Type-c data Bai line refers to the data line of USB Type-C interface DU. USB Type-C is referred to as Type-C, which is a general serial total ZHI line (USB) hardware interface specification. dao Highlights of the USB Type-C interface include a thinner design, faster transmission speeds (up to 10Gbps), and stronger power transfers (up to 100W). The most important feature of type-C double-sided pluggable interface is that it supports double-sided USB insertion, formally solving the worldwide problem of "USB is never pluggable". The USB cable that comes with it must also be thinner and lighter.
