The Vapolution Vaporizer kit operates on 12VDC which equals safety and portability. A travel adapter included in the kit makes sure you and your vaporizer will not have to be far apart even on camping trips or other excursions. The vaporizing system includes 2 different size bowls to please those looking for the most efficient vape possible and those seeking a robust vapor puff. In addition to the bowl size variety, temperature control allows the individual to choose the rate of vaporization. Above and beyond all else, this is the only true glass on glass vaporizer. No metal screens, no aluminum heating elements.
