This Champion Power Equipment Dual Fuel Generator runs on gasoline or propane to deliver up to 2500 Watts of ultra-quiet power — just 53dB. The fuel selector dial allows for easily switching between fuels. This ultralight model makes portability and provides plenty of clean electricity for safely operating sensitive electronics. The parallel-ready design allows connection to another Champion 2500 Watt inverter to double your power output (requires parallel kit, not included). Plus, it features an Economy Mode to monitor the electrical load to reduce engine speed, noise and fuel consumption.
