USB Type A, USB Type C, vs. Micro USB B: What’s the Difference?

Accepted Answer

USB Type-A is the original USB connector that most people are familiar with. You probably can see USB Type-A ports on your TV, laptop, PC, and game console. USB Type-A connectors are supported in a USB version, including USB 1.1, USB 3.0 (USB 3.2 Gen 1), and USB 3.1 (USB 3.2 Gen 2).

USB Type C is a relatively new interface that was introduced in 2014.   The USB 3.0 (USB 3.2 Gen 1), USB 3.1 (USB 3.2 Gen 2), USB 3.2 (USB 3.2 Gen 2x2), and USB4, the latest revision to the USB specification are, all use this port. It is designed to solve many of the old USB Type-A port issues. Nowadays, almost every new laptop, tablet, or phone has USB Type C connectivity. It can not only be used to transmit data but deliver power as a single cable.

Micro-USB Type B is a relatively old USB standard specified connector that appeared in 2007. The USB interface is designed to connect devices like MP3 smartphones, MP3 players, GPS devices, digital cameras, etc. Like standard USB, the micro-USB series is plug-and-play and hot-swappable and was designed with a 5-pin group. Most micro–USB Type B ports use 3.0 technology at speeds of up to 5Gbps.

The latest generation USB Type C has transfer speeds up to 20Gbps. This can increase to 40Gbps with the new USB 4 variation. In comparison, older USB Type-A can only attain speeds up to 20Gbps if it uses the latest 3.2 technology.
