How to use

Connect the dock to a compatible host device using the integrated USB‑C connector.

Attach external peripherals, storage devices, or displays to the dock’s available ports as needed. Ensure the host device supports the relevant USB‑C modes (data, power delivery, and display output where applicable) for full functionality.

Recommendations

Use a USB‑C charger rated for the laptop’s required wattage to achieve full 100 W pass-through charging. For optimal data transfer speeds, connect devices that support USB 3.2 Gen 2 and use quality cables. Verify host device compatibility with USB‑C power delivery and alternate modes (such as DisplayPort over USB‑C) before relying on display output or high-wattage charging.
