A vape mod or Mechanical Vape Mod is simply a vape pen on steroids. Its a much bigger, more powerful vape pen. It has more functionality than a vape pen and was designed to produce more vapor, increase the throat hit and increase the overall flavor of e juice. The Vape Pen Mod is armed with a much bigger, and bulkier, battery which produces the increased vapor production and overall flavor of your vape. It is a “modded” vape pen.
