  • Great buy…
Color: Dark Grey
The media could not be loaded. This runs laps around any 3500+ watt generator. I’ve almost put 7 hours on it and going to change the oil at 10. Starts right up first pull the few times I’ve ran it. Very quiet and for the price, it’s a steal. If you’re in the fence, don’t be and buy it. Doing my hurricane prep running a 10k btu window unit just in case and it’s pretty quiet. ... show more

Very unhappy. Brand new. I’ve done everything by the book and it won’t stay running. Will not buy again.

  • Highly recommend for home backup or outdoor use!
Color: Bright Red
This generator has been a lifesaver! It starts easily and provides enough power to run all our essential appliances during outages. The build quality is solid and it runs smoothly without being too noisy. I especially appreciate the fuel efficiency and how long it lasts on a single tank. It’s also portable enough to move around when needed. I feel much more prepared now for any power failure. ... show more
