CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Application No. 62/346,124, filed Jun. 6, 2016, which is hereby incorporated herein by reference in its entirety. 
     
    
     BACKGROUND 
       [0002]    As of today, the smartphone became the most personal device on the market. Consumers use it for work, communication, entertainment and more during all time of the day. One of the biggest drawback of the smartphone is its limited mobile battery source. The market is full of competitive mobile battery charging devices. These mobile devices are charged while connected to a power source and can charge a smartphone without being connected to a wall or desk power outlet. Most of these devices require the use of an external AC wall chargers or bulky cables and are inconvenient to carry them around nor charge the smartphone and use it at the same time. 
         [0003]    The present invention is convinced the above problems and provides an improvement to overcome these problems with an all-in-one thin body structure. 
         [0004]    As of today, the smartphone is perhaps the most commonly used personal device on the market. Consumers use it for work, communication, entertainment and more during all hours of the day. One of the biggest drawbacks of the smartphone is its limited mobile battery life. The market is full of competitive mobile battery charging devices. These mobile devices are charged while connected to a power source and can charge a smartphone without being connected to a wall or desk power outlet. Most of these devices require the use of an external AC wall chargers or bulky cables and are inconvenient to carry. 
         [0005]    While battery technology has made significant improvements, battery technology has not evolved to the point where devices are capable of storing sufficient power to keep devices operational for extended periods of time. 
         [0006]    Prior solutions to this problem, as for instance as set forth in commonly assigned U.S. Pat. No. 9,438,298, hereby incorporated as though fully set forth herein, provides a charger apparatus for charging a rechargeable device, including a floating base bar having a DC plug mounted thereon. The DC plug providing DC voltage to a charging port of a rechargeable device. The floating base bar supporting said rechargeable device during charging. The floating base bar moving from a stowed configuration in which said floating base bar and said DC plug conform to the slim shape of said casing, to a charging stance in which floating said floating base bar projecting beyond said casing such that said DC plug is exposed from said casing, and such that said floating base bar can support said rechargeable device. It was discovered that some cell phones have protective cases that create a cavity which must be traversed before a plug can access the charging port of the rechargeable device. In addition a plurality of unique and proprietary interfaces exist on the rechargeable devices. Therefore there is a need for a charging apparatus that can work with a wide variety of rechargeable devices including devices with bulky protective cases, and with evolving and proprietary interfaces all without the need for cumbersome wire which have been previously recognized as cumbersome and prone to damage. The present invention overcomes these problems with an all-in-one charging system which can charge devices with bulky protective cases, adapt to evolving and proprietary interfaces without cumbersome wires. 
       SUMMARY
