Hello. I'm not new to vaping but I have a question. Yesterday i got a 650mah ego-c upgrade and with it came a standard usb charging cable. I use a 5V 1000mah wall charger I got a while ago. The problem is the usb connector on the battery heats up a little. It's just warm, not hot but I recently read about exploding batteries, burnt out wall warts and it kinda scared me. I bought ego-c so I can vape while it charges, but is it safe? Shoud I use my phone's 5V 850mAh wart instead?
Thanks in advance.
