New connector is symmetrical, similar to Apple Lightning
The USB 3.0 Promoter Group has ratified the new USB Type-C connector. Initially revealed in December, the new connector is symmetrical, smaller in size, and has scalable power charging. Additionally, the new specification supports faster speed, and is still backwards-compatible (with adapters) to previous versions of the spec.
The receptacle opening is 8.3mm wide by 2.2mm high, and is expected to have a durability of 10,000 cycles. The new cable will support up to 3A of power, up from the 2A of today's cables.
The new standard will replace full-size USB and Micro-USB connectors, and offers bandwidth at 10Gbps, about twice the speed of the existing USB 3.0 specification.
