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

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 the 3rd generator we’ve bought and we love it! Works great and exactly what we were looking for!

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.

This thing is sweet, read the manual follow directions and it works flawlessly, super easy to use, plenty of power for my 29ft travel trailer, great runtime haven’t tried the ac yet but I’m confident it will have the capacity and be just fine.

do not order and do not buy protection plan it stopped working champion said to bad and the protection plan i paid for cancelled the plan when i reached out for help .....horrible experience out all the money and now a huge expensive paper weight

Works great on propane. Very low noise and operates my 15K RV AC with no issue!

Light weight for generator. Easy for me to move around. Powered13.5K rv air conditioner during recent camping trip. Pretty quiet, though still had to shut down at park quiet time. Being an invertor type genie, be aware that the larger the load, the more noise it will make. Got about 8-10 hours run time from a 20lb propane tank, using it to mostly run A/C to cool off camper. Note, genie will only put out 4KW for short time / start up. (3KW for continuous use). Could not use microwave if using A/C. (A/C~2KW + Microwave~1.1KW = 3.1KW) Not really an issue, just had to remember to turn off A/C to pop popcorn.

For me it is the perfect balance between enough back up power and not so much I am overwhelmed hauling fuel for it. The 3000 running watts will run my 10000 btu portable ac unit, my router and computer and a TV and a mid sized refrigerator. The power is pretty reliable here and I can get by with that. I keep 4 20lb propane bottles filled that should keep us going for 3 to 4 days before we need to refuel. The propane can be stored for long periods and the gas option is good if that is all you can find after a storm. It only weighs 50 lbs so it can be stored away and easily retrieved for use. The only issue I've had is it was very hard to start on propane at first. After the initial 5 hour break-in period and oil change it now starts easily on propane. I am very happy with the purchase.
