Voltage of new Mac Mini (2009) Power Adapter

Ok, I took my mac mini with the power adaptor that has a 100-120v specification to an electrician. He checked out the output flow, and there you have it, it was exactly at 18.5v with 220v input! Why apple decided to put a 100-120v specification on an adaptor that clearly supports a 220v input here in Turkey, I will never know... I don't think they even know... These are my personal findings of course, make your own judgement. Just as a side note, I met 2 other people that have mac mini's that were purchased in US, and have the same power adaptor with 100-120v specs, and they have been using it without a problem for a month already... Crossing fingers and hoping it won't fry! 🙂

I also bought it one from New York 5th Avenue retail store. The reference of the part is A1188 611-0568.
I've used an adaptor, plugged it in and it has been working just fine from that moment.

No problem so far for me either.

Just bought three days ago in Florida a new mac mini 2009 with the power adapter stating on its case 120V, the instruction manual says 120-240V.

Now it's running now here in my home in Italy with 230V 50Hz without any problem, just using the plug adaptor.

I confirm that the mac mini power adaptor (a1188 611-0568) works well in Europe while the specs on the brick clearly states 100v-120v only.

I bought an 09 mac mini from the apple store in florida a couple weeks back, I'm scared to use it because of the brick, I think i'll just try it now some people have confirmed it as working, I do have a stepdown convertor but it's a huge industrial thing so don't fancy having to have that running all the time. The model number is the same as the guy who bought his from new york, perhaps it could be a misprinted batch?

I had the same concern because I travel back and forth to France with my Mac Mini. I called Apple the day the Mac mini arrived which was May 22 2009 to request an adapter similar to the previous models because it contradict what it is stated on the specs online and the printed manual.
I had a Mac Mini since the G4 and this never an issue.
They created a case number and told me to go to the closest Apple store.
An assistant manager acknowledged the difference an was surprised to see it, he told that there is nothing they could do about an exchange and that I neede to call Apple directly.
I called Apple again, the technician was not aware of the problem like the first one I talked to she was very nice but told me that could not request an exchange for an adapter of the previous model. I asked to talk to somebody who has this power. A man talk to me telling me that I just need an adapter for the plug I told him that I was concerned by the rating of 100v-120v of the imput, he made me feel like a lunatic because he also told me that he never heard of such a problem.
After telling me that Apple cannot do the exchange in the Us since the hardware has a one year warranty an Apple reseller could do the exchange in France which I find hard to believe (I hope I am wrong).
Let's hope Apple will address this situation.

Correction:
I had the same concern, I travel back and forth to France with my Mac Mini.
When I got my Mac Mini this was the first thing I checked because onetime an adapter for a Netgear router I brought from the US almost caught fire (it did not say 110v 240v on it.
I called Apple the day the Mac mini arrived which was May 22 2009 to request an adapter similar to the previous models because it contradict what it is stated on the specs online and the printed manual.
I had a Mac Mini since the G4 and I was able to plug it anywhere in the world with the appropriate plug adapter.

Like some of you, I just want to be sure I can use this Mac Mini anywhere I travel that's all

Just bought a Mac mini from San Francisco 2 days ago. Had the same A1180 110W power supply that says 100V-120V, but pluged it in 230V UK power socket, and I can confirm it works.

I also confirm that 100-120v brick works with 220v. Bought Mac Mini in Seattle, works great in Moscow, Russia with 220-240v outlets. The brick even didn't get hot after about an hour of work.

Hi to all of you who is afraid to use their US power-brick elsewhere,

I would like to share with you my yesterday's experience, and confirm that my mac-mini (which I have purchased in the US, and has a 110-120V power-brick) works just fine in Israel under 220-240V AC input.

I was tribally afraid that the power-brick would not resist the foreign voltage, but before I've plugged it to the mac, I measured the output voltage using a Digital Voltage meter, and fortunately, it was 18.36V, just the voltage that I have prayed to retrieve. I connected the mac to its power-brick and turned it on. This was only a short try, and it seemed to be working just fine. I Hope It won't let me down.

(Please do your own judgment...)

The power brick was made by Delta Electronics, a Taiwan company.

I have the same concern too. I suggest that someone ask Delta directly.

I have now purchased a 2.0GHz Mac Mini (2009 model) in both the UK and the USA (both in Apple's own retail stores) and can confirm that the power brick that came with the UK model was labeled as being rated for 110-240V, and that the power brick that came with the US model was labeled as being rated for 110-120V. This is very annoying for those of us that travel a lot and necessitated my buying a second worldwide PSU from Apple whilst in Europe.

For the record, Nokia do the same with the bundled power supplies for their phones. The European models are worldwide capable (110-240V), the US ones are US (110V) only 😟

You are right! Many people made a big mistake. They think their Mac mini can boot when they plug 110V power brick into 240V plug. It looks like fine, but it's hurting their power brick ever since anyway.

Make sure you have a world-wide power brick before using it.

I also confirm that 100-120v brick works with 220v. Bought Mac Mini in New York, works just fine in Norway with 220-240v outlets. What I don't understand, is whether this is dangerous or OK or whether the print on the adapter is simply wrong.

I confirm that my mac mini, bought in the US works in Germany (220V) ALTHOUGH it says 100-120v on the power supply. I asked some guys who know about electronics. They say either it fries at once or you'll be good. It didn't fry so I guess it works. They also said that most modern power supply should be able to handle at least 240v.

Oh and I called Apple Germany. They said it will work, although they wouldn't guarantee it. So please Apple, some official word would be nice...
