Uwell Crown IV Tank

The Crown IV Tank by Uwell is one of the most advanced tanks in the Crown series, combining premium build quality with innovative performance features. Designed for sub-ohm vaping, it enhances flavour production, vapour density, and overall efficiency.

Built with durable stainless steel and reinforced Pyrex glass, the Crown IV offers a solid and stylish construction. The improved quarter-turn top-fill system allows for faster, cleaner refilling, while the patented self-cleaning technology reduces condensation build-up by absorbing excess e-liquid into a chamber that can be vaporised later. This minimizes leakage and reduces the need for frequent cleaning.

The tank also incorporates Uwell’s Pro-FOCS (Pro Flavour Core Optimisation System), which recycles airflow through the coil core twice to intensify flavour and deliver a smoother, more saturated vape. A protective drip tip cover is included to keep dust and debris out when not in use or during travel.
