USB4 cable for high-speed workflows

This four-foot USB-C to USB-C cable carries the USB4 specification and reaches 40 Gbps data rates when both host and device support that speed. It targets creative professionals and power users who move large media libraries between workstations and external storage.

Single-cable dock replacement

The cable delivers up to 240 W (48 V / 5 A) of USB Power Delivery, letting a compatible GaN charger power laptops, tablets and phones without a separate brick. It also drives one 8K display at 60 Hz or two 4K displays (each requiring its own cable), freeing desk space by combining charging and video in one link.

Headroom for current and near-future gear

Rated for 40 Gbps throughput, the link handles uncompressed 8K/60 Hz or 4K/144 Hz streams and sustained large-file transfers. It is backward compatible with Thunderbolt 3, USB 3.2, USB 3.1 and USB 3.0 hosts, though speeds and power drop to the older standard's limits. Builders needing longer runs or active optical lengths must look elsewhere.

Questions about this item

Does the 240 W power rating hold up during hours of continuous charging?

The cable supports up to 240 W at 48 V and 5 A when paired with a compatible charger; it is rated for 5000 bend cycles in lab tests.

How much heat or noise does the cable produce when running at full 40 Gbps throughput all day?

The cable itself is passive and generates no noise; heat depends on the connected charger and devices, not on the cable.

What charger and host port do I already need to reach the advertised 240 W and 40 Gbps?

You need a USB-C charger delivering 48 V at 5 A and a host port that supports Thunderbolt 4 or USB4 40 Gbps.
