Camera Labs

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

The netbook charger says

And the Droid charger says

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?

Most power supplies are universal input, such as those ones. So yes, a mechanical adapter is all you need.

Instead of that everything to everything adapter, you might be able to get smaller ones if you're only going to specific places that use the same sockets.

Thanks, popo, and good point. The specific adapters seem to be both smaller and cheaper. I think this pack of adapters seems like it will do the trick.
