The Kit has two coil options to suit different styles of vaping.
S1 Mesh, a mesh constructed 0.6ohm coil, designed for low nicotine content eliquid, a mouth to lung coil but the draw is looser and produces more vapour. You can also take restrictive Direct To Lung draws with this coil.
N1, a traditional style coil with 1.2ohm resistance, designed for use with higher nicotine eliquid or Nicotine Salts . These give a tighter draw which use less power.
These OBS coils are for use with the Mini tank only.
