Two purple USB-C male-to-male adapters side by side

Brainwavz

Brainwavz USB C Male to Male Adapter 2 Pack Purple 40Gbps 100W 8K@60Hz

SKU CH-QH8D-EXVHH

Two USB-C male-to-male adapters deliver 40 Gbps data, 100 W charging and 8K 60 Hz video for Thunderbolt devices

  • TypeUSB to DisplayPort Adapters
  • 40 Gbps data transfer moves large files in seconds
  • 100 W power delivery charges laptops and phones at full speed
  • 8K video output at 60 Hz connects high-resolution displays
  • Two purple adapters extend or couple USB-C cables
  • Works with Thunderbolt 4 and 3 devices

Two-Pack USB-C Coupler

This two-pack of USB-C male-to-male adapters connects two Type-C devices directly for data, video and power. Each unit meets the USB 4 standard with up to 40 Gbps transfer speed and supports 100 W power delivery. The compact design adds no bulk to a cable run.

Replaces Full-Function Cables

Use these couplers instead of carrying a long USB-C cable when you only need to join two short ones. The jump is worth it when you want 8K at 60 Hz video pass-through and 100 W charging without signal loss. Performance still depends on the host devices and cables used.

Suits Travellers With Multiple Type-C Devices

Ideal for users linking a laptop to a dock, monitor or phone while charging at full speed. Not for buyers who need a female port, an angled connector or a single longer cable. Also unsuitable if your devices only support lower USB speeds.

Questions about this item

Does the adapter need any extra clearance around its USB-C connectors to fit side-by-side ports?

The adapter is a straight male-to-male coupler with no protruding body, so it fits directly into adjacent USB-C ports without additional clearance.

What is the correct way to seat both ends so the 40Gbps link and 100W charging negotiate properly?

Insert each male plug fully until the connector clicks; partial insertion often falls back to lower speeds and prevents the 20V/5A power contract.

When should I replace the pair if the 8K@60Hz video signal becomes unstable?

Replace the adapters if repeated re-seating and cable swaps do not restore a stable 8K@60Hz picture, indicating worn contact springs inside the couplers.
