Using gasoline, the 459cc Champion engine produces 11,000 starting watts and 9,000 running watts, and will run for 15 hours at 25% load when the 6.08-gallon fuel tank is full. It produces 11,000 starting watts and 8,100 running watts, and will run for 8 hours at 25% load when using a 20-pound propane tank. Also included is a 6.5-foot propane hose with a built-in regulator. Designed with a low oil shut-off switch, this unit has a 1.2-quart oil capacity (recommended 10W-30). Confidently connect your sensitive electronics since this inverter produces Clean Power (less than 3% THD). All the outlets have covers to protect them from moisture and dirt and include two 120V 20A GFCI protected duplex household outlets (5-20R), a 120/240V 30A locking outlet (L14-30R), a 120/240V 37.5A outlet (14-50R), and a 12V automotive-style outlet.

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.Included: Engine Oil, Oil Funnel, Allen wrench / Phillips screwdriver, Propane (LPG) Hose, Spark Plug Wrench, Battery & Wheel Kit
