Most laptops typically require around 60W of power for normal operation. For gaming laptops with higher power consumption, it's recommended to provide 85W or more power. 
Tests have shown that the ACASIS 21-in-1 40Gbps Docking Station can consistently provide up to 90W power delivery, meeting the needs of all users. For laptops or tablets that require less than 90W, the 40Gbps dock  will only supply the wattage required by your device.

With this 40Gbps dock, Windows computers can connect up to 2 displays using 2 USB4 ports (or 1 HDMI port and 1 USB4 port), supporting dual-screen display with resolution up to 4K@60Hz. It can also be used as a single-display dock.

On Macs (with Intel, M1/M2/M3 Pro/Max CPUs), you can expand your desktop to two screens using any combination of HDMI and USB4 ports. Macs equipped with M1/M2/M3 CPUs only support one external display.

With just one ACASIS 21 Ports 40Gbps Dock, transform your cluttered desk into a clean, tidy workspace.

The ACASIS 21-in-1 40Gbps Docks works with USB-C computers, including Apple M2, M1, M1 Pro, M1 Max, M1 Ultra, Intel based Macs, Windows PCs, Linux, and Chrome OS devices. It is also compatible with the new USB-C iPhone 15 and 15 Pro, and tablets including iPads and Windows tablets that feature USB-C.
