Tanks are an important part of vaping, this contains wire, coils and e-liquid. This is where the magic happens, e-liquid goes in and is stored, whilst vapour comes out. All tanks have a maximum capacity of 2ml due to TPD regulations, some might come with a spare glass or an extension glass that is a larger size.
Similar to a tank, rebuildables contain wires and coils, however, you can make the coil yourself by wrapping the wire and adding cotton. This is more appealing to vapers that what to go to a more advanced level of vaping as the user will require knowledge about rebuilding and coil safety. Available in many forms; RDA (Rebuildable Dripping Atomiser), RSA (Rebuildable Squonk Atomiser), RDTA (Rebuildable Dripping Tank Atomiser), RTA (Rebuildable Tank Atomiser)
