Cummins Onan Dual-Fuel Inverter Generator P4500i
The Cummins Onan portable generators are designed to go where you do. Quiet, lightweight, and equipped with long run times, these portable generators offer you the chance to power your adventures. Whether you are going camping, planning a tailgate party, or powering a jobsite, Cummins Onan has a solution for you. Cummins generators are backed by an industry leading warranty and nearly 100 years of Cummins expertise powering lives from backing up hospitals and data centers to powering trucks, boats and RVs. Cummins – powering your life.
Despite its impressive output, the P4500i remains easy to move thanks to integrated wheels and a telescoping handle. At just under 100 lbs., it’s designed to go where traditional generators can’t — without sacrificing performance.
The P4500i is powered by a durable 224cc 4-stroke OHV engine and features electric start with remote key fob convenience, plus a recoil backup for added reliability. A fully enclosed, double-insulated housing helps keep operating noise low, while the onboard LED display provides real-time system information at a glance.
With inverter technology delivering clean power at less than 3% total harmonic distortion, the P4500i is safe for sensitive electronics like laptops, phones, and tablets — making it ideal for both recreation and emergency backup.
