Supported Systems: macOS 10.13 or later, Windows 10/11 (Does not support Windows 8/7/XP, etc.)
⚠️ Important Notes
1、For high-power-consumption, high-performance Thunderbolt devices (e.g., eGPU docks, Thunderbolt arrays), please connect these heavy-duty devices directly to the computer! Exceeding the load will affect the normal operation of other connected devices.
2、This product is specifically designed for computers with Thunderbolt 4 ports. Please confirm your computer has a Thunderbolt 4 port first. It is NOT compatible with Windows laptops or desktops with Thunderbolt 3 ports—do not attempt to use it with such devices!
3、Customers with Thunderbolt 3 devices please purchase other Thunderbolt 3 docks available in our store.
4、When connecting monitors to the downstream ports: a maximum of 2 monitors is supported for Apple devices, and a maximum of 3 monitors for Windows devices. The number is limited by the support capacity of the computer itself.
