Model USB4

  • 40 Gbps data transfer moves large files quickly
  • 240W PD 3.1 charging powers laptops and high-draw devices
  • Single 8K at 60 Hz or dual 4K at 60 Hz video output
  • Backward compatible with Thunderbolt 3, 3.2, 3.1 and 2.0
  • Built-in safety resistor keeps current stable at 5A

Cable purpose and length

This 3.3 ft USB4 cable carries data, video and power over a single USB-C connection. It is built for users who need a short, high-bandwidth link between a host and a peripheral.

Who should use this and who should not

The cable suits creators moving large project files, professionals driving one 8K or two 4K displays, and anyone charging power-hungry laptops or industrial gear at 240 W. Buyers whose devices only support USB 2.0 or 3.0 speeds, or whose USB-C ports lack DisplayPort Alternate Mode, will not gain the advertised video or throughput benefits.

The spec that decides fit

The 40 Gbps data rate is the single figure that determines whether the cable matches the workload; both host and device must support USB4 or Thunderbolt 3/4 to reach that throughput.

Questions about this item

Does my laptop need a Thunderbolt 4 or USB4 port to get the 40 Gbps data rate?

Yes. The cable delivers 40 Gbps only when both host and device support USB 4.0 or Thunderbolt 4; otherwise it falls back to USB 3.2, 3.1, 3.0 or 2.0 speeds.

Will the cable charge my older USB-C laptop that only accepts 100 W?

Yes. It supports PD 3.1 at 48 V / 5 A for 240 W and is backward compatible with PD 3.0, so it will safely negotiate 100 W or 60 W with older devices.

How can I verify the cable is running at 40 Gbps after I plug it in?

Check the OS connection speed — it should show 40 Gbps for USB4 or Thunderbolt 4 — and confirm large-file transfers approach 2500 MB/s.
