It has an input port -C/TB4, and an output port -A and 3x-C/TB4 output.
It is impossible to call this solution a full-fledged "docking station".
From my point of view, a full-fledged docking station should have an RJ45 port of at least 5Gbps, 3-4 USB-A, optical SPDIF In/Out and 1-2 HDMI/DP.
And this is the simplest 3xusb-c splitter. Those. For this "dock" you will have to buy another one at a higher price to get real expansion of the output ports on poor be ports(only -c) laptops that don't have them, including Apple products.
That is, the price of this garbage is at least 3 times higher.
