The WEN Super-Quiet 3,800 Watt Inverter Generator produces clean energy free of voltage spikes and drops. Generate up to 3800 surge watts and 3400 rated watts of power. Our 212cc 4-stroke air-cooled OHV engine operates at an extremely quiet 57 decibels at quarter load, about as quiet as a window air conditioner or the average conversation. The WEN 3800W Inverter Generator is also equipped with fuel shutoff. This turns off the flow of fuel, allowing the generator to use up the remaining fuel from the carburetor before automatically shutting down to prevent unwanted buildup. Designed to mirror a pure sine wave, this generator limits total harmonic distortion to under 0.3 percent at no load and under 1.2 percent at full load, making it safe enough to run laptops, cellphones, monitors, tablets and other vulnerable electronics. The lightweight design along with the built-in wheels and folding handle make for easy portability while the ultra-efficient 2.2-gallon tank provides over 8.5 hours of half-load run time. Our fully-packed panel comes equipped with two 3-prong 120V standard household receptacles, one AC 120V 30A NEMA TT-30R twist lock receptacle, one 12V DC receptacle, one 5V USB port and an easy-to-read digital fuel and load display. Maximize fuel economy by engaging the Eco-Mode switch. Easily link up two WEN inverter generators using a WEN 56421 Parallel Connection Kit (sold separately) in order to share wattage between multiple units. Backed by a two-year warranty.
