FAQs

What is the maximum data transfer speed of this cable?

This USB4 cable supports a maximum data transfer rate of 20Gbps.

Can this cable support 4K resolution at 120Hz?

Yes, it supports a single 4K display at 120Hz or dual 4K displays at 60Hz using DisplayPort 1.4 Alt Mode with DSC.

What is the maximum power delivery this cable can handle?

The cable supports up to 60W of Power Delivery (USB PD 3.0) when used with a compatible charger or dock.

Does this cable work with older USB standards like USB 3.0 or USB 2.0?

Yes, it is backward compatible with USB 3.2, USB 3.1, and USB 2.0 devices, but performance will be limited to the capabilities of the older standard.

What does 'USB-IF Certified' mean for this cable?

USB-IF certification means the cable has been tested and meets the strict standards set by the USB Implementers Forum, ensuring reliable performance, safety, and full compatibility with USB4 specifications.

Is the 3-meter length suitable for long-distance connections?

The 3-meter (10-foot) length is ideal for extending reach across a desk, connecting to rear ports, or for setups where devices are not placed close together. It is designed to maintain signal integrity over this distance for its specified performance levels.

How can I identify the cable's specifications instantly?

Each connector on the cable is laser-etched with USB4 specifications, providing quick and easy identification of its capabilities.

Troubleshooting

No connection or slow data transfer

Ensure both the connected devices and the ports support USB4 and the desired speed (20Gbps). Try a different USB4 port on your device. Verify that the peripheral device is also capable of USB4 speeds. Restart your computer and the peripheral device.

Display not working or showing low resolution/refresh rate

Confirm that your host device and monitor support 4K@120Hz or dual 4K@60Hz via DisplayPort Alt Mode. Check if Display Stream Compression (DSC) is enabled on your graphics card or device settings if using higher resolutions/refresh rates. Ensure the monitor is connected to the correct port on the cable.

Device not charging or charging slowly

Verify that the connected USB-C power adapter or dock provides at least 60W of power. Ensure the E-marker chip in the cable is functioning correctly by testing with another compatible charger. Check your device's charging settings and ensure it supports USB PD up to 60W.

Cable feels warm during use

A slight warmth during high-data transfer or charging at 60W is normal due to power and data flow. However, if the cable becomes excessively hot, disconnect it immediately. This could indicate an issue with the connected device or power source. Ensure the cable is not covered or in an enclosed space restricting airflow.

Pros and Cons

Pros

  • High data transfer speeds (20Gbps) for efficient workflows.
  • Supports advanced video resolutions and refresh rates (4K@120Hz).
  • Provides up to 60W Power Delivery for charging laptops.
  • USB-IF certified for assured compatibility and performance.
  • Extended 3-meter length offers greater flexibility in setup.
  • Durable construction designed for frequent use.

Cons

  • Requires compatible USB4 host devices and peripherals to achieve maximum speeds.
  • The white color might not suit all aesthetic preferences or environments.
  • While backward compatible, older USB standards will limit performance.
  • Higher resolution/refresh rate video output may require compatible DisplayPort Alt Mode support.

Setup, Compatibility & Care

Setup: Simply connect the USB-C end of the cable to a USB4-compatible port on your host device (e.g., laptop, docking station) and the other USB-C end to your peripheral device (e.g., external drive, monitor, charging adapter). Ensure both the host device and the peripheral support the desired features (e.g., USB4 data, DP Alt Mode, Power Delivery) for optimal performance.

Compatibility: This cable is designed for USB4 devices and is backward compatible with USB 3.2, USB 3.1, and USB 2.0, though performance will be limited to the capabilities of the slowest connected device. It supports DisplayPort 1.4 Alt Mode, HDR10, and USB Power Delivery up to 60W. For full 20Gbps data transfer and 4K@120Hz video, both the source and destination devices must support these specifications. It is ideal for high-performance laptops like Apple M-series MacBooks and other USB-C laptops.

Care: The cable features a durable TPE jacket and nickel-plated connectors. To maintain its condition, avoid sharp bends, kinks, or excessive force on the connectors. Clean the connectors gently with a dry, lint-free cloth if needed. Store the cable loosely coiled rather than tightly wrapped to prevent internal wire damage.
