Question about Anker Charging Base for Anker Prime

No, it's a two-pole cable on the 220v side, but it's too big for Switzerland, so you'll have to ask for a cable like Value Câble d'alimentation Fiche plate Euro vers C7 (1.80 m)
An adapter is possible but not practical in my opinion.

It needs an additional adapter...:-(((

No, the plug does not fit into our sockets. They are 2-pin but too thick and the sheathing is round.

Yes, it has the normal 2-pin plug, which works in Switzerland as well as in Europe
