0.5 m USB-C 2-pack for charging and data

This 2-pack contains two USB-C to USB-C cables, each half a metre long. They support USB 3.2 Gen 2 data rates up to 20 Gbps when both host and device use the same generation. Power Delivery 3.1 allows up to 240 W charging with compatible adapters. An E-Mark chip protects connected equipment during high-power sessions.

Suits single-port laptops needing 4K video

Users who want one cable to drive a 4K 60 Hz display while delivering up to 240 W will find these suitable. They also work with Thunderbolt 3 and 4 ports for video and data. Builders who need longer reach, angled connectors or legacy USB-A ends should look elsewhere.

20 Gbps requires USB 3.2 Gen 2 at both ends

The headline data rate is only achieved when each side of the connection supports USB 3.2 Gen 2. Plugging into older ports falls back to lower speeds automatically. Check your device specifications before relying on maximum throughput.

Questions about this item

Does the cable maintain 20 Gbps transfer speed during long file moves?

The 20 Gbps rate requires both connected devices to support USB 3.2 Gen 2; otherwise the link falls back to a lower speed.

Does the cable or its E-Mark chip get hot when delivering 240 W continuously?

The integrated E-Mark chip manages power delivery up to 50 V at 5 A and protects both the adapter and the device during sustained charging.

Must both host and display have USB-C video-out to use the 4K 60 Hz feature?

Yes, 4K at 60 Hz output works only when the source and the monitor both provide USB-C or Thunderbolt video-capable ports.
