Went from great to no just ok.

Would Recommend

When we first purchased this inverter it would run like clockwork. We changed the oil always kept the engine clean and ran it every few months when not in use. After about a year the battery needed to be replaced as it would not start with the key. Then it has issues with even starting with the pull. Now again the battery will not hold a charge. About 3 months ago it would not even turn over. We attached another battery 3rd one in 4 years and after several attempts it finally started. Now it has...

Follow instructions and it runs great

I use this for my RV. It runs everything I need to enjoy my camping trips. It is a little louder than I thought it would be when its not on Eco mode.

Excellent generator but poor battery life

Would Recommend

Excellent generator. I have used this on my toy hauler for the past 2 years.but the starting battery only lasted a year and a half and I haven't been able to find a replacement unless you get it directly from champion witch is kinda of a pain!!

Excited for the many uses

Would Recommend

We bought this for a few reasons including camping and powering our house if an outrage lasts too long. I do many side projects where power isn't available and this will be awesome and convenient. Assemble a really easy and the unit doesn't take up too much space in our garage. Sending a bottle of oil with the unit should be standard. We didn't receive one with ours. If lawnmowers come with oil, these also should.

Mighty little guy

Would Recommend

I am a first time user of generator and live in an isolated area. I bought it for power outages, that happen quite often here. I haven't had to use it for emergencies yet but have given it quite a bit of use: jumping my car or just bringing power anywhere around the farm. Love the electric start.

Earned a New Customer!

Would Recommend

This generator works great! It's compact, so it doesn't take up a lot of space in the work truck or on the job site. The controls are easy to use and understand. Will be purchasing more in the future!

Easy set up, early stages

Would Recommend

Easy to put together. Wish they told you how much oil to put in instead of don't over fill. Not as quiet as I thought but quieter then the generator. (Have both going side by side currently). Wheels are a little cheap just plastic and everything it held by pins. Bought for a trailer and camping. Excited for the remote start which kicked it on. Right now no major issues!!

On the fence

Would Not Recommend

I've had this about 2 years. When I got it there were no problems. The 1st winter I noticed it would not start on matter what I tried if it was under 40 degrees. If I brought it inside for an hour it would start right up. Same thing the next year. It ran fine during the summer but no start in winter. There are fewer than 10 hours on it. I will be contacting for warranty service and will update later.

Great Product and works well. I highly recommend it.

Would Recommend

I have owned this product for just over 1 year. It works well and will deliver the rated power. Please note it does not have a 220V output. Only 120V. The remote start works well. I connected an oscilloscope to the output and looked at it under load and with no load. It was a very clean looking 120VAC 60 Hz output as expected. I also connected it up to the house and ran a couple of TVs, a desktop PC, a laptop PC, two refrigerators, a bunch or celling lights and the modem for the internet all at ...
