    Mine does. I was just curious if everyone else's is the same? It's a faint buzzing noise that continues for about 4-5 seconds even after unplugging it from the wall w/o anything charging on it.

    If this isn't normal behavior I should probably stop using it, lol.

    Mine did... don't recall it happening more than once, though.

    "did" as in it never happened again?

    I haven't checked but, as a rule, all such devices (transformers) buzz to one degree or another. I just picked up the power brick attached to my wife's Dell notebook and held it to my ear; the buzz is very distinct at that distance.

    From all the posts relating to this, everyone seems to also notice it buzzing for a couple seconds even after you unplug it from the wall

    I would probably put it down to the lack of insulation. Wouldn't be too worried about it

    Mine does this too, although only if the USB cable is not plugged into the wall adapter. Odd, but I'm fine with it.
