Different USB-C cables may support different protocols or ways of transferring data, such as MHL, HDMI, Thunderbolt 3, and DisplayPort.
USB 2.o
USB 2.0 has been around since 2000. Although not the most common, it is still present in some USB-C cables or adapters, typically the USB-A to USB-C class. This supports data transfer speeds, maxing out at 480 Mbps. Additionally, charging speeds will be slower, with 5 volts at 0.5 amps for a maximum output of 2.5 watts.
USB 3.0
USB 3.0 is identified as the third major version of the USB standard for interfacing computers and electronic devices. It adds the new transfer rate called SuperSpeed USB that can transfer data at up to 5 Gbps, which is about ten times faster than the Hi-Speed (maximum for USB 2.0 standard).
USB 3.1 (also referred to as USB 3.1 Gen 1 & USB 3.1 Gen 2)
The USB 3.1 is the successor to USB 3.0. It usually comes with a bright turquoise port. The USB 3.1 Gen 1 also supports up to 5 Gbps, while the USB 3.1 Gen 2 doubles the transfer speed of 3.0 to 10 Gbps. In addition, the USB Power Delivery 2.0 makes a big step forward as well with up to 100W of power.
