Features USB3.1 (also called Gen.2) brings many improvements to the previous standard USB3.0 (Gen.1). The most noticeable is the new Type-C connector which is much smaller & reversible. The Type-C connector is backwards compatible & can be used with USB3.0 PCs & devices. Type A to Type C This cable features both a Type-A socket & a Type-C connector making it the perfect solution for converting a new Type-C socket into a Type-A socket. Perfect for plugging your USB (Universal Serial Bus) flash-drive into a modern ultrabook. Reversible Connector The new USB (Universal Serial Bus) Type-C connector is smaller than most of the previous USB (Universal Serial Bus) connectors. (Micro B is the exception.) It is also symmetrical; this means that you can plug the connector in either way up.
