thanks connman. right now i am taking an old 510 battery, a usb cord, and a dual usb car charger and trying to make a 5v passthrough for my car.. this way i could see what vaping at 5v is all about before putting the money into another mod, and have something to conserve my already long lasting batteries.. idk if im a lightweight or what, but im vaping my own mix of 20mg nic +marlB + menthol regularly, with a bit of fruit here and there.. im only going through 1 batter per almost 2 days..
