Our take on the Cummins P4500idf Dual Fuel Generator

The Cummins P4500idf is a dual-fuel inverter generator rated at 3,700 running watts and 4,500 peak watts on gasoline, with propane as an alternative. It runs at 52 dBA, has electric start plus a remote key fob, and rolls on 5.5-inch wheels with a telescoping handle. At $1,146.15 at Camping World as of November 3, 2026, it sits at the top of its recent price range, so there is little discount to be had right now.

Questions and answers

Is the Cummins P4500idf worth it at $1,146.15?
It is a fair price for a quiet dual-fuel inverter with remote start, but it is at the top of its recent range. If you do not need propane or remote start, a gas-only inverter costs less.
How many watts can it run on propane?
Propane output is lower than gasoline, so plan on roughly 10 to 15 percent less running wattage. Treat 3,700 watts as the gasoline figure and size your loads below that on propane.
Can it power an RV air conditioner?
A single 13,500 BTU RV air conditioner with a soft-start kit is within reach at 3,700 running watts. Two air conditioners at once are not.
Does it have a 240V outlet?
No. Outlets are one 120V 30A TT-30R, one duplex 120V 20A and two USB ports, so 240V appliances will not work.
What comes in the box?
The generator, a battery charger and a wireless key fob for remote starting. A propane hose and regulator are needed to run on LPG.
How loud is it?
Cummins rates it at 52 dBA, which is quiet enough for campgrounds that enforce noise limits. Expect it to rise under heavy load.
Where is the Cummins P4500idf Dual Fuel Generator cheapest?
At Camping World, for $1,146.15, 27% under what the other stores charge, as of our latest check.
