The higher the number, the newer the generation of USB. Mostly it means they have faster data transfer speeds and can output more power when charging devices.

    They're revisions to the USB standard. USB stands for "Universal Serial Bus." In the before times there used to be different connectors and formats for sending data over wires for a lot of things. Eventually USB came along and solved a lot of problems all at once: https://simple.wikipedia.org/wiki/USB
