Availability:: Usually Ships in 24 to 48 Hours Choose Your Color color*: Blue Purple Rainbow The UWELL Crown 4 IV is the ultimate flagship vape tank structure, introducing a new line of Crown coils with materials improvements, a simplified threaded top-fill system with 6mL maximum capacity, and a striking visual design. The Uwell Crown 4 presents a brand new patented self-cleaning technology within the atomizer core of the new Crown line of coils, absorbing excess e-juice into a condensation holder for later vaporization during usage. This helps reduce on wasted e-juice and lessens the need to clean the detachable structure of the tank. In addition, within the atomizers is the patented Pro Flavor Core Optimization System, or Pro-FOCS for short. This system recycles the in-taken air twice through the core of the atomizer to saturate the recycled draw with additional flavor from the vaporized e-juice. Also, the Crown IV Tank hosts a simplified quarter-turn threaded top fill system for faster refills and less downtime between cloud chucking sessions. Furthermore, the Crown 4 has a visually striking design, being hand-polished and knurled at the top and bottom ends, making airflow manipulation and unscrewing of the top fill system even easier.Quick Links: UWELL Crown 4 Replacement Coils Please see below for content information.Uwell Crown 4 Sub-Ohm 28mm Tank Features:28mm Diameter5mL Standard Glass6mL Bubble Glass TankSuperior Stainless Steel ConstructionPyrex Glass ReinforcementQuarter Turn Threaded Top Refill SystemUwell Crown 4 Coil Line0.2ohm Dual SS904L Coil - rated for 70-80W0.4ohm Dual SS904L Coil - rated for 60-70W0.25ohm SS304 UN1 Coil - rated for 55-65W0.23ohm FeCrAl UN2 Coil - rated for 60-70WDual SS904L Coil - Corrosion-ResistanceDouble Helix Mesh CoilSelf Cleaning TechnologyPro-Flavor Optimization Core SystemDual Knurled Adjustable Bottom Airflow Control RingGold-Plated 510 Connection Detachable StructureAvailable in Black, Blue, Green, Rainbow, Purple, Stainless SteelIncludes:1 Uwell Crown IV (4) Tank1 Spare Glass Tube1 0.4ohm Dual SS904L Coil - rated for 60-70W1.0.2ohm Dual SS904L Coil - rated for 70-80W1 Pack of O-Rings1 User's Manual1 Drip Tip Cover Accessories for this product...
