Cable Length 6.6 Feet

Style USB4

  • Charges laptops at up to 100W in 1.5 hours
  • Transfers data at 40Gbps with Thunderbolt 4 support
  • Drives 8K displays at 60Hz for sharp visuals
  • Works with Thunderbolt 3 and USB 3.2 devices
  • 6FT length gives flexible desk placement

One Cable for Charging Data and Display

This USB4 cable carries up to 100W of power and 40Gbps of data while driving an 8K display at 60Hz. It replaces separate charging, dock and video cables for USB-C laptops and tablets. The 6.6FT length suits desk or meeting-room setups.

Bandwidth and Power Depend on the Host

The 40Gbps rate and 100W delivery are only achieved when both host and peripheral support USB4 or Thunderbolt 4. Older USB 3.2, 3.1 or 3.0 ports will fall back to their own lower speed and power limits. Dual 4K output requires two separate cables.

40Gbps Certified USB4 Performance

The cable is rated for the full USB4 40Gbps specification, enabling 2.5GB file transfers in one second under ideal conditions. If your workflow needs only 20Gbps or 60W charging, a lower-spec cable will also work. Buyers who need Thunderbolt 3 certification or longer runs should verify compatibility first.

Questions about this item

Should I choose the 6.6FT length for my desk setup?

The 6.6FT length gives enough reach for most desk-to-dock or laptop-to-monitor runs without excess cable clutter.

What does the 40Gbps rating mean when I copy large files?

Real-world speeds reach up to 2.8GB/s read and 2.1GB/s write, so a 2.5GB file transfers in about one second.

How does the Thunderbolt 4 compatibility affect what I can plug in?

The cable works with Thunderbolt 4, Thunderbolt 3, USB3.2, USB3.1 and USB3.0 devices, capping at each device's maximum supported speed.
