The Uwell Crown IV is the latest version of the notorious Uwell Crown Tank! It has numerous upgrades from its predecessor, producing better-tasting flavor and even more vapor. The Crown IV’s most noticeable upgrade is its reimagined design, featuring a shiny gloss finish, bright crown logo, and sharp grooves. It also features a 6mL capacity bubble glass, adjustable airflow, triple airflow, and a wide bore drip tip. It utilizes plug and pull coils, which are securely fastened with O-rings instead of threads. These unique coils are constructed with innovative materials, including SS904L, FeCrAI, and organic cotton. The Uwell Crown IV Tank is all around a fantastic tank, which is hands down one of the best flavor sub-ohm tanks out there!
