Abstract: A docking station having adaptor function contains: an AC-DC conversion module, a charging module, a control module, and at least two interface modules. When an AC power source outputs AC power into the AC-DC conversion module, the AC-DC conversion module outputs two DC powers to the charging module and the control module according to the AC power. The control module is enabled to operate according to the first DC power. And, according to the second DC power, the control module controls the power charging module to charge each target end-user devices being connected to a corresponding interface module. When interface modules respectively connect to target end-user devices, the control module controls the signal transmission sequence of interface modules to provide data transmission paths amongst the end-user devices via the interface modules. The docking station also serves as an accessory for supplying electric power to an end-user device for endurance use.
