Four-pack USB-C coupler for multi-device setups

This four-pack of USB-C female-to-female couplers connects two USB-C 3.1 male cables or devices on each adapter. The set suits users who need several gender changers for docking stations, charging chains or video links across a workspace.

Works with USB-C 3.1 cables

Each coupler accepts USB-C 3.1 male plugs on both sides; USB 2.0 cables require a plug reversal to function. No drivers or external power are needed, so the adapters add no software overhead and leave host ports free for other peripherals.

Sustains 240 W charging and 40 Gbps data under load

The adapters deliver up to 240 W Power Delivery while maintaining 40 Gbps throughput and 8K 60 Hz video. An LED confirms link integrity during extended transfers or charging sessions, and manual testing verifies consistent operation over time.

Questions about this item

Will the 240 W power rating hold steady during long charging sessions?

The adapter is rated for up to 240 W and adjusts output to the connected device; an LED confirms the link is active.

Does the coupler get hot or draw extra power when left connected all day?

No active cooling or power draw is specified; the passive design simply passes through the host supply.

Which cables must I already own for the 40 Gbps and 8K 60 Hz video to work?

You need USB4 or Thunderbolt 3.1 male cables on both sides; USB 2.0 cables require reversing the plug orientation.
