The Champion Power Equipment 201110 9200-Watt Portable Generator is designed with your safety and convenience in mind. 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. Generators must ALWAYS be used outdoors. Meets the requirements of ANSI/PGMA G300-2018. The convenient electric start includes a battery, plus Cold Start Technology ensures a quick start in cold weather. Designed for safety with convenient resettable circuit breakers, a low oil shut-off switch plus an included oil funnel for easy changes, 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. Covered outlets include a 120/240V 30A locking outlet (L14-30R), a 120/240V 50A outlet (14-50R), and four 120V 20A GFCI household outlets (5-20R).
