A docking station having adapter function for connecting an Alternating Current power source and target end-user devices for charging the target end-user devices and for providing data transmission paths amongst the target end-user devices connected thereon, the docking station comprising: an Alternating Current/Direct Current (AC/DC) conversion module; a power charging module; a control module; and at least a first and a second interface module; wherein when the AC power source outputs AC power into the AC/DC conversion module, the AC/DC conversion module separately outputs first and second DC powers into the control module and the power charging module according to the AC power; then the control module is enabled to operate according to the first DC power and to control the power charging module according to the second DC power to charge each of the target end-user devices that is connected to a corresponding interface module; and the control module is further adapted to control signal transmission sequence of each of the interface module to enable data transmission amongst the target end-user devices via the interface modules, characterized in that the power charging module further comprises an identification unit, a first power charging unit, and a second power charging unit; wherein a control port of the first power charging unit and a control port of the second power charging unit together connect to an output port of the identification unit, a power input port of the identification unit is the input port of the power charging module, a power charging output port of the first power charging unit and a power charging output port of the second power charging unit form the DC power output port of the power charging module, a signal sampling port of the identification unit is the identification signal sampling port of the power charging module; wherein when the AC power source outputs the AC power into the AC/DC conversion module, the control module sends a trigger signal to the identification unit causing the identification unit to operate; if the identification unit detects the first interface module being connected to a particular one of the target end-user devices, the identification unit directs the first power charging unit to charge said particular one of the target end-user devices; if the identification unit detects the first interface module and the second interface module being respectively connected to more than one of the target end-user devices, the identification unit directs the second power charging unit to charge said more than one of the target end-user devices through the first interface module and the second interface module. an Alternating Current/Direct Current (AC/DC) conversion module;
