I live in the US, but I'll soon be travelling to Prague and Vienna. I'll need to be able to recharge my phone (Motorola Droid), netbook (Asus Eee PC 1000), and camera battery (for a Canon 7D) while I'm there. The camera battery charger says
Input: AC100-240V 50/60Hz
The netbook charger says
Input: 100-240V~1A 50-60Hz.
And the Droid charger says
Input: 100-240V~1A 50-60Hz 0.2A
Am I correct in thinking that I will only need an adapter for these plugs, such as this one
? Or will I need a converter as well?
