If the electricity goes out, depending on the type of bator you have, you are better off not opening it. Adding hot water bottles after the fact will be difficult to control the temp.
The eggs will survice a few hour outage.
I have an 12V to 110V inverter for a car hooked up to a marine battery (actually a bank of them) for extended outages
Ooo, we have an inverter for a car too! We have several cars that run so if the electric goes out, we could do that. I just have to remember it. LOL
