Abstract: There is provided a removable casing for an electronic device, the casing including: a battery for powering the electronic device; a cavity for receiving the electronic device; a pivoting connector extending from the cavity, for interconnecting the electronic device to the battery; the pivoting connector configured to pivot between: a first position in which the connector extends at an angle relative to a rear surface of the casing, thereby allowing the electronic device to be connected to or disconnected from the connector when the electronic device is oriented at said angle to the back surface of the casing; a second position in which the connector is substantially parallel to the rear surface and allowing the electronic device, when connected to the connector, to be substantially parallel to the back surface and received within the cavity. The removable casing may have antimicrobial agents, wireless communication devices, or UV resistant coatings.
