I just got a 510 and PCC kit from word up, and well, WORD up 
vaping is so much nicer than smoking.
Anyways, I've noticed a high pitch wining noise coming from my pcc when I plug a battery into it. The noise stops when the A light turns off and it's done charging.
It's obnoxious and it makes me worry about the safety of keeping it in my pocket.
Oddly enough I just resoldered the input jack on my friends ebike charger, and it was making the same noise! I wrote it off as a really cheap charger, which it was.
