A cost-effective solution that delivers power and peace of mind, this generator will provide all the backup power you need for power outages and emergencies. For projects, the 459cc Champion single-cylinder OHV engine has what it takes to handle a multitude of power tools and large equipment you need to get the job done. Champion has convenience covered. Starting and stopping your generator from up to 80 feet away with the wireless remote key fob is a snap. No matter what you're powering, you'll enjoy the on/off push-button power with electric start, battery included. The fuel select dial allows you to safely select gasoline, propane (LPG), or natural gas (NG) as your fuel source. Using gasoline, the 459cc Champion engine produces 11,000 starting watts and 9000 running watts, and will run for 15 hours at 25% load when the 6.08-gallon fuel tank is full. When using a 20-pound propane tank with included 6-foot propane hose assembly, it produces 11,000 starting watts and 8100 running watts, and will run for 8 hours at 25% load. 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 regulated automotive-style outlet. The Intelligauge with Power Meter monitors voltage, frequency and operating hours with ease, while Economy Mode monitors power consumption in real time to reduce engine wear. As the electrical load is reduced, the inverter reduces engine speed, providing quieter operation, extended engine life and higher fuel economy. This generator is EPA certified.

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.
