One Cable for Charging Video and Data

This USB4 cable carries up to 100W of power, 8K video at 60Hz and 40Gbps data in a single 3.3FT USB‑C to USB‑C link. It suits laptop owners, creative professionals and anyone who wants one lead for docking, fast charging and high‑resolution displays.

Bandwidth and Power Depend on the Port

The cable is rated for 40Gbps with USB4 Gen3 or Thunderbolt hosts, but drops to 20Gbps on Gen2 ports. Charging reaches 100W only when both the charger and the device support 20V/5A; otherwise the cable negotiates the highest level both ends allow.

Check Your Host and Display Before Buying

Verify that your computer’s USB‑C port supports USB4 Gen3 or Thunderbolt for full 40Gbps speed and 8K output. If the port is Gen2 only, expect 20Gbps bandwidth and 4K video. Dual 4K monitors require two separate cables and a host capable of driving two streams.

Questions about this item

Should I pick the 3.3FT length or a longer one for my desk setup?

The 3.3FT cable reaches 100W charging and 40Gbps data at this length, so choose it if your devices sit close together; a longer run may drop below the 40Gbps ceiling.

What does the 40Gbps headline speed actually deliver when I copy files?

Real-world reads hit 2.8GB/s and writes 2.1GB/s with a Gen3 port, while a Gen2 port caps at 20Gbps; the cable itself supports the full 40Gbps potential.

Does the Thunderbolt 4 label guarantee 40Gbps on every port?

The cable is built to the Thunderbolt 4 standard, yet the port generation decides the ceiling — Gen3 gives 40Gbps, Gen2 stops at 20Gbps, and charging always reaches 100W.
