What this cable does

This BUCIER USB 4.0 Type C coiled cable carries bidirectional data at up to 40Gbps, delivers up to 240W of power and drives 8K video at 60Hz. It is built for Thunderbolt 4 and Thunderbolt 3 connections between laptops, monitors, docking stations and high-power peripherals.

Who it suits and who it does not

Creators and professionals moving large media files between Thunderbolt hosts and fast storage will use the 40Gbps bandwidth and 240W charging together. Users who only need basic charging or 5Gbps data on short runs can choose a simpler, less costly cable instead.

Build integration

The 3.9ft spring spiral keeps the desk tidy while linking a laptop to a monitor, dock or power supply without driver installation. Male-to-Male USB Type C ends plug straight into host and device, freeing adjacent ports and reducing cable clutter on compact workstations.

Questions about this item

Does my laptop need a USB4 or Thunderbolt port to use this cable's 40Gbps speed and 240W charging?

Yes, the host must provide a USB4 or Thunderbolt 3/4 Type-C port that supports 40Gbps data and 48V/5A Power Delivery to reach the cable's rated 40Gbps and 240W.

Will this cable still charge and move files if I plug it into an older USB 3.2 or 3.1 Type-C port?

The cable is backward compatible with USB 3.2, 3.1 and 3.0 Type-C ports; data and charging will work but at the lower port's maximum speed and power, not at 40Gbps or 240W.

How can I confirm the link is running at 40Gbps after I connect a Thunderbolt 4 drive?

On Windows open Task Manager > Performance > select the drive and verify the link speed reads 40Gbps; on macOS open System Information > Thunderbolt and check the negotiated speed shows 40Gbps.
