Thunderbolt 4 USB-C cable delivers 100W charging, 40Gbps data and 8K video over 6.6ft

Cable Length 6.6 Feet

  • Charges up to 100 W with compatible power sources
  • Transfers data at 40 Gbps theoretical maximum speed
  • Drives one 8K display at 60 Hz or dual 4K displays at 60 Hz
  • Works with Thunderbolt 3, Thunderbolt 4, USB 3.2, USB 3.1 and USB 2.0 devices

Universal Thunderbolt 4 Cable

This 6.6ft cable carries Thunderbolt 4, USB4, Thunderbolt 3 and legacy USB-C signals at up to 40Gbps. It supports 100W charging and drives one 8K display at 60Hz or two 4K displays at 60Hz. The single cable replaces separate data, video and power leads for compatible hosts and peripherals.

Host Port Requirements

Before ordering, verify that your host USB-C port supports Thunderbolt 3 or 4, USB4 or at least USB 3.2 with DisplayPort Alternate Mode for video output. A plain USB 2.0 or USB 3.2 port without Alt Mode will not pass a display signal. The charger must also deliver up to 100W over USB Power Delivery to reach the cable's maximum charging rate.

Bundled Capability Impact

The 40Gbps bandwidth enables theoretical transfer of a 2.5G file in one second, with real-world reads up to 2.8GB/s and writes up to 2.1GB/s. The 100W rating covers virtually any USB-C device from phones to gaming laptops when paired with a compatible charger. No extra software or drivers are required beyond the host operating system support.

Questions about this item

Does the 6.6ft cable include a power adapter or do I need to buy one separately?

The cable delivers up to 100W (20V/5A) when paired with a compatible charger; the charger itself is not included.

Should I choose this 40Gbps version or a slower cable for my Thunderbolt 3 dock?

This cable runs at 40Gbps and is backward compatible with Thunderbolt 3, USB 3.2 and USB 2.0, so it covers the fastest and the older speeds in one lead.

Will the 40Gbps rating actually give me 2.8GB/s reads on my laptop?

The supplier states real-world speeds up to 2.8GB/s read and 2.1GB/s write, though the final rate depends on the host and storage device.
