Broken in

I just finished installing a transfer box and outside outlet. I needed a generator to power the whole house. I purchased the 11000 watt dual fuel generator for that purpose. I ran it for 5 hours and alternated loads. I had everything in my house running as normal including furnace. The only time I could get it over 50 percent was when I turned on the dryer and that pushed it up to about 75 percent, it is very quiet hopefully works out for me.

Reliable, Fuel Flexible and Convenient

After a lot of research, I decided on the Champion 11,000W Dual Fuel Inverter Generator, and so far, it's been one of the best investments I've made for home backup power. Living in an area where storms can knock out power unexpectedly, I wanted something reliable that could run the essentials without worrying about fuel options. The dual-fuel feature has been a huge plus because I can switch between gasoline and propane depending on what's available. The electric start is incredibly convenient, especially when you're dealing with an outage and don't want to fight with a pull cord. I was also pleasantly surprised by how quiet it is for a generator of this size. It easily handles my refrigerator, freezer, lights, and other household essentials, and I feel comfortable using it around sensitive electronics thanks to the inverter technology. It's definitely a large, heavy unit, but that's expected for the amount of power it delivers. Overall, it gives me real peace of mind knowing my family can stay comfortable during an outage. I would absolutely recommend this generator to anyone looking for dependable backup power.

Really Nice Generator

Got this generator for home emergency backup. Wanted to get the break in time in so hooked to deer cooler and was super impressed by how quiet it is. Could have a conversation right next to it without yelling. Will look into getting 2nd smaller one to use on outbuilding as well. Great buy!

Great generator

I purchased the Champion 11,000-Watt dual fuel inverter generator a little while back . I wanted to use is a few times before I gave a review. This a great machine. The last storm took out most of my town. This unit started right up .Ran everything in my house including 2.5 ton ac. for few days. Incredibly quiet for its size. I think at just under half load I got a good 10 or 11 hours on a full tank of gas. And when any major loads kicked like my well pump the generator didnt flinch. I would highly recommend buying it.

Very Powerful Generator, can handle large loads

I bought this inverter/generator as a back up power source to my home and or Travel Trailer. I am new to owning a generator but found this one to be super user friendly and easy to figure out. I did the 5 hour break in period and ran the travel trailer, a couple of garage refrigerators and my well. I didn't run them at the same time but this thing is so large that pretty sure it could run it all with no problem. After the break in period of 5 hours, I followed the instructions for changing the oil and storing it. I did the break in period over a three week period and I was impressed at how easy it was to pull it out and start it up each time. This unit is quite large, probably could have gotten by with a smaller unit but can't change that now. I bought the storm shield model 100603 but was a little disapointed that because the exhaust is mounted high on the unit, the shield can not cover the unit like I thought it would while its running in bad weather. I can report that the CO Shield works. If you install the storm shield like the instructions say, it will be too low and will trap CO under the cover and the generator will shut off. I raised the cover so that the exhust does not get trapped under the cover and it ran perfect.

Extremely satisfied

[This review was collected as part of a promotion.] I've had this generator for about about 8 months. I had used basic open frame generators before, and after a burned out furnace board and two fried garage door openers, I got into the market for an inverter. I needed one big enough to run our residential well, but also wanted one that ran off propane. That really limited my options, but this one ticked all the boxes. Setup was easy. Manual has a good amount of information in it regarding all the maintenance, setup, startup, and shutdown procedures. The unit is very easy to move with the large handle that snaps up or down when moving/stored. Pretty maneuverable as well, easy to keep tucked into the corner of the garage. I've ran it almost once a month just to keep it exercised since buying, but we've also needed it twice during power outages in that time. Both the electric start and the pull start work great. The battery is really easy to access behind a panel with two screws, so I've been disconnecting the battery between each use, and have had no battery problems. We'll see how that fares as we go into winter, but so far no issues, and it's powered everything I have needed to. I'm very impressed by how quiet the unit is. Even at 80% load, it's still quieter than any open frame unit I've ever used. Personally i think this is a fantastic buy. Quieter, more reliable than a cheap open frame unit, but didn't have to spend the equivalent of a car purchase on a whole home unit either. Extremely pleased!

Quality Control

Although I haven't ran the unit except for testing it seems to operate efficiently and reasonably quiet. Installation of the hardware for the wheels and support legs proved challenging as none of the brackets aligned with the pre-drilled holes. All of which required re-tapping due to paint overspray. I can hope the units long term performance matches Champions reputation. Time will tell...

Very nice generator, with one flaw

Seems to be a well constructed unit and much quieter than a non-inverter, open frame generator. It started easily and I ran it for the 5 hour break-in period. At the end of this I flipped the breaker on our 5500 watt water heater and it handled that as well as some miscellaneous lighting and vampire loads, floor heat in a bathroom, etc. The red 100% load light was coming on intermittently. This is at 2500' so it will lose almost 10% of rated power. After Helene, we decided we needed a generator large enough to run the water heater! I subtracted one star due to a design flaw. There is a raised plastic ridge around the instrument/breaker/outlet panel. The 50 amp outlet is too low causing the molded housing on a 50 amp cord plug to interfere with this plastic ridge. Two different cables had the same issue. So I had to cut part of this ridge away to firmly seat the plug. That really needs to be changed. Just mold a relief into this ridge below the 50 amp outlet so the customer doesn't have to perform surgery on a new generator to make the 50 amp outlet functional. Other than that, I am satisfied with the performance, although I hope not to have to use it. It is now prepped for long term storage awaiting the next power outage.
