All Aspire clearomizer tanks and eGo atomizers would not work without using BDC coils, BVC coils or wicks, they are an absolutely essential component. By applying heat, an electric current, or a combination of the two, the atomizer is similar to your standard household vaporisers in many ways, in that it allows liquids to be transformed into a vapour. The clearomizers are screwed onto the battery, and when the heat is applied, voila! You have a working e-cigarette which can now be inhaled to your heart's content. We offer a huge range of Aspire tank clearomizers and eGo tanks. You can purchase Aspire Coils including the BVC and BDC coils for all models on the site.
