Abstract: Devices herein generally describe a protector for a device such as a phone or tablet that includes a magnet and allows for the transfer of power and data. The protector is generally flat, and affixes itself to the back of a device using the magnet. To prevent unintentional rotation and/or sliding off with respect to the device, rather than surround the device itself, the protector includes an opening that surrounds a protrusion on the device, which may include the device's camera.
