Larger devices than e-cigarettes, Mods (short for modified) are known for their high vapor production. They are described as modified (Mod for short) because they have certain extra features that a regular vape pen does not have. For advanced vapers a Vape Mod can give enhanced performance. A typical mod will feature a built-in battery, digital screen to read off settings and plenty of power packed into a small package. If you’re a beginner we advise you start with a more simple vape pen.
