2200 watt Honda generator and 5-10 gallons of gas could keep your freezer frozen for a month or more if that is all you used it for.
I figure a gallon a day (8hr run time) to selectively run a couple of refrigerators, a freezer, lights, portable space heater, electronics, including battery charge for my microwave communications transmitter. (mine is the older 2000 watt Honda generator)
Thank you! We will be getting another, BIGGER generator as soon as it’s practical. :)
