Uwell Crown 4 Sub-Ohm Tank Overview

Uwell is back with the beautifully hand polished Uwell 4 Sub-Ohm Tank equipped with patented self-cleaning technology. The sleek superior Stainless Steel construction of the Crown 4 stands at 54.8mm with a base diameter of 25.7mm. This tank includes a durable Pyrex glass tube with a 5mL e-liquid capacity and a 6mL e-liquid capacity bubble glass tube that extends the diameter out to 28mm. These components come together to make an overall lightweight of 55g that, with the devices 510 threaded connector, goes great with any compatible box mod. At the top of the Crown 4 Tank is a wide-bore 510 Delrin drip tip attached by double o-rings for easy replacement with your favorite personalized 510 drip tip. To protect your atomizer from dust and debris, Uwell has included a Silicone drip tip cover that easily slides on and off your mouthpiece. Below the drip tip is a twist off top cap that only needs to be turned 90 degrees in order to be removed for convenient top filling. Giving the top cap a quarter turn, you will expose four large fill ports that allow access into your installed glass reservoir. Underneath the top cap is a Silicone ring that helps protect your tank against potential leakage. Inside the Crown 4 Sub-Ohm Tank is Uwell’s patented self-cleaning technology that turns condensation into vapor before it can even build up within your atomizer, thus further protecting you from leaking problems. Pre-installed inside the tank is an SS904L 0.4 ohm Dual Coil rated for use between 60-70W. Uwell has also included their SS904L 0.2 ohm Dual Coil rated for slightly higher wattages of 70-80W. Although these coils do not have the latest mesh technology, they utilize long-lasting, high quality Stainless Steel that is commonly used for luxury wristwatches. They also utilize a convenient threadless plug and play design for quick and easy coil replacement. Uwell has crafted two other unique coils for the Crown 4, which consist of the SS304 UN1 and FeCrAl UN2 Coil Heads. The SS304 UN1 has a double helix 0.25 ohm meshed coil rated for use between 55-65W. The FeCrAl UN2 consists of an Iron, Chromium, and Aluminum 0.23 ohm coil rated for use at 60-70W. Along the base of the Crown 4 Sub-Ohm Tank is an adjustable airflow ring with triple bottom airflow slots that can be fully closed for a more restricted vape. These airflow holes are equipped with stopping points to make it easier to remove the base and replace your coils. For this tank, Uwell used Pro-FOCS flavor-testing technology to ensure a satisfying draw with a balance of optimal flavor and massive cloud production. Available in a variety of striking colors, the Uwell Crown 4 Sub-Ohm Tank will be your favorite Uwell atomizer since the release of the original Uwell Crown One.
