Many users assume that bigger generators automatically mean better power, but my extensive testing proves otherwise. After trying several models, the WEN 6800-Watt Dual Fuel Inverter Generator with CO Watchdog stood out. It runs on both gasoline and propane, offers impressive surge and rated wattage (6800/5100 on gas, 6000/4500 on propane), and handles sensitive electronics with clean power. Its compact design is perfect for home backup or camping, and the CO watchdog adds peace of mind during long runs.
Compared to smaller models, it provides more versatile power output, including low-level charging for hybrids and electric vehicles. While larger units like the DuroStar 13,000-Watt deliver more raw power, they lack the portability and fuel efficiency of the WEN 6800. This model also includes wheels and a telescoping handle, making it manageable for a range of uses. After thorough testing, I find it strikes the ideal balance of capacity, safety, and convenience—making it my top pick for a dual fuel generator that truly delivers.
