Accepted Answer

Yes, the Surface Laptop 4 charges itself via the docking port. I use this dock daily with my Surface Laptop 4.

Answer

You're right, of course, the 199W power supply unit is the same size as the dock itself - precisely so that you can also charge the connected device. I like the docking concept: 1 plug, cable running to the back or front (rotatable), everything connected. The right solution if you need a lot of connections. Also has a disadvantage: the laptop cannot be started when the display is folded down.
What also pleases: The Surface Laptop 4 can also be charged via the USB-C port, which is advantageous, for example, for screens that also supply power and you don't need a doc.

Your data. Your choice.
