"Put the ultraquiet Champion Power Equipment 5500W Inverter with CO Shield to work powering your life on the go or as a backup supply in an emergency. Ideal for camping or tailgating, this 5500-watt inverter's advanced technology features CO Shield carbon monoxide auto shutoff system. If CO Shield detects unsafe elevated levels of CO gas, it automatically shuts off the engine for added safety. Featuring a .6-quart oil capacity (included 10W-30) and a low-oil shut-off sensor, this inverter operates at just 61 dBA from 23', a similar noise level to normal speech. The reliable 224cc Champion engine with Cold Start technology produces 5,500 starting watts and 4,000 running watts and runs for 20 hours at 25% load when the 3.7-gallon fuel tank is full. EZ Start Dial makes startup quick and easy. Rely on the Fuel Fill Assist LED, a flip-up LED to illuminate the gasoline fill area, to refuel in the dark. Quick Touch Panel offers fast access to your controls, plus the built-in LED lights increase visibility in low light. Intelligauge monitors voltage, frequency, and operating hours 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. The no-tool access panel and oil drain tube simplify maintenance. Covered outlets include a 120V 30A TT-30R outlet, two 120V 20A household duplex outlets (5-20R), and a 12V regulated automotive-style outlet. Add the optional parallel kit (not included) to connect another parallel-ready Champion inverter or power station for more power and longer run time. Never-flat tires and telescoping handle for easy transport. Champion Power Equipment 5500W Inverter includes engine oil, 10mm socket, and oil funnel. For outdoor use only.
