Uwell Project Sub Ohm Tank Review

With many brands on the market, Uwell is one that has perfected its craft. The vapor product giant has existed within the vaping industry for years, developing some of the most innovative products bearing the Uwell name. While it may not be the most known name in vaping when it comes to its devices, it has certainly built a reputable rap sheet when it comes to sub-ohm tanks. Out of its quite extensive collection of hits, the Uwell Crown series has gained the most popular amongst consumers, while receiving glowing reviews both online and off. What sets the tanks within the series apart from the rest is a culmination of three things, in particular, the quality, appearance, and performance, which is the basis of all tank options. The series exceeds all others in every category, and its latest to carry on this trend is the Uwell Crown 4 Sub-Ohm Tank, Project Sub-Ohm Edition.

Both Uwell and a division of VaporDNA have collaborated to create the Project Sub-Ohm (PSO) Edition of the Uwell Crown 4 Sub-Ohm Tank, which is a limited edition tank that shares the PSO logo. The division often slaps its logo on various products to signify that it has either collaborated with a manufacturer on a special edition product or have altered it in some way, such as providing special finish options. In a case of the Crown 4 Tank PSO Edition, the tank has endured a gorgeous re-color to any already brilliant design.

The Uwell Crown 4 Tank looks outstanding at every angle, boasting a shiny blue finish and shiny Delrin wide bore drip tip that presents the Project Sub-Ohm Edition logo. The tank not only looks fascinating, but it has been made with fascinating materials that enhance its durability. Constructed of a superior stainless steel material and utilizing a pyrex bubble glass, withstanding everyday conditions won’t be an issue. The tank itself shares a large 6ML e-liquid capacity, and to fill this massive area with liquid, there is a quarter turn threaded top fill system that makes refills even easier. At its base, there is a dual knurled adjustable bottom airflow control ring to fine-tune a balance between both flavor and vapor, but the insides are where the magic happens with the Uwell Crown 4 Tank. It adopts the Uwell Crown 4 Coil Line, which offers an array of performance-drive coil options, including the 0.4-ohm Dual SS904L Coil that’s rated for 60-70W, and the 0.2-ohm Dual SS904L Coil that’s rated for 70-80W. Its optional coils consist of the 0.25-ohm SS304 UN1 Coil and the 0.23-ohm FeCrAI UN2 Coil.

Additional features include a 5ML standard glass that comes included with the Crown 4 Tank, Uwell’s patented self-cleaning technology within coil head that has the capability of absorbing excess e-liquid, and the patented Pro Flavor Core Optimization System (Pro-FOCS) which allows the tank to recycle the in-taken air twice through the coil to saturate the draw and add even more flavor. It’s a very complex sub-ohm system that’s designed to satisfy in all facets.
