Champion Power Equipment 4000-Watt Dual Fuel RV Ready Portable Inverter Generator with Quiet Technology and CO Shield

Timing for purchasing this generator couldn't have been better. Living in northern lower Michigan we recently endured a severe ice storm event. I wanted a dual fuel generator for emergencies though never expected the one we had. I used only propane, and used up most of one 20# tank using it (not continuously) for the three plus days we were without electricity. The entire town's electrical grid went down, and there were no gas stations open to buy gas had I needed to. I had bought and filled a new propane tank when I got the generator and had another and a spare for the grill so I was set for a longer outage, that fortunately wasn't the case. After the initial five hours run time, I drained the oil and filled with full synthetic oil as per instructions. It worked as expected and ran much quieter than I thought it would. Still, I didn't run it overnight and running it only during the day it kept the refrigerator cold until power was restored. Overall I am very happy with my Champion dual fuel generator choice.

Got this for my camper because it had the large 240 plug! Generator is Smaller and quieter than expected! I use this for my camper and if I am running ac or anything large the generator ramps up and can be mildly loud however for most devices it’s running at idle and very quiet. I put it behind my camper and from my other side I can barely hear it running in very rural private land. Heavy but not too heavy! Starts up great for now! Just like any motor it’s about how you take care of it! Check that oil!

Love it! Runs everything I need. Use the propane feature so I don’t have gas sloshing around while I carry it and I don’t have to pour gas into a hot generator. Runs for a looong time on a 20 lb cylinder. We ran the coffee pot, waffle iron, roasting oven and hot water heating wand. Only complaint is I cannot pull the rope fast enough to start it. I kind of wish I had spend the extra and been able to start it on my own.

Great generator and easy to use. Lighting up the lift and put into my RV when traveling.

This is suppose to be RV ready but the only thing that makes it RV ready is the plug. This unit has a floating ground which is not compatible with most RV electrical systems and surge protection systems which will give you a "no ground" fault. After discussing with a Champion Tech over the phone, I was told that I would have to buy a "ground to neutral" adaptor plug. YouTube videos addressing this issue will tell you to purchase or make a 110 plug adaptor which has a grounded neutral. They say all you have to do is plug it into the 110V outlet of the generator and this fixes the issue. Not on this generator because the 110V 20A circuit (standard receptacle) is isolated from the 30A RV ready receptacle so it is useless for the 30A grounded neutral on that circuit. I thought it would be easy to find an adaptor since I figured everyone with a later model RV would have the same issue. But to my dismay I have been unable to find one. The only other option is to purchase a 30A male and female repair plug (allows for disassembly to make wire connections) and purchase some 3 wire cable plus a ground and make your own adaptor cable assembly with the bonded neutral. This is crazy!!! Why would do that when I purchased an "RV Ready" generator??!! I'm very disappointed to say the least, especially with Champion's tech support and on line articles, which by the way, none of them tell you how to bond the neutral to ground to make the "RV Ready Receptacle" on the generator work on an RV.

It is excellent and very quiet just what I wanted

We have the 2500 dual fuel and it has been stellar. Needed just a bit more to run our AC and microwave at the same time on the travel trailer. So excited when this came out. It's about 10% physically bigger than the 2500 watt, but a small generator cover still fits it well. Same spark plug as the 2500 too.Starts easy on propane - the regulator for the 4000 watt seems to be better than the 2500 watt one which is a bear to start first time on propane. Going to get the parallel connector and run these two together at home when needed for power outages. We sold our ginormous 9000 watt Champion which covered 2/3 the cost of this one.I think Champion hits the mark on quality and value. You could pay a lot more for a Honda and not even get the dual fuel capability.

This is nice generator but I am only giving it 3 stars for being toted as "whisper quiet"... it's not. My advice... if you don't like a lot of noise, buy the smallest generator that will work. If you find this generator is too noisy, you can't return it.
