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.
A 30-pin connector to-Lightning adapter is available from Apple for $29. Also available is a $39 7.8-inch cable with a Lightning connector at one end and 30-pin connector port at the other.Lightning to USB 2.0 cables will cost $19.Apple will also sell HDMI and VGA adapters for Lightning.here are always going to be accessories that require using the connector and nothing is ever going to be 100 percent future-proof. However, as Apple Senior Vice President Phil Schiller pointed out when presenting Lightning, a lot of what we do now is wireless.
