The Champion Power Equipment 201417 11,000-Watt Dual Fuel Portable Inverter Generator with CO Shield® is designed with your safety and convenience in mind. 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. Operate your Dual-Fuel generator right out of the box on gasoline or propane, and easily switch fuels with our patented fuel select dial that allows for safe switching between fuel sources. The foldaway easy-grip handle and included wheel kit with never-flat tires make it a cinch to move your power where you need it. 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. 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. Buy with confidence - Champion Support and our nationwide network of service centers will back your purchase up with a 3-year limited warranty and FREE lifetime technical support. 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.
