The Champion Power Equipment 100592 6250-Watt Dual Fuel Portable Generator with CO Shield technology is designed to provide peace of mind and versatile power. Operate your Dual-Fuel generator on gasoline or propane, and switch between fuels with our patented fuel selector switch. Using gasoline, the 389cc Champion engine produces 7850 starting watts and 6250 running watts, and will run for 10 hours at 50% load when the 6-gallon fuel tank is full. When using a 20-pound propane tank, it produces 7050 starting watts and 5600 running watts, and will run for 6.5 hours at 50% load. With a noise level of 74 dBA from 23 feet, and includes 10W-30 engine oil, a 3.3-foot propane hose, a foldaway handle, and a wheel kit. Covered outlets include one 120/240V 30A locking outlet (L14-30R) and four 120V 20A GFCI protected household outlets (5-20R). CO Shield technology monitors the accumulation of carbon monoxide (CO), a poisonous gas produced by engine exhaust when the generator is running. If CO Shield detects unsafe elevated levels of CO gas, it automatically shuts off the engine. CO Shield is not a substitute for an indoor carbon monoxide alarm or for safe operation. DO NOT allow engine exhaust fumes to enter a confined area through windows, doors, vents or other openings. Generators must ALWAYS be used outdoors, far away from occupied buildings with engine exhaust pointed away from people and buildings. Meets the requirements of ANSI/PGMA G300-2018.
