Micro-USB is a small, standardized connector used primarily for charging and data transfer in various electronic devices. It was widely adopted in smartphones, tablets, and other portable gadgets due to its compact size and versatility. The connector features a symmetrical design, allowing it to be plugged in either way, which enhances user convenience. Introduced in 2007, Micro-USB replaced the larger Mini-USB connector and became the dominant charging standard for many years. However, it has gradually been replaced by the newer USB-C connector, which offers faster data transfer speeds and improved power delivery. Despite this shift, Micro-USB remains common in many older devices.
