Electricity & telecom

Electricity is supplied at 220V 50Hz. Outlets are the European standard CEE-7/7 "Schukostecker" or "Schuko" or the compatible, but non-grounded, CEE-7/16 "Europlug" types. American and Canadian travellers should pack a voltage-changing adapter for these outlets if they plan to use North American electrical equipment (although a lot of electronics with power adapters will work on 220 volts, check your equipment first).
