DuroMax XP5500HX Dual Fuel Generator vs Champion 3500-Watt Inverter Generator

Buy the DuroMax XP5500HX if you need 240V output, a transfer-switch connection or propane backup for a house. Buy the Champion 3500-Watt Inverter if you want quieter, cleaner power for an RV, a tailgate or sensitive electronics. The DuroMax makes more power and runs on two fuels, but it is a conventional generator: heavier, louder at load and less clean on the sine wave. The Champion is lighter, quieter and inverter-based, but it is 120V only and gasoline only, so it cannot feed a home panel. Owners of both rate CO shutdown and electric start highly; the DuroMax's 4.3 rating reflects solid value, while Champion's inverter line has a long reputation for quiet RV power.

• Choose the DuroMax XP5500HX if you want 240V and a 30A L14-30R outlet for a transfer switch, plus propane as a backup fuel.
• Choose the Champion 3500-Watt Inverter if you need quiet, clean power for an RV or electronics and do not need 240V.
