Ireland uses a large Type G power outlet with three square prongs. Ireland’s standard voltage is 230V and 50Hz frequency. This is different from the voltage in the US, which uses 120 volts, so you’ll need to use an adapter to plug in your electronics while in Ireland. A Universal Adapter is your best bet and will allow you to plug in all your American electronics in Irish power outlets. We also recommend using this particular adapter because it works in over 100 other countries around the world, so you’ll be able to use it for future travels, too.
