1.5 ft USB4 cable for 240 W charging

This 1.5 ft USB4 cable connects USB-C devices and delivers up to 240 W of power at 48 V and 5 A. It supports Thunderbolt 4 and is backwards compatible with Thunderbolt 3, USB 3.2, USB 3.1 and USB 3.0. The cable handles 8K or 6K video at 60 Hz on a single display, or dual 4K monitors when two cables are used.

Suits users needing maximum power

Ideal for owners of MacBook Pro, MacBook Air, iPad Pro, iPad Air and similar USB-C laptops or tablets who want full 240 W charging and 40 Gbps transfers at a desk. Not for users who require a longer reach between devices, or builders who need an optical cable for runs beyond the length supplied here.

No bundled accessories or software included

The package contains only the cable itself. There are no adapters, docks, carrying cases or driver discs. All charging, video and data capabilities depend entirely on the host device, charger and display supporting the relevant USB4 or Thunderbolt specifications.

Questions about this item

My laptop only has USB 3.2 ports — will this cable still deliver 240 W charging and 40 Gbps data?

The cable is backwards compatible with USB 3.2, 3.1 and 3.0, but the 240 W (48 V / 5 A) and 40 Gbps rates only activate when both host and device support USB4 / Thunderbolt 4.

I plan to keep my older Thunderbolt 3 dock — can I run an 8K display through this cable?

Thunderbolt 3 is limited to 40 Gbps and typically caps video at 4K / 60 Hz; to reach 8K / 60 Hz you need a Thunderbolt 4 or USB4 host and display.

After plugging everything in, how do I confirm the link is running at 40 Gbps?

Transfer a large file between two high-speed drives; sustained read speeds near 2.8 GB/s and write near 2.1 GB/s show the 40 Gbps lane is active.
