No. The PortionPro Rx operates off a standard wall outlet so in the case of a power outage no food will be delivered to the bowl. However, we do have an internal battery that stores the time and all settings so that when the power returns the feeder will continue to function as usual. If a meal or multiple meals are missed during the power outage the PortionPro Rx will display an alert code to notify you that your pet missed a meal.
