FAQs

What is the maximum data transfer speed of this cable?

This USB4 cable supports a maximum data transfer rate of 20Gbps (USB4 Gen 2x2).

Can this cable power my laptop?

Yes, the cable supports USB Power Delivery (PD 3.0) up to 60W, which is sufficient for many high-performance laptops, including Apple M-series MacBooks, provided your charger and laptop support it.

What video resolutions and refresh rates does it support?

It supports DisplayPort 2.1 Alternate Mode, allowing for up to 4K at 120Hz, or dual 4K at 60Hz, with support for DSC (Display Stream Compression).

Is this cable USB-IF Certified?

Yes, the cable is USB-IF Certified, ensuring it meets the standards for reliable USB4 performance and compatibility.

What is the length of the cable?

The cable is 3 meters (approximately 10 feet) long.

What is the jacket material?

The cable features a durable and flexible Thermoplastic Elastomer (TPE) jacket.

Does this cable work with Thunderbolt 3 or 4 devices?

While USB4 is based on the Thunderbolt 3 specification, this cable is specifically certified for USB4 standards. It may work with Thunderbolt 3/4 devices, but full compatibility and performance are best guaranteed with USB4 devices.

Troubleshooting

Device not charging or charging slowly

Ensure both the cable and your power adapter support USB Power Delivery (PD) up to 60W. Verify the USB-C port on your device supports PD input. Try a different USB-C PD charger and ensure the cable is fully plugged in.

No video output or incorrect resolution/refresh rate

Confirm that your source device (laptop) and display support DisplayPort 2.1 Alternate Mode and the desired resolution (4K 120Hz). Ensure the cable is fully connected at both ends. Try connecting directly to the display if using a dock.

Slow data transfer speeds

Verify that both the host computer and the peripheral device support USB4 or at least USB 3.2 Gen 2x2 (20Gbps). If connecting to older devices, speeds will be limited by the older standard (e.g., USB 3.0 speeds).

Intermittent connection or disconnection

Ensure the cable connectors are clean and free of debris. Check for physical damage to the cable. Try the cable with different devices to isolate the issue. Ensure the cable is not being stressed or pulled.

Pros and Cons

Pros

  • Offers high 20Gbps data transfer speeds for demanding tasks.
  • Supports advanced video output (4K 120Hz) for professional visual applications.
  • Provides up to 60W Power Delivery for charging high-performance laptops.
  • USB-IF certification ensures reliability and compatibility.
  • The 3-meter length offers excellent flexibility in workspace setup.
  • Durable construction with a TPE jacket and robust connectors.

Cons

  • Maximum capabilities require a host and device that fully support USB4 Gen 2x2 and DP 2.1 Alt Mode.
  • The 20Gbps speed is lower than the maximum theoretical speed of some newer USB standards (e.g., USB4 Gen 3x2 at 40Gbps).
  • Primarily designed for USB-C to USB-C connections, not backward compatible with older USB-A ports without an adapter.
  • The cable's specific features might be overkill for users with basic charging or data transfer needs.

Setup, Compatibility & Care

Setup: This cable is plug-and-play. Simply connect the USB-C end of the cable to your USB4 or USB-C enabled device and the other end to your peripheral, display, or docking station. Ensure both the host device and the peripheral support the desired features (e.g., 4K 120Hz, 60W PD) for optimal performance.

Compatibility: The cable is designed for USB4 devices, offering backward compatibility with USB 3.2, USB 3.1, and USB 2.0 devices, though speeds will be limited to the slowest device in the connection. It supports DisplayPort Alternate Mode (DP Alt Mode) via its USB-C connectors.

Care: To maintain the cable's integrity and performance:

  • Avoid sharp kinks or excessive bending.
  • Store the cable loosely coiled when not in use.
  • Keep the connectors clean; use a dry, lint-free cloth if necessary.
  • Do not expose the cable to extreme temperatures or moisture.
