USB C Extender Adapter

This USB C Extender Adapter extends a USB Type C connection while preserving data, power and video signals. It suits users who need to place a headphone, game controller, hub, laptop or phone farther from the host port without losing functionality.

Thunderbolt 5 transfer rate 80 gbps

The adapter supports a maximum data rate of 80 Gbps and is backward compatible with Thunderbolt 4, Thunderbolt 3, USB 3.2 Gen 2 and USB 2.0. An inner E-Marker chip manages the connection for stable high-speed transfers with external SSDs or docking stations.

240W charging with LED monitor

Up to 240 W (48 V/5 A) power delivery is available when paired with a compatible PD 3.1 charger, and the built-in digital LED screen shows real-time voltage, current and power. Video output reaches 8K at 60 Hz and up to 540 Hz refresh for gaming displays, but the adapter cannot add ports or convert to other connector types.

Questions about this item

What does the 80 Gbps figure mean when I plug this adapter into my laptop?

It lets you move large files to an external SSD or docking station at the full Thunderbolt 5 bandwidth, provided both host and device support that speed.

How does the Thunderbolt 5 interface limit real-world charging and video?

The adapter passes up to 240 W at 48 V / 5 A with an E-Marker chip and carries 8K at 60 Hz or 540 Hz at lower resolutions, but only if the charger, cable and display all meet the same spec.

What physical space does this grey two-piece adapter need to fit?

Each piece is a straight USB-C male-to-female coupler, so it adds only the length of the connector itself and sits inline with any USB-C port.
