Pull power from three different sources with the WEN 13,000-Watt Tri-Fuel Inverter Generator. Simply select your preferred method - gasoline, propane, or natural gas. Generate 13000 surge and 10500 running watts on gasoline, 11250 surge and 9000 running watts on LPG, and 10000 surge and 8000 running watts on NG. Electric start powers up the generator with the press of a switch with a recoil starter as backup. CO Watchdog protects your family by automatically turning off the generator if dangerous levels of carbon monoxide are detected. Our 550cc engine operates at 64 decibels at quarter load. Fuel shutoff stops the flow of fuel before automatically shutting the unit down. This fights blockages caused by stagnant fuel inside of the carburetor. 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 panel comes equipped with one 120V/240V NEMA 14-50R receptacle, two three-prong 120V NEMA 5-20R receptacles, one 120V NEMA 10-50R receptacle, one 120V NEMA L5-30R receptacle, one 12V DC receptacle, a voltage selector switch, and two 5V USB ports, as well as side-mounted lights for better visibility in low-light conditions. The bonded-neutral 240V output supports Level 2 EV charging for off-grid peace of mind. NG hose sold separately (part no. TF1450X-1431). Backed by a three-year warranty.
