Uwell Crown IV


Uwell’s Crown IV tank is the new flagship from Uwell, introducing a new line of Crown coils with improvements to their materials, a simple threaded top-fill system, 6ml maximum juice capacity, and an elegant design. The Crown IV boasts a brand new patented “self-cleaning” technology within the atomizer itself, absorbing excess eliquid into a condensation holder for later vaporization. This is done to help reduce wasted eliquid and lessens the need to clean the entire tank. If all that wasn’t enough, the atomizers contain a new technology known as the Pro Flavor Core Optimization System, or Pro-FOCS for short. The system recycles air twice through the core of the coil to saturate the recycled draw with additional flavor. Like other tanks seen this generation, the Crown IV features a quarter turn turn top-fill system with oversized fill holes.
