Champion Power Equipment4000-Watt Dual Fuel RV Ready Portable Inverter Generator with Quiet Technology and CO Shield

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!

Good name brandGreat qualityRuns great:GreatGenerator quality:5 starsFunctionality:Perfect easy to run - bit heavy

Awesome generator! Quiet and efficient and reliable

I currently own a pair of Champion 2500W dual fuel inverter generators, along with a 50 amp parallel kit. When I saw that Champion came out with a 4000W dual fuel inverter model at a very reasonable price, I decided that having a 3rd one around the house wouldn't be a bad idea due to periodic power failures in the area. I had read some reviews indicating that they had issues running this 4000W model on propane, but thought to myself that they must not be following the directions in the owners manual. Well...I followed the instructions to the letter, and no matter how hard I tried I could not get it to run off of a brand new (and full) 20 pound propane tank. I gave up after about 45 minutes and filled the gas tank with fresh gasoline. I put the dial on the "choke" setting, and after 1 pull it started right up and I moved the dial to the "gasoline" setting. I ran the generator on gasoline for about 90 minutes to break it in, and then began applying small loads. It worked perfectly.The next day, I tried the propane again, and now it's working perfectly on propane. I don't understand why it needed to be broken in on gasoline first, but I drained the gas tank and will mostly run this generator off of propane.The biggest differences between my new 4000W dual fuel model and my pair of 2500W dual fuels are: (1) the weight (the 4000W model is 52 pounds as opposed to 39 pounds for the 2500W model - at 70 years old this 13 pound difference is noticeable), and (2) the noise level (64dBA from 23 feet with 25% load, as opposed to 53 dBA from 23 feet with 25% load) - this is a fairly significant difference, and my research indicates that the 4000W model could reach 70dBA at full load.All of this being said, I think that the new 4000W dual fuel model is decent, especially since it is RV ready. It has both a 30 amp RV plug, as well as a 20 amp receptacle. Until there's a power outage at home, I take to the storage lot where my motorhome is so that I can power it up and run one of the air conditioners while I'm working on it. The price I paid ($699) is not too bad, especially since I paid $630 for EACH of my 2500W dual fuel Champions back in 2022.

I love this generator! Very easy to use and is light weight. We have a lot of power failures and this is a life saver.I highly recommend this generator.

I bought this gen back on March 23, 2025. By April 14th it stopped and wouldn't start again. I called Champion and they had me do things like check the plug, oil etc.. and they came to the conclusion that It was one of 2 parts needing replacement. They sent me the parts, but there was no way to get into where the parts were. I called back and got a different service person who said they were all wrong and I need another part instead of the ones they sent. Then she said I need to prove I bought the generator. I sent them a copy of the Amazon receipt and was told that would not pass for a receipt. I finally got so disgusted, I called Amazon and told them the story. They said that's the only receipts they have. They said don't bother sending it back, and Amazon simply replaced it. That was great of Amazon. It is now 3 months later in July and this generator started white smoke, no electric and I shut it off. I waited a bit and pushed all the resets and it started and ran like new for about 1 minute and then shut off. I saw I needed to change the LPG tank and then I couldn't get it started again. I've only ran LPG in it because it's cheaper and easier Now it won't start period. So, here I am calling and calling and waiting and waiting and it's a 20+ minute wait and then they closed. The warranty and website say 24/7 support, but that's not true. It's 8 - 8 eastern time. I'm out in the wilderness with a 3 month old broken generator and no support. Today is the 18th so I am 4 days past Amazon's return days. 2 bad generators in a row in just 3 months I run the generator for 1 hr. mornings and evenings unless there's rain or clouds. I run solar the rest of the days.

It's a really good purchase, I ran the engine as per the oil directions, and then left it on for 3 hours and no problem do its job and it's great to carry great work

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.
