Enjoy clean and quiet portable power with the WEN inverter generator. It produces up to 3,800 watts of surge and 3,400 watts of rated power without surges or voltage drops. The 212cc air-cooled, 4-stroke, 4-cycle engine runs on gasoline, generating 57dB at quarter load. Equipped with a fuel cutoff feature that allows the generator to use the remaining fuel from the carburetor before automatically shutting off. This minimizes maintenance and extends the life of the unit. It also produces clean electricity, preventing damage to sensitive electronics such as smartphones, tablets and laptops. The lightweight design with built-in wheels and folding handle provide comfortable portability, and the efficient 2.2-gallon tank supports more than 8.5 hours of operation at half load.
