Rated 5 out of 5 by from Love this generator Bought this because I was looking for a 4,500 watt peak unit. Started up the first time I pushed the button/. We boondock a couple of times a year and in August the capacity to run our AC unit is a must. It can run our 13,500 btu AC unit and our microwave at the same time.. 15 hours at half load was the tipping point, along with a 3 year warranty. I was concerned about lifting the 100 lb generator set into my pickup. A pair of simple ramps solved that problem. Love the electric & remote start. PS: It looks like Westinghouse has a clone of this unit using a Westinghouse engine..

Rated 1 out of 5 by from Poor quality! It Doesn’t run smoothly. I just bought this generator 1 day ago and so far I have no reasons to be happy with my purchase. I’ve had 2 other generators from different brands that were used a lot without any problems. You can tell they used cheap materials on the construction and the finish looks terrible, even cheaper generators have better plastic quality. On top of it you can add the fact that this unit is louder than you’d expect and the engine revs up so high at any small load applied to the generator. I’ve never seen such thing like this before. Very disappointed. I’m a full time RVer and the generator is my main source of electricity.

Rated 1 out of 5 by from Garbage out of the box DO NOT BUY! Unboxed the generator this morning and already deeply regretting my purchase. Setup while simple is a hassle if you're a man with larger hands. I have a couple small cuts on my knuckles from the sharp edges of the plastic case where I had to reach in to install the battery and perform the initial oil fill. Once that was done did a quick 2 gallon gas fill to break in the engine and low and behold gas is leaking profusely out the bottom of the generator! If you're wondering no I didn't spill any fuel during the fill. Out of the box the unit is garbage. I shouldn't have to immediately call for service and or refund after paying over $1k. If the unit is this bad right off the line I have zero confidence in the rest of the build.

Rated 3 out of 5 by from Unit--needs Repair. Camping World disappointing Started right up after very simple prep. But, ran slow/rich. Discovered manual choke was engaged. Returned it to the run position and generator ran great...until I tried to start it the next day and discovered the autochoke feature does not work. I called Cummins hoping there was an easy fix--they told me to take it to a service center. I called Camping World to request a return. They took all my info and said I should receive the shipping mail soon by email--after 3 days I decided to take the unit to a Cummins service center--2 hours away. I have not received it back yet, but hoping it will work as advertised. It does appear to be a good unit with quality construction. I hooked it up to my RV and was able to run 2 AC units with it (75% load according to the display n the unit).

Rated 5 out of 5 by from Everything I hoped for, half the price of a Honda Very quiet, plenty of power for my AC unit. Light enough to easily load into a truck bed. Granted, I use a ramp but with two people, a ramp isn't needed. Starts easily every time. I think Honda might be in trouble with this one unless they cut their prices in half!

Rated 1 out of 5 by from Westinghouse rebranded generator, steer clear! First P4500 generator, had a sticky exhaust valve. Returned for another unit, another sticky exhaust valve, and the alternator rattled when I had anything plugged in to generator. Oil drain plug is offset from opening in case, so you can’t put a socket straight on it, have to use a combo wrench and tiny turns, good luck if you drop oil drain bolt and washer inside. I had to take all side panels off to fish bolt and washer out. I had high hopes, but very disappointed. Cummins partnered with Westinghouse, so it’s not a true Cummins. Cummins wanted to get into the inverter generator market without spending money on the R&D to make their own. Shame. Bought from Cummins direct.

I don't see a way to purchase the extended contract online. Is this option limited to purchases in the store? Also, does the extended warranty start when the manufacturers warranty ends?

I previously bought a Chinese generator and it is crap and no reputable service company will touch them. How is your generator any different?

Asked by: Diego
Used for 7 days in a row at the race track in extremely hot weather, using air conditioning, tv, plus a few other electronic items and had no issues. 7 years again we had a Chinese made generator and went through 3 of them before buying a Honda generator at that time.

Can this be used to jump-start a dead car battery?

This generator cannot jump a dead battery directly, but you can use this generator to power a battery charger or something like that.
