Hello All: I live in Canada and plan to visit England in the next few months. I have a D3100 with the standard kit battery charger. What sort of adapter would I need for this battery charger? Is there anything I need in addition to an adapter? Is it as simple as using something that allows for the different plugs or do I need something else to "regulate the voltage". Sorry for the silly question, but anything to do with electricity is baffling to me.
