Using your V3i kit couldn't be easier. Simply inhale from the cartomizer end and the battery will heat the liquid without any buttons being pressed, and will stop when you finish inhaling.

To charge your batteries, remove the cartomizer from the battery and then screw the battery into your PCC or the USB charger. If using the PCC, hold down the button on the back for a few seconds, and the row of lights above your e cigarette will come on, these lights will stay red but will count up to show how much charge is in your V3i battery.
