Can I Use My Power Bank in Switzerland?
Yes — with an adapter.
Your device handles this country's voltage, but the plug shape is different. You need a plug adapter to fit the sockets here. A plug adapter only changes the shape — it does not change voltage, and that's fine in this case because your device already supports the local voltage.
The short answer
A power bank's wall charger is dual-voltage (100–240V) — a plug adapter is all you need. Note airline rules: power banks fly in carry-on only, usually under 100Wh (~27,000mAh).
Switzerland runs 230V at 50Hz. Switzerland runs 230V at 50Hz with the unique Type J socket, which also accepts the Europlug (Type C). Many generic "Europe" adapters do not fit recessed Swiss sockets — buy a Type J adapter.
