This generator saved my family during a winter storm by supplying power to our main house heater, refrigerators, freezer, TV, internet, and a charging station for cell phones and devices. We were out of power from Monday morning at 8am, until Thursday night at 7:15pm. On Thursday, I ran the generator from 8:45am until 7:10pm straight, without refueling, while everything was plugged in and running. Best purchase I could have made.
