USB-C Coupler for Thunderbolt 4 Devices

This two-pack provides female-to-female USB-C connections for extending cables or joining devices directly. It works with Thunderbolt 4, Thunderbolt 3, USB4 and USB 3.2 hosts including laptops, tablets, phones and consoles. No drivers are required and the reversible plugs accept either orientation.

Sustained 240W Charging and 40Gbps Throughput

The coupler supports Power Delivery 3.1 up to 240W (5V/3A to 20V/5A) continuously, not just in brief bursts, allowing full-speed charging of high-power laptops during long sessions. Data moves at up to 40Gbps across the link, so large project transfers maintain line-rate speed without throttling. An integrated LED shows real-time charging status.

Thunderbolt 4 and USB4 Interface Limits

The adapter passes 8K video at 60Hz and 40Gbps data only when both connected hosts and cables meet Thunderbolt 4 or USB4 Gen 3 requirements. With USB 3.2 Gen 2 or Gen 1 hosts the link falls back to 10Gbps or 5Gbps respectively, and video output follows the host's DisplayPort alternate-mode capability. It does not add SATA or other protocols beyond the native USB-C alternate modes.
