Generate up to 4500 surge watts and 3500 rated watts of power. Our 212cc 4-stroke air-cooled OHV engine operates at an extremely quiet 58 decibels at quarter load, about as quiet as a window air conditioner or the average conversation. This limits its invasiveness while hunting, camping, tailgating and restoring back-up power. The WEN 4500-Watt Inverter Generator is equipped with fuel shutoff, allowing the generator to use up the remaining fuel from the carburetor before automatically shutting down. Designed to mirror a pure sine wave, this generator limits total harmonic distortion to under 0.3% at no load and under 1.2% at full load. The lightweight design along with the built-in wheels and folding handle makes for easy portability while the ultra-efficient 2.2 Gal. tank provides up to 8.5-hours of half-load run time. Our fully-packed panel comes equipped with two 3-prong 120-Volt standard household receptacles, one RV-ready AC 120-Volt 30 Amp NEMA TT-30R receptacle, one 12-Volt DC receptacle, two 5-Volt USB ports and a digital fuel and load display. Maximize fuel economy by engaging the Eco-Mode switch. Link up 2 WEN inverter generators using a WEN Parallel Connection Kit (sold separately) in order to share wattage between multiple units. Low-oil and low-fuel automatic shutdown, indication lights, and overload protection safeguard both your generator and your electronics from damage. The included spark arrestor allows for legal use in national parks and campgrounds.
