USB4 cable for Thunderbolt 3 and 4 setups

This 1.64 ft USB-C to USB-C cable carries USB4 traffic at 40 Gbps and supports Thunderbolt 3 and 4 hosts, docks and hubs. It delivers up to 240 W of power when both ends and the charger allow it. The short length suits desktop docking or side-by-side devices.

Plug in and work; mind the host limits

Installation is a simple USB-C connection on each end with no driver required. The cable handles 8K at 60 Hz or 4K at 144 Hz video, plus dual 4K streams, but only if the host controller and display support those modes. Power tops out at 240 W only with a compatible charger and device negotiation.

Rated for repeated bending under load

Lab testing confirms the cable withstands 5000 bend cycles without failure. The 40 Gbps data rate and 240 W power delivery are sustained specifications, not burst figures. Actual throughput and charging speed depend on the connected host, dock and power supply capabilities.

Questions about this item

How can I verify the cable is delivering 40 Gbps data transfer after connecting it?

Use a USB4 or Thunderbolt 3/4 host and device, then check the link speed in your OS or run a large file transfer to confirm throughput near the rated 40 Gbps.

What is included in the package and what must be purchased separately?

The box contains one 1.64 ft USB-C to USB-C USB4 cable. A compatible 240W charger, Thunderbolt dock, or 8K monitor are not included and must be bought separately.

Which version should I choose for 8K 60 Hz or dual 4K 144 Hz displays?

This single USB4 cable supports up to 8K at 60 Hz and dual 4K at 144 Hz over Thunderbolt 3/4, so no alternate version is needed for those resolutions.
