For me, it also runs with Windows without any problems.

No, it is a portable 4 port hub which gets it's power over the USB connection

With this HUB, you only achieve that USB TypeC data ports are available on a PC that only has USB TypeA data ports. This makes the device perfect. By 'data ports' I mean that I can only connect USB sticks. Mobile phones (with no charging) or external hard drives with USB-C might work, but then the power could be a problem, as the USB-A might not send enough to the C ports. It is not possible to turn a technically older (inferior) port into something better with a HUB. As far as I know, USB-C for docking / Thunderbolt / Displayport is always necessary directly on the device. There are USB-3 A docking stations with DisplayLink. However, there are restrictions on the supported resolution and the number of external displays.
