Compact .5m Thunderbolt 4 extension

This .5m USB-C female extension cable adds reach between a host and Thunderbolt 4 peripherals such as docks, hubs or portable SSDs. It carries power, data and video through a single connection while keeping the desktop tidy.

240W PD3.1 charging with low heat

The cable supports PD3.1 power delivery up to 240W, allowing rapid charging of compatible laptops without noticeable warmth during normal use. No active cooling is required and operation stays silent.

Sustained 40Gbps data and 8K@60Hz video

Under continuous load the link maintains 40Gbps throughput for large file transfers and drives an 8K display at 60Hz without throttling. Full performance depends on the host and peripheral both supporting Thunderbolt 4, PD3.1 and video output.

Questions about this item

How do I install the .5m Thunderbolt extension cable without losing 40Gbps speed?

Plug the male end directly into the host Thunderbolt 4 port and the device into the female end; avoid adding extra adapters or daisy-chaining another cable, which can drop the 40Gbps link.

What maintenance will the reinforced connector joints need over time?

Inspect the strain-relief collars periodically for cracks; keep the .5m cable routed loosely without sharp bends, and replace the cable if the jacket shows splitting or the connectors become loose.

What limit appears first when running 240W PD3.1 charging continuously?

The host or device thermal throttle typically activates before the cable’s 240W rating is reached, so sustained full-power charging depends on the connected equipment’s cooling.
