The present invention relates to a charging system for a mobile communication device, and more particularly to a charging and telecommunications transmission system for a mobile communication device.

Electronic products have become more and more popular in modern society. The best examples are mobile communication devices, such as mobile phones and personal digital assistants (PDAs), which usually have rechargeable batteries inside. Used as a source of electricity when used as a mobile communication device.

When the power of the rechargeable battery is exhausted, there are generally two ways to charge the rechargeable battery. One is to take the rechargeable battery out of the mobile communication device, and use the charging battery-specific charging stand for charging, and the other is The rechargeable battery is left in the mobile communication device, and the mobile communication device is connected to the external power source to charge the rechargeable battery.

Please refer to the first figure and the second figure. The first figure is a schematic diagram of a conventional technology for charging a mobile communication device by using an electronic device, and the second figure is a schematic diagram of a mobile communication device using a transformer to connect to a commercial power source for charging. The mobile communication device 11 is electrically connected to the electronic device 200 for charging. The mobile communication device 11 includes a control processor 111, a power storage unit 112, a telecommunications communication port 113, and a power port 114.
