Champion Power Equipment's 4500-Watt Dual Fuel Open Frame Inverter Generator with CO Shield is perfect for camping, tailgating, RV use, or backup power. Quiet Technology reduces noise, & the compact design lowers weight and size. The 224cc engine provides 4500 starting watts & 3650 running watts on gasoline, running up to 22 hours at 25% load on a full 4.02-gallon tank. On propane, it offers 4500 starting watts & 3285 running watts, running 21 hours at 25% load on a 20-lb tank. A 6-foot propane hose with regulator is included. Covered outlets include a 120V 30A RV (TT-30R), a 120V 20A (5-20R) duplex, & a 12V DC outlet. With an optional Parallel Kit (sold separately), connect two inverters for more output. The Quick Touch Panel gives fast access to controls. Intelligauge with Power Meter monitors voltage, frequency, & hours. Economy Mode extends run time and improves efficiency. CO Shield technology monitors the accumulation of carbon monoxide, 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.
