This all-powerful pack of 5x replacement Clapton coils is designed to be used with the Kanger Subtank Nano, Mino, and Toptank. Clapton coils are made using a base wire, and have a thin amount of wire wrapped around it, similar to a guitar string. This in turn significantly enhances the surface area of Kangertech vaper coils, resulting in enhanced vapour production as well as throat hit. The Kangertech vaper coils come with Japanese Organic Cotton and do better at higher wattages owing to heightened surface area.
