User Reviews
We needed a medium-duty generator primarily for backup power for a small data center. We were impressed with the quietness of the Honda EU2000 inverter-generator, but chose this because of the larger fuel tank, lower price, higher output, and more rugged look. We have not been disappointed.
It sounds a little louder than the Honda, but is still way quieter than most small engines.
Inverters rarely put out a perfect sine wave, but this one is clean enough to run all of our equipment, including one piece that shuts down when operated from an auto battery and a "modified sine wave" inverter.
It was used for a ham radio field day -- a simulation of emergency operations. It ran 5 transceivers, 5 computers, lights, fans, coffe pots and the like. This is the first time it had been used except to test it in our data center. We ran it for 10 hours, then shut it down to change oil (always a good idea to prolong the life of a new engine) and fill the fuel tank. It ran about 16 hours on a tank -- it was at idle unless a couple transmitters were going at once.
After the 16-hour run, one of the motor mounting bolts had come completely off, and another was loose. So keep an eye on that. We used Loctite and hopefully that will take care of it.

[...] -- Great generator
We bought this generator to power our RV and have had absolutely no trouble with it for 5 years now. It runs our AC unit and that is what we wanted. It is super easy to carry around, I can do it myself and I'm a medium sized woman. We did not buy a bigger one because of the extra weight and have never been sorry. If I need to use the microwave or the electric water heater, I shut off the AC and run the other stuff. It is pretty quiet when compared to other generators in camp and it starts up easily every time, no matter how long it has been. We usually find it takes a fill up on fuel after about 7 hours of running and does fine if you have to run it continuously for days at a time. We would buy it again, and recommend it to other campers. -- Reliable, easy, lightweight
I bought this generator from Amazon about five years ago in order to build our house. It supplies plenty of power to start and run 15 amp saws, compressors, etc. Because our house site is about a quarter mile from the road and one of our neighbors was difficult, it took nearly 18 months for us to get power from the grid. During that time I would have to estimate that the generator ran for 2000-3000 hours. Today we use the generator just for emergency backup; it can handle two refrigerators, the circulating pumps for the heat, lights and the TV, all at the same time without any problem. This generator is relatively quiet, quite efficient, and very reliable. When we run it at slow idle, which is all we need for backup, it only consumes about 6 gallons of gas per 24 hours. Even after all of the hours that it has run, after sitting for six or more months without being started, the generator still starts with ease. I would buy this generator again without reservations. -- Excellent generator
I have owned the non-GFI exact twin of this generator for about 5 years. I use it for tailgates and as an emergency generator. This little dynamo ran continously for four and one half days this week due to an ice storm taking out power in Tulsa for around 250,000 customers all week. The generator was barely powerful enough to run my clothes washer and it couldn't get my gas dryer started. No biggie. It easily ran my gas furnace from a pig tail off of a switch, refrig., small TV, crock pot, laptop and a couple of small curly Q low wattage lights using heavy and not so heavy extension cords. Basically covering all of my emergency power essentials. This was using the economy setting on the generator. The generator had electric power to spare. In the early morning it even ran my Mr. Coffee. I only had to fuel it twice a day. All week long during the ice storm my friends were either freezing or scrambling to find a loud, heavy, low quality junk generator at a hardware store. Not me! -- Great tailgate and emergency generator
If you want a generator that you can carry by yourself, this is a good choice. It is designed to be light and quiet and meets those goals quite well. I think if you figure the Kw to pounds ratio, this unit will compare favorably to most of those out there. I don't know why someone would try to hardwire one of these to a house. For that, you need a much larger unit. I actually chose the consumer model, EF2800. It came with a longer warranty. I also did not want the GFCI because I've had problems with those types of devices tripping on the starting current for a freezer. -- Great portable power
