The Uwell Crown 4 Tank is the latest subohm tank from the Crown Tank series. Introducing a patented self-cleaning technology, the Crown 4 Tank atomizers can absorb the e-liquid in the condensation holder through regular usage and vaporizer it, reducing juice leakage and manual cleaning. The Uwell Crown 4 Tank is designed with a 6ml tank capacity with its pre-installed bulb glass, threaded 90 degree screw off top-fill system, and utilizes exclusive Uwell coils. The Uwell Crown 4 Coils utilizes Stainless Steel 904L (steel commonly used in luxury watches) with results in better flavor and longer lifespan. With Pro-FOCS Flavor Testing Technology, Uwell guarantees the perfect flavor profile for a satisfying vape.

I recommend this product

Crown proves worthy of the throne.

I have been using Uwell products since day one. Like every other manufacturer out there they have had their ups and downs. The Crown 4 doesn’t leak. It just doesn’t. That alone should rank it 5 stars. A dependable workhorse of a Sub-Ohm tank, it’s construction is like Tony Stark’s armor: impenetrable. The only drawback, it runs hot at higher temperatures and has yet to have full mesh coils as of this review. ( however don’t worry I have put some real coil killer juice high in sugar content and the coils have survived for quite a long time )

One of the best...

One of the best tanks out there. Coils last longer than most sub tanks out right now. Amazing flavor. Could have looser draw.

Ok

Good taste but Uwell should have put a mesh coil with the purchase of a new tank.you have to buy the mesh coils separately.coils don’t last as long as the crown 3 and I can swear I get better flavor from the crown 3 tank
