Great little generator for RV and Backup power

This little Giant of a Generator powers my AC and the converter with ease. It is light enough for me to handle. It starts well. It is not loud, but not as quiet as the little Yamaha that it replaced to get more power. The delivery was fast. Overall, it is a very exceptional value.

Great Inverter Generator!

Arrived undamaged. Started on first pull which was very satisfying. I decided to change oil during break-in at 1hr, 3 hr and 5 hr of runtime. It did arrive with a container of oil. Break-in was done with various loads per the instructions. This was a great purchase (during Black Friday week) and I now have a great backup power source for a power outage. I plan on using it to charge my Jackery power stations.

1st class

I live in South Louisiana, “hurricane central”. This is a superb machine. I have the set up to a fine science. I power small a/c, refrigerator, TV and lamps. 1st class camping in your own home during storms. I keep it on a small furniture dolly I picked up a Harbor freight for $12. I push it out of the corner and purrs like a kitten.
