What this cable does

This USB-C extension cable carries 4K video at 60 Hz, delivers up to 240 W of power and moves data at 20 Gbps. It is built for users who need a single 1-metre link between a host and a USB-C monitor, dock or high-speed drive.

The spec that decides fit

Your source device and the display must both support DisplayPort Alternate Mode and the display must handle DP sleep mode for video to appear. The host and the target drive must each be capable of 20 Gbps transfers or the link will fall back to a lower speed.

Behaviour under sustained load

The cable is rated for a continuous 48 V at 5 A, so it maintains full 240 W charging while data and video run simultaneously. It is not suited for setups that require longer runs or higher voltages than the USB-C 3.2 Gen-2 standard allows.

Questions about this item

What does the 20 Gbps data rate mean when I plug this cable into my laptop and drive?

The cable supports up to 20 Gbps transfer, but the actual speed depends on both the host port and the storage device also supporting 20 Gbps operation.

How does the USB 3.2 Gen 2 interface limit charging and video in daily use?

The Gen 2 link caps data at 20 Gbps while allowing 240 W at 48 V / 5 A and 4K at 60 Hz, provided the charger, monitor and host all support those modes.

What clearance do I need for the straight USB-C plugs on this 1 m cable?

Each plug is a standard straight Type-C connector, so allow enough depth behind the port for the plug body plus a small bend radius for the 1 m cable run.
