Uwell Crown 5 Tank is 29mm in diameter, made of stainless steel, and finely polished to give it a bright luster and smooth feel. This tank includes a durable Pyrex glass tube with a 5mL e-liquid capacity. The Crown 5 Tank hosts a simplified quarter-turn threaded top fill system for faster refills. Thanks to the additional silicone seal, the e-liquid can stay in the tank and will not be lost during the filling process.
Inside the Crown 5 Sub Ohm Tank is Uwell’s patented self-cleaning technology that turns condensation into vapor before it can even build up within your atomizer, thus further protecting you from leaking problems.
In addition, within the atomizers is the patented Pro Flavor Core Optimization System or Pro-FOCS for short. Pro-FOCS Flavor Testing Technology provides vapers with the ultimate vaping experience by properly controlling the heating temperature, strictly managing the material quality, and completely restoring the e-juice flavor.
