Now I will tell you - if you have a busy life schedule - you either need 4 78mm batts with two chargers or 2 78mm batts with one X2 and let it charge while you are on the computer typing and vaping (like I am doing right now)... Charging times and busy schedules sometimes get in the way of each other. It is not good to charge any batt while you sleep or you are out and this rule makes two chargers necessary...
