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.
The Lightning connector is much more compact than the previous connector and can be inserted with either side face up. The downside for consumers is that the Lightning connector is incompatible with cables and devices designed for the older 30-pin connector, although an adapter is available that the Lightning connector can plug in to in order to work with these devices.
