What it is

This is a 3.9ft coiled USB 4.0 Type C cable with male connectors at both ends. It carries 24 pins and supports 40Gbps data transfer, 240W power delivery at 48V 5A, and 8K video at 60Hz. The spring-spiral construction keeps excess length tidy on a desk or in a bag.

Who it suits

Creators moving large media files between a laptop and fast external storage will use the 40Gbps bandwidth. Users charging high-draw laptops or docking stations benefit from the 240W rating. Anyone connecting an 8K monitor or dual 4K displays gets the required video throughput without drivers.

Who should look elsewhere

Buyers whose devices only support USB 3.2 or earlier will not reach the cable's rated speed or power. Set-ups that need a straight, non-coiled cable for tight routing behind equipment should choose a different form factor.

Deciding specification

The single figure that decides fit is the 40Gbps data rate combined with 240W power delivery over a USB 4.0 connection. If the host and peripheral both speak USB 4.0 or Thunderbolt, the cable delivers full performance; otherwise it falls back to the lowest common standard.

Questions about this item

How can I verify the cable is delivering the full 40Gbps transfer rate after connecting it?

Check the host device's transfer utility or benchmark tool; the cable supports up to 2.8GB/s read and 2.1GB/s write speeds when paired with Thunderbolt 4/3 ports.

What comes in the box and do I need any extra adapters for 240W charging?

The package contains the 3.9ft coiled USB 4.0 Type C male-to-male cable only; no separate power adapter is included, so use a 48V 5A PD charger for maximum 240W output.

Which version should I choose if my laptop only has USB 3.2 ports?

The USB 4.0 cable is backward compatible with USB 3.2, 3.1 and 3.0 ports, so this single version works across all those standards.
