Two-Pack U-Shape USB-C Adapter for Thick Devices

This two-pack provides 12 mm U-shaped USB-C adapters that angle the cable 180 degrees for a low-profile fit on thicker laptops and handhelds. Each adapter carries the same male and female USB-C connectors in a silver finish. They are designed for users who need a tidy right-angle connection on devices with deeper port recesses.

Simple Plug-In With Clearance Checks

Installation is a direct plug-in with no drivers required, but the 12 mm height must match the gap between the USB-C port and the device shell. Choosing the 12 mm version on a slim device leaves a loose fit, while the 7 mm version on a thick device will not seat fully. Measure the port-to-shell distance before ordering to avoid a gap or a forced connection.

Verify Device Port Capabilities First

The adapter passes up to 40 Gbps data, 240 W USB PD 3.1 charging and 4K at 240 Hz video, but only if the host port supports those speeds and protocols. Video output requires the host to provide DisplayPort Alternate Mode, which is not universal on every USB-C port. Confirm your device specifications for Thunderbolt, data rate and power delivery before purchase.

Questions about this item

How do I verify the adapter is delivering 40Gbps data transfer after connecting it?

Connect a Thunderbolt 4 or USB4 device and run a storage benchmark; sustained read/write speeds near 40Gbps confirm the link is operating at full capability.

What comes in the 201339-12mmx2 package and what must I supply separately?

The pack contains two silver 12mm U-shape USB-C male-to-female adapters; you must provide your own USB-C cables and ensure the host device supports the desired charging or video mode.

Should I pick the 12mm or 7mm version for a Steam Deck or ROG Ally?

Choose the 12mm version; the manufacturer specifically recommends it for Steam Deck and ROG Ally to provide proper clearance and port protection.
