What this adapter does and who uses it

A USB-C extender that carries data, power and video through a single Thunderbolt 5 compatible connector. It suits professionals and gamers who need to extend a USB-C link without losing throughput or charging speed.

How it fits into a build

The adapter sits between a host port and a peripheral, adding reach for docks, hubs, external SSDs, headphones or game controllers. It requires a USB-C or Thunderbolt host and a compliant cable on each side, freeing the user from cable-length limits while preserving bidirectional traffic.

Capacity and headroom

Rated for 80 Gbps transfer and up to 240 W power delivery at 48 V / 5 A when paired with a matching charger, it drives 8K at 60 Hz or high-refresh panels up to 540 Hz. An integrated E-Marker chip and PD 3.1 support maintain stability, while the onboard display shows live voltage, current and power. It will not add bandwidth beyond the host or device limits.
