The Crown 4 replacement coils come in a 4-pack, and feature UWELL’s patented self-cleaning technology which collects excess eLiquid in a condensation chamber near the bottom of the coil and vaporizes it. This allows for less frequent cleaning of your Crown 4 Tank. These coils also have UWELL’s patented Pro Flavor Core Optimization System (or Pro-FOCS). Pro-FOCS recycles the air through the coil two times during intake in order to saturate each puff with as much flavor as possible.
The dual helix design in these Crown 4 coils are modeled after luxury watches and made out of high quality stainless steel, providing improved taste, vapor, and coil longevity. UWELL’s wicking material is made up of 100% Organic Cotton Fiber. These attributes combined with the airflow and self-cleaning abilities of the Crown IV series of coils, affords them the ability to extend their lifespan over previous coils in the Crown family.
Caution: These coils are low resistance sub-ohms coils. Which can be dangerous if you are not using the correct equipment. You must be sure that your device and batteries can handle sub-ohm coils. Please use 20 amp or higher batteries.
