The birth of Type-C interface originated from USB3.1. After the USB transfer rate reaches the USB3.1 standard, USB-IF announced the launch of Type-C interface to meet consumer demand upgrades. The advantage of the interface is its compact size, which can be inserted forward and backward. It can carry up to 10Gbps of data transmission speed, withstand 100W of power transmission, and can also be used for video transmission. Type-C not only has extremely advanced functions, but also has a smaller size, higher compatibility and performance. Therefore, it has been widely used in various electronic products such as computers, smartphones, tablets, peripheral accessories, storage hard drives, etc., gradually becoming the mainstream unified interface recognized by the public.
