Do you have a power converter for the Incubators?

No, we do not have a power converter and no the Incubators do not run off batteries as back up. If you are having storms and lose power you can plug your Incubator into a generator to keep the set/hatch going and not lose your eggs/chicks. If there are a lot of voltage fluctuations, you can also get a voltage regulator so the voltage change doesn't burn the incubator.
