The WEN 2800-Watt Inverter Generator provides clean energy, free of voltage spikes and drops, without all the noise of a regular generator. Produce up to 2800 surge watts and 2250 rated watts of power on gasoline, or connect a propane tank for up to 2800 surge watts and 2000 rated watts of power on LPG. The WEN Watchdog CO Shutdown Sensor automatically turns off the generator if dangerous levels of carbon monoxide are detected. Our 98cc engine operates at a quiet 60 decibels at no load. Fuel shutoff 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 the blockages caused by stagnant fuel inside of the carburetor. Designed to mirror a pure sine wave, this generator limits THD to under 0.3 % at no load and under 1.2 percent at full load, making it safe to run sensitive electronics. The lightweight 45 lb. design makes for easy portability while the ultra-efficient 1.58 gal. tank provides up to 9 hours of half-load run time (13.9 hours half-load run time on a 20 lb. LPG tank). The fully-packed panel comes with two 3-prong 120-Volt NEMA 5-20R receptacles, one 12-Volt DC receptacle, and two 5-Volt USB ports. Maximize fuel economy by engaging the eco-mode switch. This allows the generator's engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel, preventing the unnecessary usage of fuel. Backed by a 3-year limited warranty.
