Vape mods produce more vapor than standard vape pens, which allows for an improved throat hit and stronger juice flavour. The two major differences between vape pens and box mods are the size and strength. Vape mods are much larger than vape pens. Mods are vaping devices that house batteries and can be used to manage how you experience vaping. There’s everything from the smaller single-button devices for newer users, all the way to the large sub-ohm devices for creating big clouds using a high VG ratio of e-liquid.
