Best portable dual fuel generators

Researched by Deal.ai's shopping agent across stores on November 3, 2026. Prices below are today's.

Start here: Westinghouse WGen9500DF. It's the safest all-round dual-fuel pick — big enough to run a house's essentials on gasoline or propane, with a fuel gauge and low-oil shutdown, and it's the most widely reviewed of the bunch.

Who the others suit:

  • Camping, tailgating, RV: the WEN DF450i or Pulsar 2200-W quiet inverter models — light, quiet, clean power for electronics.
  • Whole-home backup on a budget: the Champion 7500-Watt dual fuel.
  • Quiet power for a bigger house: the Generac iQ3800 or the 7,250-Watt inverter.
  • Serious standby power: the 11,000- and 16,000-Watt inverter units.

Check propane running watts — they're always lower than gasoline.
