One cable for charging and video

The SMUGDESK USB4 cable carries up to 240W of power and 40Gbps of bandwidth in a 3.3ft length. It supports 8K at 60Hz or dual 4K at 60Hz video output. The cable works with USB4, Thunderbolt 3 and 4, and all USB-C devices.

Plug in and go

Both ends are USB-C so the cable fits any USB-C port without adapters. Data speed depends on the host port: Gen 2 ports deliver up to 20Gbps, while Gen 3 ports reach the full 40Gbps. Charging reaches 240W only when the charger and device both support PD 3.1 at 48V 5A.

Check your charger and ports

Verify that your power adapter supplies the wattage you need — common bricks are 18W, 65W, 100W, 120W, 140W or 170W. Confirm the host port is USB4 or Thunderbolt 3 or 4 for maximum bandwidth. Ensure the display accepts 8K 60Hz or 4K 60Hz over USB-C before ordering.
