Thunderbolt 4 Certified USB4 Cable

This 1.5 ft cable carries Thunderbolt 4 certification and supports up to 40Gbps data transfer and 240W power delivery. It connects any USB-C or Thunderbolt device with a single reversible plug. The short length keeps desks tidy while maintaining full bandwidth.

Suits single 8K or dual 4K display users

Creators who need one 8K@60Hz monitor or two 4K@60Hz screens will get the required throughput. Builders without Thunderbolt 3, USB4 or USB-C ports cannot use the cable. Buyers who need longer reach for docking stations or wall-mounted displays should look at something else.

Fits Thunderbolt 4 and USB4 docks

Plug the cable into a certified dock or eGPU enclosure to free up laptop ports for peripherals. It delivers up to 240W to charge gaming laptops while driving high-resolution displays. The 1.5 ft span works best when the host and dock sit side by side on the same surface.

Questions about this item

What charger and device do I need to reach the 240W 48V 5A rating?

You need a USB PD 3.1 charger and a device that both support 240W (48V/5A) charging; the cable will then deliver the maximum power the device allows.

Will I get 40Gbps throughput when I connect this cable to my Thunderbolt 3 dock?

Thunderbolt 3 ports are limited to 20Gbps, so the link will run at up to 20Gbps rather than the cable’s 40Gbps ceiling.

How can I confirm the link is running at 40Gbps after I plug it in?

On Windows open Device Manager and check the USB4/Thunderbolt controller speed; on macOS use System Information to verify the link shows 40Gbps.
