Champion's 3000 watt inverter generator is one of the lightest in the industry at only 21.5kg, making portable power easier than ever. Rely on the 149cc engine with a quiet 58 dBA for up to 11.5 hours of run time on petrol (based on 25% load). The Parallel Kit (sold separately) can increase your output. 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.
