USB-C extension cable for USB 3.2 Gen 2

This 20-inch male-to-female cable adds length between a host and a USB-C or Thunderbolt 3 peripheral such as a dock, smartphone or laptop. It carries data at up to 10 Gbps and delivers up to 60 W of Power Delivery charging. The nickel-plated connectors and PVC jacket are rated VW-1 for flame resistance.

10 Gbps data rate with 60 W Power Delivery

The cable is certified for USB 3.2 Gen 2 speeds of 10 Gbps, twice the bandwidth of Gen 1, while simultaneously providing 20 V at 3 A (60 W) to charge the connected host. Backward compatibility lets it work with older USB generations at their native speeds.

Plug-and-play installation with no software required

Simply connect the male end to the host port and the female end to the device cable; the link negotiates automatically. The only common issue is attempting runs longer than the 0.5 m length, which this cable does not support.
