The Champion Power Equipment 3500-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, the reliable 122cc Champion engine produces 3500 starting watts and 2300 running watts, and runs for 10 hours at 25% load when the 1.2-gallon fuel tank is full. With a 0.4-quart oil capacity (included 10W-30) and a low oil shut-off sensor, this inverter operates at an ultra-quiet 58 dBA from 23 feet, which is about as loud as normal speech. Refueling in the dark is a cinch thanks to the Fuel Fill Assist LED, plus the no tool access panel allows for easy maintenance. Confidently connect your sensitive electronics since this inverter produces Clean Power (less than 3% THD).
