It is fully compatible with Mac. You simply need the "DisplayLink Manager", which makes it fully compatible.

that should be the case. I have a ThinkPad L13 Yoga Gen. 2. everything works

Yes, exactly, to use several screens on one notebook, you need a docking station. The Lenovo one is equipped for this. But it's not worth buying something cheap, because the cheap models often only have 2 x 1920 x 1080 pixel HD resolution, so it's worth buying something right. And this model would also come with an external power supply unit, which you could use to charge the notebook.
