Mini-USB is a type of connector used primarily for connecting small electronic devices, such as cameras, MP3 players, and some smartphones, to computers or chargers. It is smaller than the standard USB connector, making it suitable for portable devices where space is limited. Mini-USB connectors come in two main types: Mini-A and Mini-B, with Mini-B being the more commonly used version. Although Mini-USB was popular in the early 2000s, it has largely been replaced by the more versatile Micro-USB and USB-C connectors. These newer connectors offer improved performance and convenience, allowing for faster data transfer and easier connections.
