USB4 cable with Thunderbolt 4 and 240 W charging
This USB4 cable delivers up to 240 W of power through USB PD 3.1 and moves data at 40 Gbps. It suits users who need fast charging and high-speed transfers for laptops, monitors and storage devices. The 1.64 ft length keeps a tidy desk connection.
Limits of the USB4 and Thunderbolt 4 interface
Actual data speed depends on the host, the peripheral and the cable length, so 40 Gbps is the ceiling, not a guarantee. Video output tops out at 8K at 60 Hz or dual 4K at 60 Hz, and HDR at 4K 120 Hz requires display and GPU support. The cable is backward compatible with USB 3.2, 3.1 and 3.0, but speeds drop to those standards.
Check your setup before ordering
Verify that your device’s USB-C port supports USB4 or Thunderbolt 4 for full 40 Gbps bandwidth and 240 W charging. Confirm the monitor accepts 8K 60 Hz or dual 4K 60 Hz over a single cable. Ensure the 1.64 ft reach fits the distance between your ports.
