A vaping device is an electronic, battery-powered device that heats e-liquid to produce a vapour that can be inhaled.
It follows a simple process: the atomiser (the part that produces the vapour) is contained in the tank that has a tiny electric heating coil, wrapped around a wick. When you draw on the device, e-liquid is heated to form vapour that is then inhaled.
Design of vaping devices has evolved thanks to rapidly rising demand and new technologies, particularly in the latest generation of products.
Digital displays and components that allow more experienced users to customise temperature and airflow are now common.
