0.5 m USB-C cable for 10 Gbps data

This half-metre cable links two USB-C devices at USB 3.2 Gen 2 speed. It delivers up to 100 W of Power Delivery 3.0 current for laptops and phones. Thunderbolt 3 compatibility extends its use to docks and high-resolution displays. The short length suits desktop or travel setups where clutter is unwanted.

10 Gbps ceiling and DisplayPort 1.4 Alt Mode limit

The USB 3.1 Gen 2 interface caps throughput at 10 Gbps, so faster USB 3.2 Gen 2x2 or USB4 hosts will not exceed this rate. DisplayPort Alt Mode supports 8K at 30 Hz, not higher refresh rates or dual-stream configurations. Thunderbolt 3 hosts operate at their native 10 Gbps USB tunnel speed, not full 40 Gbps Thunderbolt bandwidth. Power Delivery negotiation stops at 100 W, so devices needing more must use a different cable.

Nickel-plated connectors

Male-to-male USB-C plugs feature nickel plating for corrosion resistance. The thermoplastic elastomer jacket survives 4 000 bends and 10 000 mating cycles in lab testing. Aluminium-Mylar foil with braid shielding reduces electromagnetic interference. The 0.5 m reach keeps connectors close, reducing strain on ports during daily connect-disconnect routines.

Questions about this item

Should I choose the 0.5m cable or a longer length for my desk setup?

The 0.5m length suits tight spaces and portable use; longer cables are available if you need more reach between devices.

What does the 10Gbps rating mean when I connect an external SSD?

It supports USB 3.1 Gen 2 speeds so large file transfers run at up to 10Gbps when both host and drive support that rate.

How does the Thunderbolt 3 compatibility affect what I can plug in?

The cable works with Thunderbolt 3 ports at 10Gbps for data, carries DisplayPort 1.4 Alt Mode up to 8K 30Hz, and delivers up to 100W Power Delivery 3.0 charging.
