Coiled USB 4.0 cable for high-speed workflows

This 3.9ft coiled USB 4.0 Type C cable delivers bidirectional 40Gbps data transfer and 240W power delivery. It supports 8K@60Hz video output for monitors or dual 4K displays. The spring spiral design keeps desks tidy while connecting laptops, smartphones, tablets, docking stations and game consoles with a single male-to-male cord.

Replaces slower legacy cables when bandwidth matters

Upgrading from USB 3.0, 3.1 or 3.2 cables is worthwhile when moving large files or driving high-resolution displays. Actual read speeds reach 2.8GB/s and write speeds 2.1GB/s, moving 2.5GB in roughly one second. The cable is backward compatible with earlier USB C standards, though performance matches the lowest common denominator of the connected devices.

Fits compact setups needing power, data and video

The coiled construction extends to 3.9ft and retracts to save space on crowded desks or in bags. It requires a host and peripheral with USB Type C ports that support the needed protocols for full 40Gbps throughput, 240W charging or 8K video. Plug-and-play operation means no driver installation for monitors, projectors, docks, storage drives or peripherals.

Questions about this item

What connector style does the 3.9 ft coiled cable use for the 40 Gbps link?

The cable has male-to-male USB Type C connectors on both ends, with a straight plug on one side and a left-right angled plug on the other.

How do I orient the angled USB-C plug so the 240 W charge and 8K 60 Hz video work reliably?

Insert the right-angle connector with the bend pointing away from the port’s cable-relief area; forcing it the other way can stress the socket and drop the 40 Gbps signal.

When should I expect the spring-coil tension or the 48-pin contacts to need replacement?

The copper conductors and 48-pin USB-C interfaces are rated for thousands of insertions; replace the cable only if the coil no longer retracts or if charging drops below 240 W.
