FAQ

  • Q: What is USB Type-C?
  • USB-C is a type of USB connector that is capable of supporting the following:
    ■ Data transfer speeds up to 10Gbps, if you use USB 3.1.
    ■ Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
    ■ Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).

    If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth.

    Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers.
