The EU version did not include the EU/CH plug adapter. You have to ask for the adapter separately when ordering.
I have fitted a CH plug myself :-)

It was supposed to be there, but wasn't.
But it was delivered by Galaxus the next day (free of charge) without any problems and at a stretched gallop.

Thank you.

No, the EU version does not come with an adapter. But changing the plug is the better option anyway.
