I have already bought the same model and can help you further.
On the question of compatibility with Swiss plugs: Yes and no. Two-pin plugs (type C) fit directly into the power station. Three-pin Swiss plugs (type J), on the other hand, do not - at least not without tools.
I got myself an adapter that has a German (Schuko) plug at the front and a Swiss socket at the back. With this adapter, a three-pin Swiss plug also works without any problems on the Powerstation - I have tried this myself several times.
One more note: Although you can see three sockets in the product photos, two of them are sealed. I don't know why exactly - probably a requirement in connection with Swiss standards. In fact, you only have one socket available.
I solved this by connecting my adapter to the one available socket and using a power strip with several Swiss connections. This makes it very easy to bridge the gap - it works perfectly.
