The Cummins Onan P4500i Inverter Generator is a portable gasoline-powered inverter generator designed to provide reliable power for RVs, campers, outdoor events, tailgating, job sites, and recreational applications. Delivering 4,500 peak watts, the unit features a 7.3 HP 224cc OHV 4-stroke engine and includes remote start capability with onboard push-button and pull-cord backup starting options. Its inverter technology helps provide stable power for sensitive electronics, while the onboard LED display allows users to monitor runtime, fuel level, voltage, power output, and lifetime operating hours.
Built for portability and extended operation, the Onan P4500i features a 3.4-gallon fuel tank that can provide up to 18 hours of runtime at 25% load. The double-insulated enclosure helps reduce operating noise to as low as 52 dBA, making it suitable for campgrounds and other noise-sensitive environments. Integrated wheels and a telescoping handle simplify transportation, while multiple AC outlets and USB ports provide flexible connectivity for powering tools, appliances, RV equipment, and personal devices.
Designed for convenient power on the go.
