USB-C to USB-C Cable Connects 2 USB-C Devices, Including MacBooks and Smartphones This three-meter USB Type-C to Type-C cable allows you to connect one USB-C device to another. For instance, a laptop to a docking station, your smartphone to a wall charger, or a hard drive or flash drive to a computer or tablet. The USB-C to C cable is compatible with any device with a USB-C or Thunderbolt 3 port, including MacBooks, Ultrabooks and Chromebooks. PD Charging Cable Produces up to 100W for Rapid Syncing and Charging The Power Delivery cable provides power output up to 5 amps (100 watts), which is sufficient for fast-charging, syncing and powering most large-capacity devices, including the MacBook Pro. It also supports USB 2.0 data transfer rates up to 480 Mbps. The USB Type-C to USB Type-C cable is backward compatible with previous USB generations, allowing you to use it with older equipment. Reversible USB-C Connectors Attach in Either Direction Unlike traditional USB cables that connect in only one direction, the reversible USB-C male connectors plug into a USB-C or Thunderbolt 3 port in either direction for a fumble-free connection every time.
