Techopedia explains Lightning Connector. The Lightning connector was a successor to the previously used 30-pin connector. It is a small wire with a USB 2.0 interface at one end and a connector plug at the other. The connector consists of a communication bus for dual data transfer; it also provides electrical power to the device.
Enter the Charge Card: a flat, credit-card-sized USB cable that can be easily carried in a wallet, and now supports Apple's Lightning connector. Until recently, the Charge Card has been available with support for Apple's legacy 30-pin dock connector, as well as micro USB for non-Apple devices.
