Until now, the various types of USB A and Type B have had an asymmetrical design, which means that there is a top and a bottom, which has made plugging in an USB cable by feel a little bit frustrating to some users. Also, the old USB standards are relatively slow and carry very little charging power.
USB 3.1 standard introduces the new symmetrical/reversible Type C connector:
The new connector is only slightly larger than the older mini and micro Type B connectors and, unlike the earlier use of different connectors for the host (Type A) and peripheral (Type B) devices, the Type C connector is used at both ends.
The connector is symmetrical
