Am I the only one this is happening to?

wondering if its because i bought it in the USA (110v) and i'm using it in Portugal (240v) - i know the charger is auto switching but it shouldnt be making noises....

I should have mentioned that your Nokia charger is probably fine. What you are hearing is normal for this type thing (unless it is so loud you can hear it across the room).

It may be louder at 240V than at 110V. I am at 110V and I had to put my AC4U directly up against my ear to hear what you described. At 240V the filter caps in the photo above have much more energy stored in them than when the AC4U is plugged into 110V. It makes sense to me that if there are sounds coming from the transformer they would be more pronounced when the AC4U is connected to 240V.
