Nice, solid unit.

I mistakenly purchased this brand as I got distracted and thought I was buying the Champion. That being said, this seems a really good, solid little unit. It starts well and is quit. I hope it turns out to be durable and serves me when I actually need it. I also have a huge, 13000 generator for my home and also use solar power stations which this can help charge. So far, I am happy with this purchase. Also, it arrived quickly. The time to get these is now, before we have a storm in the Gulf :-).

good

The generator is not "wisper" quiet. It is about comparable to a small air compressor for an air mattress. I believe the power is as advertised. I do not think it will be ok for a campground that has quiet hours at night.

Unit arrived well packed and undamaged. Read over the owners manual , put in oil and gas and replaced the plastic oil dipstick with a magnetic one. it fired up on the second pull. It runs very smooth and very quiet for a generator of its size. Been breaking it in by running it one hour with a light load and then changed the oil. After four times doing this the oil finally came out clean. So far very impressed with the build quality and that it has a slightly larger gas tank at 1.3 gallon. I also swapped out the torch spark plug and replaced it with a ngk. The info meter has a gas gage and a power percentage gage that shows how much power it is producing and how much more is available . So far so good. Will See how it goes long term .
