Lightning connectors are a type of connector designed for use in electronic devices, such as iPhones and iPads. The connector is an eight-pin, all-digital interface designed to replace both the 30-pin and USB ports found on older Apple products. Lightning connectors are significantly smaller than their predecessors and have an increased data transfer rate. They also provide better power efficiency. Lightning connectors are capable of carrying audio, video, and data files, as well as charging the device.
