It powers the majority of my house if I loose power. TV, Netflix, router, 2 fridges, freezer, furnace, hot water heater, and lights where needed all work flawlessly.
Easily to complete and ready for use. Took only about 15 minutes to complete assembly and we were off and running. Started right-up - electric start is great. Haven't really had to use it yet. However it seems like a well designed unit and very heavy duty.
