The LocknCharge Revolution Wall Cage is an open design USB charging station for tablets, notebooks, Chromebooks, and other mobile devices. It features 10 felt-lined compartments that can be used simultaneously. It's wall-mountable and the doors can be locked with a standard lock, so it can be used to secure devices in a classroom or similar setting.
The open design allows for passive ventilation, and also allows a teacher or admin to quickly see if all the distributed devices have been returned after use. The Revolution Wall Cage also has overload protection, so your devices are safe from sudden power failures and surges.
