Uwell Crown IV 2ml Sub Ohm Vape Tank 510 Thread

Uwell Crown IV Sub Ohm Tank: Performance Built Around Flavour

The Crown IV from Uwell is a sub ohm tank that takes flavour production seriously. At the centre of it is Uwell's patented Pro-Flavour Optimisation Core System, known as Pro-FOCS, which recycles air through the core of the atomizer twice before it reaches your lips. The result is a draw that feels denser and more saturated than a standard single-pass airflow design, with each inhale carrying noticeably more of the e-liquid's character.

The Dual Helix Coil System works alongside Pro-FOCS to distribute heat evenly across the coil surface, which keeps the vapour consistent from the first puff to the last. There is no hot spot burn-off that can flatten a flavour mid-session. The tank is compatible with three coil options: the UN2 Mesh 0.23 Ohm for mesh-driven warmth and cloud, the Dual SS904L 0.2 Ohm for higher wattage output between 70W and 80W, and the Dual SS904L 0.4 Ohm for a slightly cooler, more flavour-focused vape at 60W to 70W. Each coil type produces a different character from the same tank, which makes the Crown IV a versatile platform for vapers who like to adjust their setup.

Filling is handled through a quarter-turn top fill design that opens cleanly and seals without fuss. The bottom adjustable airflow ring gives you control over draw resistance, from a looser, airier pull to something tighter and more direct. The hand-polished stainless steel construction and gold-plated 510 connection give the tank a premium feel that holds up to daily use. Uwell's patented self-cleaning technology helps the coil shed residue between fills, which extends coil life and keeps the flavour cleaner for longer. Pair it with a compatible mod from the accessories range or pick up replacement coils to keep your stock turning.

Uwell Crown IV Tank Specifications

The tank ships with one 0.4 ohm Dual SS904L coil (recommended 60W to 70W) and one 0.2 ohm Dual SS904L coil (recommended 70W to 80W), plus a pack of O-rings, a drip tip cover, and a user manual. The 2ml TPD glass is the only glass supplied. For customers who want a ready-to-use setup without a separate tank, the prefilled pods range is worth exploring alongside this listing.

Stocking the Uwell Crown IV at Trade Prices

Trade accounts at Vapes Wholesale UK give verified retailers access to wholesale pricing across the full hardware catalogue, and the Crown IV sits at a price point that works well as a retail upsell alongside coil replenishment sales. Free delivery on orders over £300 makes it practical to combine tank stock with coil packs and e-liquid in a single order without paying for carriage.

The five colour options, Sapphire Blue, Black, Metallic Green, Stainless Steel, and Purple, give you enough range to cover different customer preferences without needing to hold deep stock in a single finish. Retailers stocking the Crown IV alongside a selection from the e-liquid range tend to find it drives repeat coil and liquid purchases from the same customers.
