Box mods can be perfect for MTL vapers as well DTL vapers due to the versatility of features and vape tanks available. Internal battery mods feature built-in batteries which are charged internally (inside the box mod). Box mods with internal batteries are easy-to-use and require no external battery chargers and can be charged through the box mod itself. All you need is a USB charger to keep your box mod topped up.
Pair your internal battery mod with a great vape tank and you're all ready to go, you don't need to purchase extra batteries like you would with an external battery mod.
