Are you leaving it plugged in over night? I found when I first got mine, I was impatient, because I noticed it was still red, but every 5 seconds or slow, a faint, quick green flash and back to red. I am talking a nano second flash of green. So the next night I left it plugged in all night, and in the morning, mine was green. I have a wall charger with a usb plug. I just found out tonight it is not good to drop the
batteries. Mine shorted out inside, will not vape or charge. light stays green and the button light on the ego just flashes. New kit on order from the UK. arg.
