We've had power go out here in SoCal a few times. Really not too bad with the insulated snake room. My biggest concern is when I have eggs in the bator. That's usually the most stressful for me. In the wild, they will have some fluctuations in temps from time to time. So a little cool weather for a short period shouldn't be too bad. One thought that I have and I don't know how if it would work for you is a portable generator.
