The Champion Power Equipment 4500-Watt Inverter Generator 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. 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 no tool access panel and oil drain tube allow for easy maintenance. Confidently connect your sensitive electronics since this inverter produces Clean Power (less than 3% THD). Operate your Dual-Fuel generator right out of the box on gasoline or propane, and easily switch fuels with the EZ Start dial. When the 2.3-gallon tank of gasoline is full, the 212cc Champion engine produces 4500 starting watts and 3500 running watts and will run for up to 14 hours at 25% load. When using a 20-pound propane tank, it produces 4500 starting watts and 3150 running watts and will run for up to 21 hours at 25% load. The covered outlets in this RV Ready inverter include a 120V 30A RV (TT-30R), two 120V 20A household outlets (5-20R), and dual USB outlets (5V DC, 2.1A). The optional Parallel Kit (sold separately), with included standard 50-amp RV outlet, allows you to increase output by connecting up to two 3500-watt or higher inverters. The never flat tires and fold-down handle make transport a cinch.
