Coils are responsible for heating the e-liquid in your e-cig and turning it into vapour. In strict terms, a vape coil is a wire wrapped in a spiral shape around your e-cig wicking material. Then it's fitted in place in its e-cig atomizer head, the coil connecting the positive part of your battery to the negative.
High resistance coil
An atomizer head with resistance above 1.0 ohm.Generally used at lower power and are more suited for “regular” vapour production.
