4000W Dual Fuel RV Ready Portable Inverter Generator with CO Shield

I got the Champion 4000-Watt Dual Fuel Inverter Generator mainly for work, and it’s been a solid purchase. I transport cars in an enclosed trailer and use it to run my vacuum for cleaning inside. It handles that with no problem and has plenty of power. We’ve also used it at home during outages, and it’s such a relief knowing we have backup power ready. I love the dual fuel option — switching between gas and propane is super easy. Easy to use: Setup was quick, and it didn’t take long to figure out how to run it. Portable: The handle makes it easy to move around, which is great since I take it with me often. Noise: Not silent, but quieter than other generators I’ve had, and the sound doesn’t bother me while I’m working. Overall, this generator is reliable, versatile, and simple to use. Perfect for both work and home. Definitely recommend it if you need portable power with the flexibility of dual fuel

Build quality is very good. Fit and finish are good. The new easy-start system works great. The genset switches from eco (lower output, lower volume) to full power based on the load - no switches to adjust. Runs well on LP gas which is cleaner and more convenient for camping. A well priced portable unit.

Purchased this to run my camper, It worked great! some notes, If you want long life out of this generator, run the generator for the 5-6 hours break in and then change the oil. do this before putting heavy load on the generator. the dual fuel capability is very nice, but the estimated run time is only for an unloaded idling generator. running the camper AC on a 90 Deg F day cut the propane run time to 10 hours and gas run time to 5 hours. (to be expected) Starting on propane is not as easy as starting on Gas, but both are fairly straight forward. Once running this is fairly quiet, we put it on the back side of the camper and could barely hear it. This being an inverter style it is fairly compact and relatively light (as compared to similar output generators) which makes it nice for loading in the camper or using around the farm.

Effective and efficient. Powers my 17ft camper very well when dry camping, including the AC (11000 BTU). Worth noting it is rigged to prevent you from hooking up at a quick connect on a camper, but there are plenty of YouTube videos showing how to rig around this. Fairly easy to crank as a solo female camper.

Works great. I only run it on propane. Haven’t had any problems so far. Decently quiet On the cold start put the choke on, slowly pull three to four times to prime it. Then put it on propane and it starts right up, every time first pull.

Excellent generator, this is my second one from them, the first one was the 2200 or 2500 W one.. they got burned up , from not being level and causing the oil light sensor not to come on , but the first one probably had a couple thousand hours on it anyways .. nothing to do with the manufacturer at all… this definitely is slightly heavier, great option to have Propane and Gas.. I use this on a camper, ron Tiki lights, fans, a small window air-conditioning, and this allows it to be on eco the whole time now .

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.

This is my third Champion generator. It works great, as the others do. They are a great value.
