Uwell Crown 4 Sub Ohm Tank (w/ Self Cleaning Technology)

Touted by the industry as a leader when it comes to atomizer tanks, Uwell has made consumers very apparent of its capabilities. In just a short period of time, Uwell has managed to enter the market, manufacturer some of the most innovative vapor products, and situate itself as a leading brand. Out of its vast arsenal of products, the Uwell Crown series has become the most favored, and Uwell has a newly released to add to it, the Uwell Crown 4 Tank.

Quality Design, Performance and Materials

The Uwell Crown 4 Tank is predominately one of the greatest sub-ohm tanks to hit the market. It improves on the designs and performance of its predecessors, while maintaining the same incredible quality that’s visible throughout the entire collection of Crown tanks. Upholding a quality that consumers have become familiar with, the Uwell Crown 4 Tank is constructed of stainless steel materials and utilizes a bubble Pyrex glass tube to further reinforce its structure.

The top has a Delrin Wide Bore Drip Tip for enhanced airflow and smooth vapor delivery. Resting just below is its top cap, which can be turned 90 degrees to reveal its top filling design. The top fill design makes it even easier to refill the tank, allowing you to spend less time refilling and more time vaping. Its bubble pyrex glass tank gives way to a broad amount of room, allowing up to a 6ML e-liquid capacity for longer vaping durations. The bottom of the Uwell Crown 4 Tank hones in on airflow and its role in producing a solid performance. It consists of dual adjustable air slots that will give you the ability to fine-tune the balance for both flavor and the vapor production.

New Self-Cleaning Technology

The most impressive upgrade to the Crown 4 Tank is the new patented self-cleaning technology, which gives the Crown 4 coils the ability to absorb the e-liquid in the condensation holder through regular usage, and then it’s vaporized as normal. What this does is reduces potential e-liquid leakage and minimizes cleaning. To further strengthen its performance, the Uwell Crown 4 Tank utilizes the new Dual SS904L Coil and Double Helix Mesh Coil. These coils have been specifically designed for the Crown 4 Tank, and allows for more even heating, greater quality, and extraordinary flavor.

Combine its fascinating performance with the incredible quality and list of additional features, and you’ve got yourself another hit sub-ohm tank within the Uwell Crown series.

The Crown 4 tank is only tank l use. Coils are so easy to change it is almost effortless. I had alot of leaks with other tanks but none since l switched to the crown 4. Highly recommended

Genuine Uwell™ Crown 4 Sub Ohm Tank

Just got this tank today and so far so good. I didn't use the stock coils and instead replaced with those I ordered. Wow, talk about easy to replace and without spilling juice! Time will tell if Uwell's self cleaning system will prevent leaks. I'm not sure why the mesh coils still aren't available but I plan on getting some. I also use a Freemax Mesh Pro with triple mesh coils and though it blows the Crown 4 outta the water, as far as vapor production and possibly taste, the Crown does well. I'm sorta using it both as a MTL/DTL, and the Freemax for cloud chucking. Happy Vaping! :)

Love this tank. Best investment I have made in recent memory when it comes to vape products.

Genuine Uwell™ Crown 4 Sub Ohm Tank

I did really like the vapor production from this tank, however it leaks everywhere. Contacted Uwell who wanted pics of authenticity code, serial number and the invoice from VA. I then got to make a mess taking everything apart and replacing it, twice. Shipped it their California office for $11 (they advised USPS would have been a little cheaper). Received a brand new one two weeks later.. worked well for three days before the same leaking. Uwell asked if I replaced the glass. Done. Waste of $45 plus Cuttwood Juice.


We are very sorry to hear of this experience. Please note, we have a 60 day manufacturer defect warranty period. If anything goes wrong within that time, we will act as the intermediary and will deal with the manufacturer.

In the future, please contact us first. We would hate for you to go through all that unnecessarily.

Crown 4 is a perfect replacement for the Crown 3 which tended to leak. Since buying my Crown 4, I have not had a single leak. Nothing, nada. I have the anodized one which matches perfectly with my Sigelei Kaos Spectrum Box MOD. I get so many good comments from other vapers.
