The Thunderbolt 3 (USB-C) Cable is a cable produced by Apple to allow the transfer of data with supported Thunderbolt 3 and 4 devices, the display of video on Thunderbolt displays, or to be charged from a USB-C Power Adapter, sold separately.



Teardown of Apple Thunderbolt 3 (USB‑C) Cable (0.8 m)

The Thunderbolt 3 (USB-C) Cable was first released in December 2017 as a 0.8-meter version. It also supports fast charging with up to 100 watts of power.[1][2]

Differences with USB-C cables[]

Apple's own USB-C Charge Cable looks externally similar to, and is longer than, the Thunderbolt 3 cable. It can also be plugged into Thunderbolt 3 and 4 ports (denoted by a Thunderbolt symbol), but its data transfer speed would be limited to that of USB 2.0 (480 Mbps). The USB-C cable also does not support carrying video signals. To achieve maximum bandwidth of up to 40 Gbps (an 80-fold improvement), a genuine Thunderbolt 3 cable would be required.[3]
