The Champion Power Equipment 4000-Watt Portable Inverter Generator (Model 201511) is a lightweight, dual-fuel generator ideal for camping, tailgating, RV use, and home backup power. Weighing less than 55 pounds, it is one of the lightest 4000-watt inverters in the industry.

The Dual Fuel feature allows the 149cc Champion 4-stroke engine to run on either gasoline or propane right out of the box. On a full 1.54-gallon gasoline tank, it delivers 4000 starting watts and 3300 running watts with up to 10 hours of run time at 25% load. With a 20-lb propane tank, it delivers 4000 starting watts and 2970 running watts with up to 25 hours of run time. The EZ Start Dial and push-button electric start (battery included) make startup simple, and Cold Start Technology ensures reliable starts in cold weather.

Outlets include a 120V 27.5A TT-30R (RV-ready), a 120V 20A duplex household outlet (5-20R), and a 12V automotive-style DC outlet. Clean inverter power (less than 3% THD) safely powers sensitive electronics. Economy Mode automatically adjusts engine speed to match the load, reducing noise and fuel consumption. The unit operates at 64 dBA from 23 feet. An optional Parallel Kit (sold separately) allows connection to another compatible Champion inverter or power station for doubled output.

CO Shield technology continuously monitors carbon monoxide accumulation and automatically shuts off the engine if unsafe CO levels are detected. A low oil shut-off sensor protects the engine. The generator is EPA certified and PGMA G300-2023 compliant. Dimensions are 17.9 x 11.7 x 19.7 inches. Includes engine oil (10W-30), propane hose, oil funnel, and battery. Backed by a 3-year limited warranty with free lifetime technical support.
