PORTABLE DOCKING DEVICE CAPABLE OF PROJECTING VIDEO CONTENT

摘要

Provided is a portable docking device. The portable docking device may convert an USB Type-C port to another type of port. The portable docking device can further receive electric power from a mobile device connected with the portable docking device, and the pico-projecting unit can receive the electric power to project an enlarged screen synchronous to a screen displayed on the mobile device. Therefore, the screen displayed on the mobile device can be enlarged, and viewers can watch the enlarged screen without the viewers' sight being blocked. Further, the user of the portable docking device does not need to bring a power adaptor, and convenience and portability of the portable docking device can be improved.
