Can AC Power adapters handle 240V input?

The supplied power adapters work with both 110 and 240 voltages but you may need a plug adapter for Spain. (Most of the world has 230/240 volts).

I think, it depends where you come from… the plug is the same in all EU countries, so maybe you need a plug adapter. If your charger allows 230V, than this is no issue as well. But if you charger is for 110V only, you do not need only an adapter, but a voltage changer as well
