Double Battery Devices

Most Vape Devices use rechargeable batteries. A battery supplies power for the coil to heat the E-Liquid which creates vapour. Some Vape Kits have Built-in-Batteries (charged via USB), however most Box Mod Vapes consist of external batteries which can be removed and charged externally. Common battery types are 18650, 20700, & 21700 with varying capacities that focus on higher power output and a larger battery capacity to last longer whilst vaping.
