The Micro USB Cable is a miniature version of the Universal Serial Bus (USB) interface designed for connecting small and mobile devices like smartphones, GPS devices, MP3 players, photo printers, and digital cameras. The micro versions, like standard USB, are plug-and-play and hot-swappable.
On September 12, 2012, the Lightning to USB Cable was introduced to replace its predecessor, the 30-pin dock connector. Apple mobile devices such as iPads, iPods, and iPhones use the Lightning connector to connect to host computers, cameras, external monitors, USB battery chargers, and other peripherals.
A Mini USB Cable is quite smaller than a USB Type A or B cable but twice as thick as a Micro USB cable. Mini USB and all other USB connectors are expected to be phased out in favour of USB Type C. The USB-Mini was designed to connect mobile devices such as MP3 players and cameras, and it is a much smaller connection, allowing smaller devices to connect.
When it comes to the debate between micro USB and mini USB, even standard micro USBs have a data transfer rate of at least 480 Mbps. Higher-end micro USBs, on the other hand, support data transfer speeds of up to 5G bps, outperforming the mini USB cable. Micro-USB was once the most common type of USB port, and it can still be found on many older models.
