Uwell Crown 4 Tank


The UWELL Crown 4 is the ultimate vape tank, introducing a new line of Crown coils with big improvements, a simplified threaded top-fill system with 6mL maximum capacity, and an all new visual design.

The Uwell Crown IV features a patented self-cleaning technology within the core of the newly designed coils, which redirects excess e-liquid into a condensation holder for vaporization during later use. This helps reduce wasted juice and lessens the need to clean the detachable structure of the tank. In addition, within the atomizer is the patented Pro Flavour Core Optimization System, (or Pro-FOCS). This system recycles air (twice) through the core of the atomizer to saturate the recycled draw with additional flavour from the vaporized juice.
