Barbara, you need a converter to convert the electricity from 230 down to 110 and then an adapter for the end of your plug to make it fit into the socket. Most converters come with several different plugs for different countries but depending on what country you are in, sometimes the converter boxes don't fit into the European sockets, lol. For example, I was in France and the sockets were recessed into the walls so I couldn't use the converter box.

What I find best to use is Conair blowdryers and curling irons. They have several models that you can just switch a switch on the them that changes the 110 to 230. You can find them at any store like Walmart for under $20. Then all you need is an adapter for the end of your plug.

For items like battery chargers that don't have a converter built into them, you will need to use one or you will fry your items.

To answer the question in your subject title, I dunno :)
