 Uwell Crown 4 Tank Review

Uwell is an iconic name that is known throughout the vaping industry for its close attention to detail, the appeal, and performance that comes as a basis to each one of its products. The manufacturing brand has developed an assortment of vaping equipment that carries these traits, and that has landed it in a leading position. Recognized as an innovator within the industry, Uwell has developed many successful products, with the Crown Series being its most favored. From the original Crown tank up to the Crown 3, users across the globe have enjoyed the performance-driven sub-ohm tank and the many features that come along with it. The newly released Uwell Crown 4 Sub-Ohm Tank is just as impressive, receiving improvements all throughout and offering an even greater experience from a name you can trust.

The Uwell Crown 4 Tank features extraordinary quality and durability that will make the Crown 4 last for ages. It’s constructed of superior stainless steel material and uses pyrex glass material for added protection of its tank portion. The looks are quite satisfying, and it’s available in a variety of finish options, including Black, Blue, Green, Iridescent (Rainbow), Purple, and Stainless. The Uwell Crown 4 Tank sports a 28mm diameter, allowing for a 6ML e-liquid capacity with the use of its bubble glass. On the outside, you’ll notice a Delrin wide bore drip tip, a gold-plated 510 connection, and a dual knurled adjustable bottom airflow control ring that allows you to truly fine-tune the experience between both flavor and vapor production. At the top, there is a quarter turn threaded top-fill system, which makes refills a breeze.

The most favored part of the Uwell Crown 4 Sub-Ohm Tank has to be the use of the Uwell Crown 4 Coil Line, which consists of two coils that are included with the tank and two that are optional. The two that are included are the 0.2-ohm Dual SS904L Coil that’s rated for 70-80W and the 0.3-ohm Dual SS904L Coil that’s rated for 60-70W. The optional coils consist of the 0.25-ohm SS304 UN1 Coil that’s rated for 55-65W, and the 0.23-ohm FeCrAl UN2 Coil that’s rated for 60-70W. Each coil option utilizes organic cotton wicking for a consistent flow of e-liquid, and each will also offer an incredibly unique experience that is performance-driven.

In addition to its fascinating features and various coil options that definitely make an impact on performance, the Crown 4 Sub-Ohm Tank by Uwell also features Uwell’s patented self-cleaning technology, which is apart of the coil heads core design. It has the ability to absorb excess e-liquid, which will reduce the accumulated residual, along with its patented Pro Flavor Core Optimization System (Pro-FOCS) that gives the tank the capability of recycling the in-taken air once more through the coil, saturating the draw and adding even more flavor the second time around.

The Uwell Crown 4 Sub-Ohm Tank is an awesome addition to any device you to attach it to, and its many features and performance-driven coil options will present an extraordinary experience. It’s a very complex sub-ohm tank that we’re sure you’ll enjoy each time you use it.
