What type of travel adaptor should I bring?

In the Balkans, the power plugs and sockets are of type C, the standard voltage is 220 Volts, and the frequency is 50 Hz. Check your appliances and battery chargers and make sure they are dual voltage.

Type C plug: Two round prongs (used in much of Europe, but not in the UK or Ireland).

Electricity is not always available during the challenge, so please bring portable batteries if you require electricity.
