Cable Length 1.6 Feet

  • Charge devices up to 240 W with a compatible power source

High-Power USB4 Cable

This 1.6 ft USB4 cable delivers up to 240 W of power and 40 Gbps bandwidth between two USB-C ports. It supports single 8K displays at 60 Hz or dual 4K outputs at 60 Hz, making it suitable for docking stations, external GPUs and high-resolution monitors. The cable is new and rated for 48 V at 5 A.

Suits Thunderbolt 4 and USB-C Ecosystems

Users who need maximum charging speed for laptops, rapid transfers with high-capacity SSDs or 8K video output will benefit from the 40 Gbps link. Builders who require longer reach for desktop routing or permanent in-wall installations should look at something else because the fixed length is only 1.6 ft.

40 Gbps Bandwidth Decides Compatibility

The single specification that determines fit is the 40 Gbps data rate, which enables 8K video, dual 4K displays and full Thunderbolt 4 throughput. Ports limited to 20 Gbps will halve the available bandwidth, so verify that both host and peripheral support the higher tier before purchasing.

Questions about this item

Does the cable get warm when delivering 240 W continuously?

The cable is rated for up to 240 W (48 V / 5 A) charging; normal operation at that level may produce some warmth but stays within USB-IF thermal limits.

What charger and device must I already have to reach 240 W?

You need a USB-C power adapter and a host device that both support USB Power Delivery 3.1 at 48 V / 5 A.

Will this cable work with my older Thunderbolt 3 dock?

Yes — it is backward-compatible with Thunderbolt 3 ports, though bandwidth will be limited to the dock's 20 Gbps or 40 Gbps capability.
