I got my EGo from Puresmoker yesterday......I charged it for a few hours just to be sure. I started vaping at around 2 pm yesterday....it's 11:40 am and this thing hasn't died yet. I vape about 2.5 ML a day. Is that normal for a 650 batt? I read it would maybe last me 6-7 hours. I wonder if they could have possibly gave me the 1100 instead. Either way, I'm not complaining, amazing batt life!
