  • Outputs 4K 60Hz video over DP Alt Mode

One cable for charging, data and video

This USB C to USB C cable delivers up to 100W power delivery, 20Gbps data transfer and 4K 60Hz video output in a single 6.6ft run. It is built for users who want one lead to charge a laptop, move large files and drive an external display without swapping cables.

Video needs DP Alt Mode on the host port

The 4K 60Hz signal only works when the source device supports DisplayPort Alternate Mode over its USB C port. Ports limited to power or USB 2.0 data will not pass video, so the cable falls back to charging and 480Mbps transfer on those hosts.

20Gbps rating sets the speed ceiling

Maximum throughput reaches 20Gbps when both ends implement USB 3.2 Gen 2x2; otherwise the link negotiates down to the lowest common speed. Buyers whose workflows demand sustained 20Gbps should verify that their controller and storage support that generation.

Questions about this item

Should I pick the 6.6 ft cable or the 6.6 ft two-pack for my desk setup?

Will the 20 Gbps rating give me full speed on my Thunderbolt 3 SSD enclosure?

Yes, the USB 3.2 Gen 2x2 cable supports up to 20 Gbps, matching Thunderbolt 3 drive bandwidth when the host and drive both support that speed.

Does the USB 3.2 Gen 2x2 interface limit charging to less than 100 W?

No, the same cable carries 100 W (20 V / 5 A) Power Delivery alongside the 20 Gbps data lane.
