Product Summary

COMPACT, LIGHTWEIGHT DESIGN - From the easy-to-carry P2500i to the highly maneuverable P9500df, Cummins Onan® portable generators deliver power to go. QUIET AND DURABLE - Double insulation means exceptionally quiet operation, and proven four-stroke overhead valve (OHV) engines deliver durable, dependable performance. FUEL EFFICIENT - Runs 10-18 hours in continuous operation (at 25% load factor) on a single tank of gasoline, while a 20-pound propane tank delivers eight hours of continuous power at 25% load. EASY STARTING - Push button and remote start capabilities, with pull cord backup, make startup as easy as the push of a button. ESSENTIAL DATA DISPLAY - From power output and fuel level to remaining run time and lifetime run time, our digital displays give you critical facts at a glance. PARALLEL CAPABLE - P2500i and P4500i inverter models can be paralleled with comparable units to provide more power to power more. ELECTRONICS COMPATIBILITY - Low total harmonic distortion values provide the clean power needed to operate sensitive electronics. MULTIPLE OUTPUTS - Inverters have both AC and DC capabilities, including USB ports. All outlets are covered to prevent dust contamination. OVERLOAD PROTECTION - Circuit breakers are easily accessible for rapid reset.
