    Slovenia's plugs, and why you need an adapter from the UK

    Facts checked on

    In a nutshell

    Slovenia's plug type is the European one, officially CEE 7/16, at 230 V and 50 Hz, according to the Slovenian Tourist Board. British visitors need an adapter, as do travellers from Ireland, Cyprus, Malta, Switzerland, Liechtenstein, Denmark and other continents.

    The voltage itself suits UK appliances.

    Plugs in Slovenia, in short

    Full read: 2 min

    • European CEE 7/16 plug.
    • 230 V and 50 Hz, the same voltage range UK appliances use.
    • British visitors need an adapter.
    • Bring your own; specialist electrical shops sell them otherwise.
    What I would do

    I'd pack two adapters rather than one, or one adapter plus a small multi-port USB charger, because rooms often have few sockets by the bed. I wouldn't count on buying one at the last minute in a mountain village.

    My key points

    Before you go to Slovenia, this

    1. 01 Getting there

      European plug, 230 V

      The Tourist Board says Slovenia uses the European plug, CEE 7/16, found in most European countries, at 230 V and 50 Hz.

    2. 02 My tip

      Who needs an adapter

      According to the Tourist Board, visitors from Great Britain, Ireland, Cyprus, Malta, Switzerland, Liechtenstein and Denmark, and from other continents.

    3. 03 To save money

      Bring your own

      The Tourist Board advises bringing your own adapter, given the many socket types; otherwise, specialist electrical shops sell them.

      Coverage and radio

      Phones work throughout the country, and Radio Si broadcasts news, weather and traffic in English and German, according to the Tourist Board.

      Slovenia roaming

    Plugs in Slovenia, step by step

    1. Buy a UK-to-European adapter before you fly

      Slovenian sockets take two-pin European plugs; UK plugs won't fit without an adapter.

      CEE 7/16

    2. Check your chargers

      At 230 V and 50 Hz, UK phone and laptop chargers work fine with just an adapter.

      230 V

    3. Add a multi-port USB charger

      Rooms often have few sockets by the bed, so one adapter feeding several USB ports goes further.

    Who needs an adapter in Slovenia

    The Tourist Board itself lists the European countries whose visitors will need the appropriate adapter, Great Britain, Ireland, Cyprus, Malta, Switzerland, Liechtenstein and Denmark, and adds that travellers from other continents need one too. For a trip from Britain, then, put an adapter on the packing list straight away; it’s the one item that’s hard to improvise without. Everything else that goes in the case is in what to pack for Slovenia.

    What I’d pack anyway

    Beyond the adapter, a small extension lead or a multi-port USB charger solves the problem of rooms with few sockets, especially if several of you are charging phones, watches and cameras. In mountain huts in Slovenia, charging may not be as easy as in a hotel, so a power bank helps on long routes. To stay connected on the trip, check your roaming deal first, as I explain in Slovenia roaming.

    Where to get one

    Because there are so many plug types around the world, the Tourist Board suggests everyone brings their own adapter. If you forget, it says specialist electrical shops sell adapters for most other European plugs and for American ones. I wouldn’t count on finding one late at night in a mountain village, so if your first night is in a Julian Alps valley, sort it before you leave.

    Once your dates are set, check which hotels are still free in Ljubljana before prices climb.

    Voltage and devices from outside Europe

    At 230 V, devices bought in the UK work normally once plugged into an adapter. If someone in your group brings appliances from outside Europe, as well as the adapter it’s worth checking the label on the charger or device, which shows the voltage range it accepts. If 230 V isn’t included, an adapter isn’t enough and you’d need a converter.

    The car radio

    The same Tourist Board page that covers plugs has a useful tip for drivers. Radio Si, the foreign-language channel of RTV Slovenija, gives news, weather and road reports in English and German, the road reports every hour and, at the height of summer, more often. You’ll find it on FM 91.1, 93.4 and 102.8. The page also notes that the national channels, Radio Slovenija 1, Val 202 and Ars, carry some foreign-language information, and that in July and August the weather forecast goes out in English, German and Italian on all three after the main news.

    If you would rather have a local show you round, book a guided tour in Ljubljana and choose by the reviews.

    Once your dates are set, check which hotels are still free in Ljubljana before prices climb.
