Remember when you had clean and quiet portable power? The WEN 4800-Watt Inverter Generator provides clean energy, free of voltage spikes and drops, without all the noise of a regular generator. Produce up to 4800 surge watts and 4000 rated watts of power on gasoline, or connect a propane tank using the tool-free quick-connector for up to 4320 surge watts and 3600 rated watts of power on LPG. The keyless electric start lets you turn on your generator at the press of a button, and includes a recoil starter as backup. 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 224cc engine operates at a modest 62 decibels at quarter load. This limits its invasiveness while camping, hunting, tailgating, and restoring backup power. The WEN 4800W Inverter Generator is also equipped with fuel shutoff. This feature turns off the flow of fuel, allowing for 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 to run laptops, cellphones, monitors, tablets and other sensitive electronics. The built-in wheels and telescoping handle make for easy portability while the ultra-efficient 1.9-gallon tank provides up to 7 hours of half-load run time (or 20 hours half-load run time on a 20-pound LPG tank).
