Basically, Vapage and CIG2o's are simple, when you breathe in, the E-cigarette vaporizes the flavoring and turns it into an enjoyable vapor.
go into more depth, the CIG2o/Vapage battery (the main piece) contains a
battery, a microprocessor, a vacuum switch and a small light. On the
other end, a cartomizer is attached. A cartomizer is a small unit that
has a heating coil and small flavor reserve. When you breathe in, the
battery heats the coil to about 110 degrees, vaporizing the flavoring
and glycol, this fog is what the user breathes.
