Power Pet 2-Battery Charger Kit for Fully Automatic Power Pet Doors

Operating your Power Pet Door is most convenient in full battery mode. This eliminates the need for the 110-Volt AC adapter. We recommend that you purchase the BATTERY CHARGER KIT and 1 EXTRA RECHARGEABLE BATTERY. Use 1 battery in your Power Pet Door and keep the other in the charger base. When your pet door battery runs low, just swap. Battery change takes less than 30 seconds.
