Uwell returns in 2018 with the Crown 4, an evolutionary update to one of the most beloved Sub-Ohm Tank platforms in the history of our industry presenting a 6ml max capacity along with the new and improved Crown IV Parallel Coil Design. The Crown 4 features a 90 degree threaded top fill method that unscrews to reveal dual fill ports. The Crown 4 utilizes the new and improved Crown 4 Plug and Pull replacement coil style, with a thread-less design that features reinforced seals to provide a liquid tight fit and finish. The Crown 4 Replacement Coils consist of unique materials such as the SS904L and the FeCrAl (Iron, Chromium, Aluminum) coils, all of which contain organic cotton. The adjustable bottom airflow makes for smooth and effective airflow, and can be fully closed to seal the system effectively.
