Product Overview

4500 Generator Cummins P4500iDF A068H732

The dual fuel digital inverter portable, Onan 4500 Watt Generator P4500iDF with Remote Start makes just 52 dBA noise—quiet enough to have a normal conversation just a few feet away. The 3.4-gallon fuel tank keeps the generator running for 12.5 hours at a 25% load. Use regular unleaded gasoline with 10% (or less) Ethanol. A 20lb standard propane tank (4.6 gal) keeps the generator running for 15 hrs at a 25% load.

Dual fuel with just the flip of a switch. Easily switch from gas to propane with a fuel capacity of 3.4 gal. Use the Remote Fob from your RV or the Push Button for easy, trouble free startup of the 7.4 horsepower OHV 4-stroke engine. The P4500iDF rolls over most terrain with heavy duty wheels and a telescoping handle. At 104.7 pounds, it weighs less than many competing inverter generators of equal power.
