What this cable does

This USB Type C extension cable adds 3.3 feet of reach between a host and a peripheral. It carries data, power and video through a single male-to-female connection. The two-pack suits users who need extra length at a desk and another for travel.

Speed and power limits

Data moves at up to 10 Gbps under USB 3.1 Gen2, so a 5 GB file transfers in roughly 5 to 10 seconds. Charging reaches 100 W at 20 V and 5 A when both the charger and the device support that rate, and the cable also works with QC 3.0. Video output tops out at 3840 by 2160 at 60 Hz or 2K at 120 Hz.

The deciding specification

Video and 10 Gbps data only function when the host port, the cable and the display all support USB 3.1 Gen2 or Thunderbolt 3. If any link in the chain is limited to a lower generation the extension will fall back to slower speeds and no video.

Questions about this item

Will this 3.3 ft cable work with my existing Thunderbolt 3 dock and laptop?

Yes, the cable is compatible with Thunderbolt 3 and USB 3.1 Gen2, supporting 10Gbps data, 100W charging, and 4K@60Hz video when both host and dock support those modes.

How can I verify the cable is delivering 10Gbps speeds and 100W power after connecting it?

Check the OS link speed shows 10Gbps and use a USB PD meter or the laptop's battery settings to confirm 20V/5A charging; video should run at 3840x2160@60Hz without flicker.

The pack includes two male-to-female cables — do I need any extra adapters for 4K@60Hz video?

Each cable is USB C male to female; for 4K@60Hz you must also use a USB-C Gen2 host cable and a monitor that accepts video over USB-C, otherwise video will not pass.
