What this cable does

This Thunderbolt 4 cable carries data at up to 40 Gbps and delivers up to 100 W of power. It supports a single 8K display at 60 Hz or dual 4K displays at 60 Hz. The 1.6 ft length suits tight desk setups.

Limits of the 40 Gbps link

Full 40 Gbps throughput requires a Gen3-capable port; a Gen2 port drops the ceiling to 20 Gbps. Video and data share the same bandwidth pool, so driving dual 4K screens reduces headroom for file transfers. The cable is certified by USB-IF and supports PD 3.1 negotiation.

Check your ports before buying

Verify that both host and peripheral have Thunderbolt 4 or USB4 ports rated for 40 Gbps and 100 W charging. Devices limited to 20 Gbps or lower wattage will not reach the cable’s maximums. The short length may not reach floor-standing towers or distant monitors.

Questions about this item

Should I choose a longer Thunderbolt 4 cable or does the 1.6 ft length suit my desk?

The 1.6 ft length is ideal for tight desk setups, docking stations or portable use; if your monitor or eGPU sits farther away, a longer cable would be more practical.

What does the 40Gbps rating mean when I connect this cable to my laptop and monitor?

It delivers up to 40Gbps bandwidth, enabling a single 8K display at 60Hz or dual 4K displays at 60Hz, plus fast data transfers — actual speed depends on the host port generation.

Does the USB-IF certification and PD 3.1 support guarantee 100W charging on any USB-C laptop?

The cable is USB-IF certified for Thunderbolt 4 and supports PD 3.1 up to 100W (20V/5A); your charger and laptop must also support 100W PD to reach that maximum.
