Buzz or whine coming from LG charger (USA)

[theduder]

Anyone else notice the buzz or high pitched whine coming from the charger that comes with the N4? The sound lasts about 5 to 10 seconds after unplugging it from the wall outlet. I am in the US.

Yes, mine does the exact same thing. A sort of buzzing / rattling noise that you can hear if the room is somewhat quiet and, as you mentioned, the noise continues for a few seconds after you unplug it.

So that's what the noise is! I was wondering it was coming from.

Let us know if you have any type of fire flare up because of that whine. Thanks.

I got the same thing on the LG charger, but it dies right after you unplug the actual USB cable from it. Nothing to worry about really, and I don't notice the adapter getting any warmer than any other charger.
