Box Mods are the larger and ‘boxier’ shaped mods that tanks are screwed into. They are bigger in size as they either house a larger and more powerful inbuilt battery or removable battery that is charged externally.
They are typically more powerful in wattage as they are most commonly used for sub-ohming, as sub-ohm vape tanks require a larger power output.
