Rated 4.4 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by Best generator ever Filled with full synthetic 10/30 Mobil oil. Ran for 6 days straight to fill a huge pond on our Ranch and ran some lights in the cabin. The only time it ever stopped running, was when I filled it up with Gas/Petrol again 13 hours later. We could hardly hear it in our cabin on the Ranch. This generator ran for 6 days straight without as much as a miss or a hiss. I am in the process of purchasing another 3 of these generators. If they put this generator on special again for $399 I will purchase 5 of them foreshore. Over the past 9 years I owned 14 generators from generac to Ridgid to Powermate to Briggs and Stratton and nothing beats this nothing beats this. February 25, 2016
Rated 4.0 out of 5.0 by Quiet little generator Got this generator to charge a PV battery bank, it is very quiet and I have had no issues and its been in service for 4 weeks now. My only issue was the cosmetic damage to the generator that was apparently done before it even went in the crate. Based on the time its been in service I would buy another Lifan generator. The spec sheets show it to be a 30 amp max generator but in reality and on the Lifan power website its max is 26.7 amps, that was ok for my use but could be a deal breaker for another use.

Rated 5.0 out of 5.0 by nice unit Went together ok. Only drawback was that it did not come with battery for electric start Runs most of my 14by 50 trailer November 10, 2015
Rated 3.0 out of 5.0 by nice little generator, a little shy on power. At the time I ordered this generator I had to choose between power and convenience. I am almost 67 years old and my shoulders can't take a lot of pull starting now so I chose the electric start. There is only one 220 outlet and one 120 volt outlet and you have to choose which one to use. My old generator had 2 220 outlets and 4 110 volt ones and all could be used at the same time. It was only one horsepower larger. We used it at my son's house a week ago and it had problems keeping up. He had to choose one appliance at a time to run with a sump pump. I'd recommend it for someone who doesn't have a lot of things to operate. I do love the electric start. March 18, 2014
Rated 5.0 out of 5.0 by Good product; works well; worth the price. The generator works extremely well and is easy to set up and use. Also,the out-put was exactly as claimed in the sales literature and fully satisfies my emergency electrical needs. The only difficulty was the instructions for assembly were not appropriate for the model I purchased and it took a little time to figure out what fasteners to use on each component. Other past reviewers have made this same negative comment and I was surprised LIFAN hadn't made the needed changes to their instructions. April 15, 2014
Rated 4.0 out of 5.0 by the product was what i expected The product arrived when I was told it would and the tracking was great. It arrived in good condition with everything included. I was disappointed with the instructions because they were for an older version and were about as clear as mud. After I got it assembled and got a battery ( the one recommended) the wire lead for the positive side was too short to reach the terminal. I had to bend the terminal at the starter for it to reach. I am satisfied with the unit but recommend they spend a little money and update the instructions. October 11, 2013
Rated 4.0 out of 5.0 by easy starting, runs well instructions are poor, product has been updated. some assembly is poor. it works, bottom was bent up a little when received. an attempt was made to pack it securely via an overpack with Styrofoam peanuts. don't pick up on Saturdays from the store. unneeded hardware included because of updates, get threadlocker for what you assemble. April 22, 2014
Rated 4.0 out of 5.0 by A good fit for the job I just came out of a 25 hour power outage due to a storm. The generator got us through. The power output is a good fit to the needs of the house. Ease of use really depends on how you are set up to connect the generator to the devices that need power. I haven't yet bought a battery so I don't know how well the electric start works.
