The new interface features a thinner design, faster transmission speeds (up to 20Gbps) and stronger power transmission (up to 100W). The biggest feature of type-c double-sided interchangeable interface is that it supports USB interface double-sided interchangeable, which officially solves the worldwide problem of “USB is never interchangeable”.
