I got a Generac 3600 just for emergency use. It was 459 bucks. Haven’t had to put it to use yet, but believe it will do what I need to get by. Keep the fridge and freezers up by rotating, run a few lights, tv. And if need be unplug a few things to run space heater, although have a kerosene heater. And as far as cooking the black stone has a full tank of propane.
