Compatibility check

Verify that both host and peripheral support USB4 Gen 3×2 or Thunderbolt 3/4 to reach the rated speed and power. Confirm the charger and device can negotiate PD 3.1 EPR for 240 W; lower wattages such as 140 W, 100 W or 60 W are also supported.

Questions about this item

Does the 1.5 ft cable include a power adapter or must I buy a 240 W charger separately?

The cable itself is rated for 240 W PD 3.1 power delivery; a compatible 240 W charger and a device that accepts 240 W are required and sold separately.

Should I choose this 1.5 ft length or a longer option for a desktop docking setup?

At 1.5 ft the cable is intended for short, tidy connections between a laptop and a dock or monitor on the same surface; longer runs would need a different length.

What does the 40 Gbps rating mean when I plug the cable into a Thunderbolt 4 dock?

With a Thunderbolt 4 host and dock the cable supports the full 40 Gbps bi‑directional bandwidth for data, video up to 8K 60 Hz and power up to 240 W simultaneously.
