Abstract: The invention relates to a protective frame for a mobile communication device having a power charging port. The protective frame has a retractable frame body, including a main frame body; a sliding element for reciprocatingly sliding along a direction with respect to the main frame body between a retracted protection position where the mobile communication device is fixedly framed by the retractable frame body and a stretched auxiliary power supply position; and a fastening element for fixing the sliding element with respect to the main frame body at the retracted protection position and the stretched auxiliary power supply position. The protective frame also includes an auxiliary battery adapted for being detachably installed in the retractable frame body and electrically connected to the power charging port of the mobile communication device, when the sliding element are fixed with respect to the main frame body at the stretched auxiliary power supply position.
