Standard USB | The standard USB port is present on most laptops and desktops. Most USB devices connect to the computer using this port. |
Mini‑USB | A mini‑USB port is used in small electronic devices such as cameras, external storage drives, tablets, and so on. |
Micro‑USB | A micro-USB port is smaller than mini-USB port and is used in phones, tablets, wireless headphones, and other small electronic devices. |
Powered USB | A powered USB port uses a more complex connector than a standard USB. It essentially has two connectors in a single cable, one for standard USB plug and the other for power, thus allowing higher-power devices to be connected without the use of an independent power supply. It is used in retail equipment such as barcode reader and receipt printers. |
