Question about Qoltec 52470

Because the normal Swiss plug (type 13) with its round pins is designed for a maximum of 10A. A normal Swiss socket should be permanently loaded with a maximum of 8A. This means a charging capacity of approx. 1.84kW, so if you have a car with a 70 kWh battery, you will need 38 hours to charge from 0 to 100.
The German plug is designed for 16A and may be loaded correspondingly higher.
What you must not do under any circumstances is to get one of these one-off adapters which can only handle 10A and operate this charging station on a normal household socket. At best the fuse will blow, at worst your house will burn down. Minimum would be to get an adapter to a type 23 plug which has rectangular pins, this socket can withstand 16A but even then the 80% continuous load should be maintained.
If you have to have a socket fitted either way, then install a Schuko socket directly, this is permitted as long as there is a Swiss socket next to it.

Why don't Galaxus provide an adaptor for the non-Swiss plug?
