Uwell Crown 4 Coils 4 Pack - 0.23 Mesh

Restore the majestic performance, rapid ramp-up speed, and rich flavour fidelity of your sub-ohm setup with the authentic Uwell Crown 4 Replacement Coils in the premium 0.23ohm UN2 Mesh configuration. Precision-engineered by Uwell exclusively to power the iconic Crown 4 (IV) Sub-Ohm Tank, these coils abandon older wire constraints in favour of advanced honeycombed mesh geometry. Packaged in authentic boxes of 4 blister-sealed units, they offer the perfect crown-jewel upgrade for mid-to-high wattage vaping. 

The primary engine behind this coil's incredible performance is its chemically etched FeCrAl (Iron-Chromium-Aluminium) UN2 Mesh ribbon. Instead of traditional wire helixes that heat up slowly and unevenly, the UN2 mesh structure forms an open, uniform honeycombed matrix wrapped seamlessly along the interior wall. 

The defining factor of Uwell's global supremacy in flavour production is their proprietary Pro-FOCS (Flavour Optimization Core System). This advanced architectural layout carefully directs the internal airflow paths while strictly managing core operating temperatures. By vaporizing your e-liquid completely symmetrically across the 100% organic cotton fibre wick, Pro-FOCS strips complex flavour elements cleanly away from the element face. This means hidden fruit, dessert, or menthol notes are brought straight to the foreground without any flavour mutation or degradation.

The Crown 4 coil chassis features a smart, internal self-cleaning mechanism built directly into its base. In a standard sub-ohm tank, un-vaporized e-liquid condensation or weeping drops down through the airflow slots, causing messy leaks. Uwell isolates this by incorporating a dedicated condensation-holding well at the lower floor. During use, high-velocity incoming air loops through this holder, siphoning pooled condensation back upward onto the wicking core to be fully vaporized. This continuous recycling process keeps your kit bone-dry and extends the average coil lifespan. 

Because these high-velocity sub-ohm cores feature wide vertical chambers and massive outer wicking ports, they require thick, premium juices to safely maintain proper internal air pressure. They are optimized strictly for high-VG fluids, executing at their absolute best when paired with 70% VG or higher e-liquids and shortfills. Lower viscosity liquids—like 50/50 e-liquids or thin nicotine salts—should be avoided entirely to prevent flooding the wide-open wicking channels. 

⚠️ COIL PRIMING NOTICE: Because vertical sub-ohm mesh structures deploy a large column of compressed organic cotton, thorough priming is mandatory to avoid instant scorching. Drip 4–5 drops of e-liquid directly into the top center bore of the coil before screwing it into the tank base. Once the reservoir is fully reassembled and filled with juice, let the entire system sit undisturbed for 10 to 15 minutes to ensure total saturation before firing your mod. [1]
