USB4 cable delivers 40 Gbps data, 240 W charging and 8K video in a 5 ft length

Cable Length 5 Feet

Model USB4

  • Transfer large files in seconds at 40 Gbps
  • Drive an 8K display at 60 Hz or dual 4K at 60 Hz
  • Deliver up to 240 W of power with PD 3.1
  • Withstand up to 5000 bends in lab tests
  • Works with Thunderbolt 3 and Thunderbolt 4 hosts

High-speed connectivity

This USB4 cable delivers 40Gbps data transfer and up to 240W power delivery through a USB-C to USB-C connection. It supports 8K@60Hz or dual 4K@60Hz video output and maintains backward compatibility with Thunderbolt 3 and 4 standards. The 5ft length suits desktop and mobile setups requiring maximum bandwidth.

For high-bandwidth workflows

Creators moving large media libraries and professionals driving high-resolution displays will benefit from the full 40Gbps throughput and 240W charging. Users with older USB 2.0 or 3.0 ports will not reach these speeds, and devices lacking PD 3.1 support cannot utilise the maximum power rating.

The 40Gbps certification

This single specification determines whether the cable matches your hardware capabilities. Both host and peripheral must support USB4 or Thunderbolt 3/4 to achieve the rated transfer rate and video performance. Without that support, the link falls back to lower speeds.

Questions about this item

Does the 5 ft USB4 cable include a power adapter or only the cable itself?

The box contains one USB‑C to USB‑C cable; a PD 3.1 charger capable of 48 V at 5 A must be purchased separately to reach the 240 W rating.

When should I choose this 40 Gbps USB4 cable over a slower USB 3.2 or Thunderbolt 3 lead?

Pick this cable when your host and device both support USB 4.0 or Thunderbolt 4 and you need the full 40 Gbps bandwidth for 8K 60 Hz video or 2500 MB/s file transfers.

What does the 240 W figure mean when I plug the cable into a real laptop?

It means the cable can carry up to 48 V at 5 A, so a compatible PD 3.1 charger will deliver 240 W to power‑hungry laptops, while the built‑in safety resistor keeps current stable at 5 A.
