The SMOK Baby V2 S2 Coil Head is one of two high performance coils included with the SMOK Mag 100W TC Starter Kit. The S2 Coil Head has 0.15 ohm quadruple coils made of Nickel-Chromium heating material for a distinct vaping experience. This coil is rated for use between 30-70W but is recommended for best use at 45-65W for optimal cloud production and flavor enhancement. Custom made for the Stick series battery, this coil has a longer lifespan and 100% Organic Cotton Fiber. Due to extra direct wicking channels, the S2 Coil Head offers a more restricted airflow for a tight and narrow vape.
