Ok, I’m leaving for Ireland in a couple of days and I’m taking a laptop with a charger that fits into a normal US outlet. It says the output is 18.5 volts and the imput is 100-240 volts on the charger and it has three prongs instead of just two. I bought one converter for use with normal two prong cables to charge my phone, ipod, and camera batteries and then I also bought an additional adapter plug with surge protection that’s safe for computers. My question is this. The adapter that’s safe for computers is just an adapter, but it says on the package “you will need a converter or transformer for your single voltage appliances.” What does that mean exactly? I only have a two prong converter, not a three. Do I need a three or can I plug the computer directly into the adapter? I’m so confused.
Your US laptop runs on 110 volts, in Ireland the electricity is 220volts. If you plug in your laptop in Ireland without a converter, it will fry. You need to buy a proper transformer, and you’ll probably get a suitable one at the airport.
Ur laptop is powered by 18.7 volts provided by the step down transformer in the middle of your chord, which is capable of taking a 240volt input, which is fine for Ireland. Get a cheap adaptor in any electronic store when u get there, probably about 20 euro, but, I would still use a surge protector as the power in Ireland is at the upper end of the capacity curve of that transformer.
ur laptop will be fine cuz it can take 240 volts, which is what is used in ireland
i asked a question on this a few months ago u can go look at it if you want
