Vape pens can also go by any other names; vapor pens, vaporizer pens, or vape pen mods. But why are they called ‘pens’? Well, the first vape pens actually resembled cigarettes and were called cig-a-likes or e-cigarettes. However, eventually, manufacturers realized they needed to incorporate larger batteries and more power, so they started making larger devices that were more cylindrical and pen-shaped.
Vape pens are used for vaporizing e-liquid, wax, or dry herb and are powered by a small battery that connects to a tank or atomizer that contains a heating coil system. Then when the battery is fired or engaged, it will heat the coil, which in turn heats the e-liquid (wax or dry herb) and produces vapor.
