At swisschage.ch you only pay for the charging processes.
Where can I see the charging prices?
The prices vary from charging station to charging station. You can see the applicable prices for each charging station in the app. We recommend that you check the applicable prices in the app before each charging process - even if you start the charging process with your charging card.
Even at roaming stations, you pay exactly the prices that are displayed in the app - no roaming charges are added.
