Europe is on 230 v and the wall outlets are different from other places in the world, however, the same all over Europe. Make sure your appliance (shavers, hairdryers, curling irons, camera charges, laptops, etc.) have a switch to change the voltage to 230! If not, you will need a converter (not recommended for electronics). Also, make sure that you have the proper plug to use in Europe. These are often available in airports, luggage stores, and electronic stores ... outside of the Czech Republic. Please come prepared! The plugs are not readily available here!
