Key Features

• USB4 and Thunderbolt compatible: Works with USB4 and is compatible with Thunderbolt 4 and Thunderbolt 3 so it fits a wide range of modern laptops and docks.
• 40Gbps data transfer: Supports up to 40Gbps for large file transfers and fast backups when both ends support the speed.
• High-resolution video: Can drive 8K@30Hz or 5K@60Hz displays, or dual 4K@60Hz monitors, making it useful for creative work and multi-monitor setups.
• 100W charging capacity: Delivers up to 100W (20V/5A) so it can reliably charge most laptops while transferring data and video.
• Backward compatibility: Works with USB 3.1, USB 3.0 and USB 2.0 devices for broader day-to-day connectivity.

Who It's For

This cable is best for professionals and enthusiasts who use modern Windows or Mac laptops with USB-C or Thunderbolt ports and need one cable for charging, display output and fast file transfers. It's also suitable for owners of docks, monitors or external SSDs that support Thunderbolt or USB4 speeds.

It is less suited to users with only legacy USB-A devices or those who never need display output; if your devices do not support DisplayPort Alt Mode or USB4/Thunderbolt speeds, you will not see the full benefit and could opt for a simpler USB-C cable instead.
