Uwell Crown 4 Tank


SKU: 13010005304

THE UWELL CROWN 4 TANK is constructed with hand-polished stainless steel and the classic 'Royal Crown' coil head chamber cap, this 4th version is extremely durable and gorgeous to boot.
With the installed bubble glass tube, this tank can hold a hefty 6ml of e-juice, but also includes a slimmer glass tube that can hold 5ml of e-liquid.
The biggest addition to this series of tanks is the UWELL Crown 4’s new patented self-cleaning technology. Each Crown 4 coil is designed with a condensation holder that will collect any un-vaporized e liquid during regular usage and feed it back up into the coil. This helps reduce the amount of wasted e-liquid, and reduces the need to clean the inside of your tank as often.
Moreover, these all-new coils also boast UWELL’s patented Pro Flavour Core Optimisation System (or Pro-FOCS). Pro-FOCS recycles the air through the core of the atomizer two times to saturate your draw with additional flavour.
The Crown IV Tank sports a simplified quarter-turn threaded top fill system for faster refills, along with an adjustable airflow slot at the bottom to provide smooth air intake. This Crown Tank’s striking visual design is augmented by hand-polished stainless steel which is notched at the top and bottom to make airflow manipulation and refilling your tank easier.
With stunning design elements, patented airflow technology, and the use of all new advanced dual helix coils, the Uwell Crown 4 Tank brings a royalty level of class to the world of Vaping!
