The Champion Power Equipment 201110 9200-Watt Portable Generator with CO Shield. For projects, the 459cc Champion single-cylinder OHV engine has what it takes to handle the multiple power tools and large equipment you need to get the job done. This unit has a 1.2-quart oil capacity (recommended 10W-30). At 11500 starting watts and 9200 running watts, this unit can handle it all in an outage - lights, refrigerator, modem/router, security system, window AC, furnace blower, TV, computer, phone charger and more. All the outlets have covers for protection and include a 120/240V 30A locking outlet (L14-30R), a 120/240V 38A outlet (14-50R), and four 120V 20A GFCI household outlets (5-20R). Fill up the 7.7-gallon tank of gasoline, and enjoy up to 10 hours of power at 50% load. From 23 feet, the noise level is 74 dBA, a bit louder than a vacuum cleaner. 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.
