What the cable does and who needs it
This USB4 cable delivers up to 240W of power and 40Gbps data transfer for laptops, monitors, hubs and SSDs. It suits users who need a single braided lead for high-wattage charging and 8K video output.
Limits of the USB4 standard it uses
The cable reaches 40Gbps only when both host and device support that speed, and 8K at 60Hz requires a compatible display. Thunderbolt 3 and USB 3.2, 3.1 and 3.0 devices work but run at their own lower limits.
Installation and common issues
Plug the USB-C ends into each port; the braided jacket resists tangling during routing. The 3.3ft length may be short for distant docks, and 240W charging needs a charger and laptop that both accept 48V at 5A.

Questions about this item
Should I choose the 3.3 ft or 1.6 ft version for my desk setup?
The product page lists a 3.3 ft cable; the 1.6 ft length appears only in the alternate description. Pick 3.3 ft if you need extra reach between a laptop and a monitor or dock.
What does the 40 Gbps transfer rate mean when I copy files to an external SSD?
You can move large video projects or backups at up to 40 Gbps, provided the SSD and the host port both support that speed.
How does the USB4 Thunderbolt interface limit real-world charging?
The cable carries up to 240 W at 48 V/5 A, so the actual charge rate is set by your laptop and charger, not by the cable.
