The WEN 4000 Watt Dual Fuel Inverter Generator produces clean energy free of voltage spikes and drops without making all of the noise of a regular generator. Generate up to 4000 surge watts and 3200 rated watts of power on gasoline, or connect a propane tank for 3200 surge watts and 2900 running watts of power on LPG. 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. Our unique Auto Fuel Selection Technology automatically switches from propane to gasoline for longer run times with limited hassle. The WEN 4000W Inverter Generator is also equipped with fuel shutoff. This feature turns off the flow of fuel, allowing the generator to use up the remaining fuel from the carburetor before automatically shutting down. This helps fight the build-up and blockages caused by stagnant fuel inside of the carburetor, minimizing maintenance while prolonging the unit’s lifespan. 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.
