The Crown IV Tank by UWELL is the newest addition to the Crown family.  This tank features a simplified threaded top-fill system, 6ml MAX e-liquid capacity, and a striking visual design.  The simplified quarter-turn threaded top-fill system offers faster refills, so you have less downtime between vapes!  UWELL also designed their Crown IV coils with material improvements and a patented self-cleaning technology.  This new technology allows the coils to absorb excess e-liquid into a condensation chamber for later vaporization during usage.  This helps reduce wasted e-liquid and even lessens the need to clean the detachable structure of the tank.  Purchase your UWELL Crown IV tank today to enjoy its great flavor and ease of use!

Please note: This tank should NOT be used on any standard 3.7V battery. The resistance of this atomizer is too low for certain devices; meaning batteries with a standard voltage will think there is a short in the atomizer when really it is too low of a resistance for the battery to power. For any questions about what device would work best for you, please contact us directly!

Warning: You should NOT use sub ohm tanks on devices with hybrid top caps which are mainly found on mechanical devices. It is a top cap with no connection pin, meaning the atomizer makes direct contact with the battery. Using a sub ohm tank on a hybrid top cap could potentially result in catastrophic battery failure!
