Description:
BACKGROUND 
     1. Field of the Invention 
     The present invention relates generally to a phone charging system, and more specifically, to a retractable charging system for a phone case. 
     2. Description of Related Art 
     Cell phone cases are well known in the art and are effective means to protect the phone from damage during use.  FIG. 1  depicts a case  101  having a body  103  contoured similar to the outside surface of a phone (not shown) and configured to securely engage with and protect the phone during use. 
     Phone charging electrical systems are also well known in the art and are adapted to provide the phone with electrical energy.  FIG. 2  depict a conventional charging system  201  having a wall adapter  203  and a phone cord  205 . The phone cord  205  includes a USB connector  207  and a phone adapter  209 ; both being attached to an electrical conductor  211 . The wall adapter  203  includes a body  213  with a USB port  217  configured to engage with USB connector  207  and a plurality of metal terminals  215  in communication with the port  217 . 
     During use, the owner will connect the terminals  215  to a wall outlet and engage the USB connector  207  with USB port  217 . Thereafter, the owner connects the phone adapter  209  to the phone for charging. 
     A common problem associated with the above-described process of charging the phone is that the owner will typically carry the charger system  201  during travels, which in turn can create a carrying burden. 
     Although great strides have been made in the area of phone cases and charging systems, many shortcomings remain.

     The system and method of use in accordance with the present application overcomes one or more of the above-discussed problems commonly associated with conventional phone cases and charging systems. Specifically, the system and method of the present application provides rapid and effective means to carry and recharge the phone during use. This feature results in significant improvements over existing phone cases. These and other unique features of the system and method of use are discussed below and illustrated in the accompanying drawings. 
     The system and method of use will be understood, both as to its structure and operation, from the accompanying drawings, taken in conjunction with the accompanying description. Several embodiments of the system are presented herein. It should be understood that various components, parts, and features of the different embodiments may be combined together and/or interchanged with one another, all of which are within the scope of the present application, even though not all variations and particular embodiments are shown in the drawings. It should also be understood that the mixing and matching of features, elements, and/or functions between various embodiments is expressly contemplated herein so that one of ordinary skill in the art would appreciate from this disclosure that the features, elements, and/or functions of one embodiment may be incorporated into another embodiment as appropriate, unless described otherwise.
