Interface design, Rendering, then began ready for mass production on August, 2014. The highlight of the new interface is more thin design, faster transmission speed (maximum 10 GBps) and stronger power transmission (maximum 100 w). Type – C double-side pluggable interfaces the biggest characteristic is to support the double sided insert USB interface, formal solved the “USB plug difficulty” worldwide problem, both the top and bottom side could be inserted. At the same time supporting the use of USB cable with it must also be a finer and more portable.
