A charger guard apparatus is described. The guard is equipped with a sabot, wall plate, and retaining cradle which, when assembled around a mobile device charger or any AC-powered male plug, is configured to prevent unwanted movement, damage, or loss to the charger or similar AC-powered device. The sabot is preferably composed of a top half and a bottom half which are configured to lock together around a male AC plug, including any AC/DC adapter or similar plug protrusion. The sabot is also configured to encapsulate any and all cable extending from an AC/DC adapter disposed within the sabot. The retaining cradle is configured to lock to the wall plate via retaining clips which are designed to mate with clip sockets of the wall plate.
