The USB 3.0 Promoter Group has now finalized the spec for a new connector and cable, USB Type-C, that is much smaller than current USB ports and cables. It is also designed to offer reversible plug and cable orientation, meaning that users will be able to insert a USB Type-C cable in its supported port in either direction.
The port will support USB 3.1, otherwise known as SuperSpeed USB, which will offer data transfer speeds of up to 10 Gbps. The port will also support power delivery up to 100W. However, the new connector and cable design does meant that current USB devices will have to use adapters to use the Type-C products.
This news means that at some point, many upcoming smartphones, tablets, notebooks and desktop PCs will have USB Type-C ports, which could make them easier to use for consumers. The only catch is that it may be a little while before the first products are released with USB Type-C connections. Today's announcement gave no indications of a launch date for the new spec.
