It connects between your USB-B device and the USB-C or Thunderbolt 3 port on your mobile device. Transfers Data and Charges Devices at Fast USB 3.1 Gen 1 Speeds The USB Type-C to USB Type-B cable supports USB 3.1 Gen 1 data transfer rates up to 5 Gbps, which is 10 times faster than USB 2.0. The Power Delivery cable also provides power output up to 3 amps (60 watts), which is more than sufficient for charging, syncing and powering compatible devices. The cable is backward compatible with previous USB generations, allowing you to use it with older equipment.
