Expanding wired network access via Gigabit Ethernet in office environments
Charging power-hungry laptops and AI-ready devices using 140W Power Delivery passthrough
This device may not be suitable for older computers that lack USB4 or Thunderbolt support, as full display and data transfer speeds require modern interface standards. Additionally, standard base-model M1, M2, or M3 Mac computers may not support dual external displays natively through this hub.

Connect an appropriate high-wattage USB-C power supply to the hub's power delivery input port to charge your laptop during operation without needing additional wall adapters.
What to consider before purchase
Verify that your host laptop features a compatible USB4 or Thunderbolt port to achieve full functionality
Check your specific macOS processor model, as standard M-series non-Pro/Max chips have limitations with dual external displays
Ensure your external power adapter supports sufficient wattage if you intend to utilize the 140W power delivery passthrough feature
Usage recommendations: Position the mini dock on a stable desk surface with adequate airflow around the housing to maintain optimal thermal performance during data transfers and high-power charging sessions. Disconnect all cables safely through your operating system before unplugging the hub to prevent data loss on connected external storage drives.
