Another advantage of bigger devices is that it allows for different heating methods to be implemented, which can change the quality of the resulting smoke. Petite vape pens need to rely on a conduction heating system, where the material is heated through direct contact with a heating element. This produces a vapor that is less smooth than what can be produced using other methods.

I remember being confused by the same thing when I got into vaping. As you can imagine, a bigger device gives manufacturers more options on what kind of features you can give the device. But what exactly are the differences?
