Uwell Crown 4 IV Tank

Considering the incredible reputation developed over the years by its predecessors, it’s fair to say that Uwell’s Crown IV Tank has an awful lot to live up to - and it sure does deliver on all accounts.

Constructed by stainless steel and pyrex glass, the Crown IV tank offers a revolutionary patented self-cleaning technology, meaning that it can absorb e-liquid that has trickled through to the condensation holder and vaporise it, significantly reducing potential juice leakage that will have otherwise gone to waste.

The tank also features a 2ml capacity, top filling design and a bottom adjustable airflow system, alongside new double helix coils that produce an exceptional standard of flavour and offer a longer expected life span by utilising higher quality steel that can be found as standard in luxury watches.
