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 than the previous standard connectors, it is also reversible. USB Power Delivery v2.0 The USB3C-901 supports up to 20V / 5A (100W) of power. The new improved power delivery allows you to charge not only small mobile devices such as mobile phones and tablets but also laptops. Reversible Connector The new USB Type-C connector is smaller than most of the previous USB connectors. (Micro B is the exception.) It is also symmetrical; this allows you to plug the connector in either way up.
