  • Product typeUSB to DisplayPort Adapters
  • Extend USB-C reach by joining two cables for charging, data or video

USB-C Coupler Pair for Thunderbolt 4/3

This two-pack provides female-to-female USB-C couplers that join two cables into a longer run. They suit users who need extra reach for charging, data or video without replacing an existing cable.

Thermals Noise and Power Draw

The aluminium alloy housing passively dissipates heat during high-power delivery up to 240W. No fan is present so operation is completely silent. Power draw depends entirely on the connected devices and the cable specifications.

Build Integration

Each coupler adds a compact inline connection tested for over 10 000 insertion cycles. It requires USB-C cables that already support video transmission for 8K 60Hz pass-through. The plug-and-play design needs no drivers and frees you from buying a single long certified cable.

Questions about this item

How do I install the USB-C female-to-female coupler, and what step do people often get wrong?

Connect two USB-C cables into each female port; the step often missed is confirming both cables support video transmission for 8K@60Hz pass-through.

What maintenance or replacement will the coupler need later?

The ports are rated for 10 000 plug-and-unplug cycles; replace the unit once the ports become loose or the LED indicator no longer lights.

What limit appears first under sustained use?

The 240W power delivery ceiling is reached before the 40Gbps data or 8K@60Hz video limits during heavy charging loads.
