Cable Length 3.3 Feet

Style USB4

  • Charges laptops fully in 1.5 hours with 100W power delivery
  • Transfers 2.5G files per second at 40Gbps maximum speed
  • Drives single 8K display at 60Hz for ultra-high definition video
  • Connects Thunderbolt 4 and 3 devices plus USB 3.2 3.1 3.0 gear
  • 3FT length suits desk and dock setups

One Cable for Charging Data and Display

This USB4 cable handles up to 100W power delivery at 20V/5A and reaches 40Gbps data rates with compatible hosts. It drives a single 8K or 6K monitor at 60Hz or two 4K displays using two cables. The 3.3FT length suits desktop and dock setups.

Sustained Throughput With Compatible Hosts

Real-world sequential reads reach 2.8GB/s and writes reach 2.1GB/s when both ends support the full 40Gbps lane. A 2.5GB file moves in roughly one second under those conditions. Performance scales down automatically with Thunderbolt 3 or USB 3.2/3.1/3.0 hosts.

100W Power Delivery at 20V/5A

The cable negotiates the maximum power the connected device accepts up to 100W. A MacBook Pro can reach full charge in under 1.5 hours with a suitable GaN charger. Devices that need more than 100W or use a different voltage profile will not draw their peak rate.

Questions about this item

Does the 100W USB4 cable get warm or draw extra power when charging a laptop at 20V/5A all day?

The cable supports up to 100W (20V/5A) power delivery and is designed for continuous fast charging without overheating.

What charger or port must I already have to reach the 40Gbps data rate or 8K@60Hz video?

You need a host and device that both support USB4 or Thunderbolt 4 at 40Gbps, plus a 100W-capable USB-C power adapter for maximum charging speed.

Will this cable work with my older Thunderbolt 3 dock and USB 3.2 Gen 2 devices?

Yes, the cable is backwards compatible with Thunderbolt 3, USB 3.2, USB 3.1 and USB 3.0 ports, though speeds and video modes will match the older standard.
