Apple Lightning to USB-A cable. Lightning is an 8-pin digital connector. Unlike the 30-pin dock connector it replaced (and USB Type-A and -B connectors), it is reversible. [22] Most Lightning devices only support USB 2.0, which has a maximum transfer speed of 480 Mbit/s or 60 MB/s. With USB 2.0, only one lane is in use at a time.
A related term sealing current (aka wetting current or fritting current) is widely used in the telecommunication industry describing a small constant DC current (typically 1-20 mA) in copper wire loops in order to avoid contact oxidation of contacts and splices.
A 1.8 metres (5.9 ft) power cord that can be used to allow an iPad to be used while on charge as the power cord supplied is too short for this to be easily possible in most circumstances.

Around 25 million lightning strikes occur in the United States every year, with most taking place during the summer months. The NWS reports that these strikes result in about 20 fatalities annually.
Lightning hits the United States approximately 25 million times annually. The majority of these strikes happen during the summer, causing around 20 fatalities each year, according to the NWS.
However, a direct lightning strike (such as on a radio tower antenna) will cause the shunt to arc and conduct the massive amount of electricity to ground, protecting transmitters and other equipment. Another older form of lightning arrester employs a simple narrow spark gap, over which an arc will jump when a high voltage is present.
