This Power Pack will extend the battery life of your Browning Trail Camera in the field and reduce the number of visits that you must make to it. This micro sized battery pack comes with a durable mounting strap and holds 8 AA batteries in the same easy to use battery tray used in all Browning Trail Cameras. Additionally, it is decorated with one of Browning Trail Cameras’ registered camouflage patterns to help conceal the pack. Other features include a built-in battery tester and a “twist lock plug” to secure the power adapter to your Browning Trail Camera. Batteries are not included.
