How to charge:

*The center pin in the battery is stretchable. If it can not work with any cartomizer/ atomizer, it may because of the poor contact of them , so you can try to use tweezers to pull up the center pin.
*Please BE CAREFUL.If you vape consistantly for a long time, the connection part of battery and atomizer/cartomizer might be too hot to be touched.
