Since I bought this speaker In the US, I'm a little concerned if it switches from 110 to 240 volt by itself? I live In Europe.
Asked by: Denis
The Marshall Acton III Bluetooth Speaker System (Black), BH # MAACTIONIII, will auto-switch for 100 to 240 VAC, 50 / 60 Hz voltage. Just adapt the North American, twin-bladed AC wall plug to your local configuration.
