parallel capability. The Generac iQ3800 is a portable 3,000-watt unit for camping, tailgates and small jobsites, with a 13-hour run time at half load and a 107 lb frame. Both deliver under 3% THD for sensitive electronics and both have CO shutdown. Owners of the Generac call it quiet and easy to start; the DuroMax is the step up only if you need to run a house, not a campsite.

• Choose the DuroMax XP11000iH if you need to power a whole home or a large transfer-switch setup and want dual fuel plus parallel capability.
• Choose the Generac iQ3800 if you want a portable, quiet inverter for camping, tailgating or small jobsite loads that one person can move.
