The Vape Mod is a vaporizer pen that originated from a lack of functionality and battery power in the earlier vaporizer pens. They were underpowered and offered subpar battery life and vape volume. Some creative individuals started tinkering with objects lying around the house, like flashlights and other electronics and combine these common household items with the vaporizer pens and created soaped-up Advanced Personal Vaporizers (APVs) that had extra battery power and more functionality. This trend caught on with the vaping communities and the manufacturers saw the market potential and began producing professional versions of the modded vape pens. These became known as vape mods, mechanical mods or mostly by the term mod or APV. Today, the mods are much better than the earlier crafty garage devices, as are the eGo style vape pens and other vape pens much better today due to the advances in vaping and lithium battery technology.
