Best dual fuel inverter generators
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: WEN DF480iX. It's the best all-round dual-fuel inverter here — around 4,000 running watts on gas (about 3,600 on propane), quiet inverter output safe for electronics, and it's sold at several stores, so you have real choice on price and support. Good for a small home backup setup or RV use.
Who the others suit:
- PowerSmart 3800W (HB5040DC): tightest budget, still dual fuel with CO alert and long gas runtime — fine for a fridge, lights and a few devices.
- BILT HARD 5500W: more headroom for a well pump or window AC without jumping to a big unit.
- Pulsar 5000W RV Ready: remote start and CO Sentry make it the easiest for RV and tailgating duty.
- Cummins P4500iDF: if you want a known engine brand and remote start over lowest cost.
- Westinghouse iGen11000DFc / GENMAX GM7250iEDC: whole-home-leaning power; only worth it if you're wiring a transfer switch.
Skip the iGen12000DFc if dual fuel matters — it's gas only.
