I'm assuming the Mac Mini power-supply (which I've heard is external) doesn't have a 110V/220V switch. So if I take a Mac Mini with me from the US to the EU, do I need to buy a new power-supply for it? Or is there an easier way?
My mini power supply, which is external (sometimes referred to as a brick), says '100-240V 50-60 cycles', which means you need the proper plug adaptor to hook it directly into the country's electrical system you use.
Ah, so I just need the right connector? This isn't by any chance the same as the one on the Airport Express is it? Because if it is then I already have one.
If you can plug the mini's power cable into the adapter you already have, and that adapter will plug into an outlet in the country you are going, then yes, it's the right one.
If the mini's plug won't fit it, or it won't fit a power outlet in the country you are visiting, then no, it isn't the right one.

If you have the World Travel Adapter kit from Apple, then no, that adapter won't work. The adapters included in that kit will work with the small, white square AC adapters used by an iPod charger, iBook, PowerBook or the AirPort Express directly. They won't work with any other kind of plug.
