The Champion Power Equipment 4500-Watt Inverter Generator with CO Shield® is ultra-quiet and ideal for camping, tailgating, powering items around the RV or providing backup for your essentials. Champion’s EZ Start Dial makes getting started quick and easy. Featuring Cold Start Technology, Extended Run Time, and an easy to read fuel gauge, the reliable 212cc Champion engine produces 4500 starting watts and 3500 running watts, and runs for 14 hours at 25% load when the 2.3-gallon fuel tank is full. With a 0.5-quart oil capacity (included 10W-30) and a low oil shut-off sensor, this inverter operates at an ultra-quiet 61 dBA from 23 feet, which is about as loud as normal speech.

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 and tear. The covered outlets included are a 120V 29.2A RV outlet (TT-30R), a 120V 20A household duplex outlet (5-20R), and a 12V automotive-style outlet. Buy this EPA certified inverter generator with confidence – Champion Support and our nationwide network of service centers will back up your purchase 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.
