The Dragon-Lite Portable Herbal Vaporizer uses AA Rechargeable Batteries. Incredibly easy to use! Once you've finely ground your aromatic herb such as spearmint, eucalyptus, or even tobacco, fill the bowl, drop a battery into the compartment, and squeeze the sides: a light will appear in the bowl and the screen will heat immediately. This Kit contains a Dragon-Lite Vaporizer, the Battery Holder, a Cleaning Brush and an Acrylic Stem. Dragon-Lite is manufactured to the highest level of craftsmanship and materials, providing years of trouble free operation. Dragon-Lite provides a lifetime warranty.
