The WEN 4000-Watt Dual Fuel Inverter Generator produces clean energy free of voltage spikes and drops without 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 up to 3200 surge watts and 2900 running watts of power on LPG. The WEN Watchdog CO Shutdown Sensor helps protect both you and your family by automatically turning off the generator if dangerous levels of carbon monoxide are detected. 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 backup power. Our unique Auto Fuel Selection Technology automatically switches between propane and gasoline for longer run times with limited hassle. The keyless electric start lets you turn on your generator at the press of a button, and includes a recoil pull starter as backup. The WEN 4000-Watt 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. 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.
