The Uwell Crown IV Tank is the upgraded version of the Crown III, constructed with Stainless Steel & Pyrex Glass and can hold a 6ml large capacity of E-Liquid (5ml in the normal tube). The biggest highlight of the Crown IV however, is its advanced patented Pro-FOCS, or Pro Flavor Core Optimization System. Pro-FOCS absorbs E-Liquid in the condensation holder through regular usage and vaporizing it.
The Dual SS904L coil and Double helix mesh coil available for the Crown IV achieves even heating to produce excellent flavor. The top filling design allows for easy refilling, and the bottom adjustable airflow system provides a smooth drag. 6 colors are available to choose from.
