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.

Abstract: Port extension apparatus for providing better usage and utilization efficiency ports of end-user devices are disclosed. Port extension apparatus includes at least a main port module for connection to end-user device, first data port module, data transmission control module, second data port module, and video port module. When a to-be-connected device connects to the first data port module, the first data port module and the main port module form a transmission path enabling data transmission between the to-be-connected device and the end-user device. When the to-be-connected device connects to the second data port module, the data transmission control module controls the data transmission between the to-be-connected device and the end-user device. When the to-be-connected device connects to the video port module, the data transmission control module receives the to-be-displayed information from the end-user device and transmits to the to-be-connected device to display.
