Uwell Crown V 0.3Ω UN2-2 Dual Mesh Coil
The Uwell Crown V 0.3ohm UN2-2 Dual Mesh Coil is a premium replacement atomizer specifically designed for the Uwell Crown 5 (V) Sub-Ohm Tank. Optimized for 50–55W, this coil delivers a warmer, slightly restricted direct-to-lung (DTL) vaping experience with exceptional flavor and dense vapor production.
Performance & Design
Dual Mesh Structure
Features two mesh heating elements made of FeCrAl (Kanthal) that provide:
Even Heat Distribution: Dual mesh ensures consistent heating across the entire coil surface
Rapid Vaporization: Faster heat-up time for instant vapor production
Saturated Flavor: Enhanced flavor reproduction with every puff
Dense Clouds: Maximum vapor output for cloud chasers
Vaping Experience
Unlike the 0.23ohm single mesh (which offers a looser, smoother draw), the 0.3ohm variant is designed for:
Restricted DTL (RDTL): Slightly tighter draw than standard DTL
Warmer Vapor: Higher temperature for intense flavor
Optimal Wattage: 50–55W sweet spot
Balanced Performance: Perfect middle ground between flavor and clouds
Pro-FOCS Technology
Utilizes Uwell’s Pro-FOCS Flavor Testing Technology, which manages material quality for safety and purity, controls heating temperatures for optimal flavor, ensures authentic flavor reproduction, and prevents burnt taste and dry hits.
Installation
Features a convenient press-fit (plug-pull) design — quick, thread-less coil changes with no screwing or unscrewing required. Simply pull out old coil and push in new one. Secure fit prevents leaking.
Technical Specifications
Resistance: 0.3Ω (ohm)
Wattage Range: 50–55W (optimal)
Coil Type: UN2-2 Dual Mesh
Material: FeCrAl (Kanthal)
Vaping Style: Restricted DTL (RDTL)
Installation: Press-fit (plug-pull)
Technology: Pro-FOCS Flavor Testing
Compatibility
Compatible with: Uwell Crown V (Crown 5) Tank only
Not compatible with: Crown IV (Crown 4) — Crown III (Crown 3) — Other Crown series tanks
Note: The Crown V uses a unique press-fit design that is not interchangeable with older Crown series tanks.
E-Liquid Recommendation
These coils perform best with High VG e-liquids (70% VG or higher). Avoid 50/50 or high-PG liquids as they may cause leaking or gurgling.
Nicotine Strength
Due to the sub-ohm resistance and high wattage, 3mg or 6mg freebase nicotine is recommended. Nic salts or high nicotine (12mg+) are not recommended as high vapor production delivers more nicotine per puff.
How to Prime Your Coil
1. Put 3–5 drops of e-liquid directly onto the exposed cotton wicking ports.
2. Press the coil firmly into the tank base until it clicks.
3. Fill the tank with your high VG e-liquid.
4. Wait 5–10 minutes to let the coil fully saturate before vaping.
5. Begin at 40W and gradually increase to 50–55W.
6. Take 3–5 puffs without firing to draw e-liquid into the coil.
⚠️ Warning: Skipping the priming process will result in burnt cotton and a ruined coil!
0.3Ω vs 0.23Ω: Which Should You Choose?
0.3Ω UN2-2 Dual Mesh (this coil): 50–55W — Restricted DTL (RDTL) — Warmer vapor — Intense saturated flavor — Dense clouds — Better battery life — Best for flavor chasers and RDTL vapers
0.23Ω Single Mesh: 60–70W — Open DTL — Cooler vapor — Smooth balanced flavor — Massive clouds — Best for cloud chasers and open DTL vapers
Maintenance & Lifespan
Expected lifespan: 1–2 weeks average — 2–3 weeks for light vapers — 5–7 days for heavy vapers
Replace the coil when you notice: burnt or muted flavor — reduced vapor production — gurgling or leaking — dark caramelized cotton — harsh throat hit
Tips to extend coil life: Use high-quality, low-sweetener e-liquids — prime properly before first use — stay within 50–55W — keep tank at least 1/4 full — avoid chain vaping (wait 15–30 seconds between puffs)

Frequently Asked Questions
Will this coil fit my Crown 4 tank?
No. This coil is exclusively for the Crown V (Crown 5) tank and is not compatible with Crown IV or earlier models.
What wattage should I use?
The optimal range is 50–55W. Start at 50W and adjust to preference. Going above 60W may reduce coil lifespan.
Can I use 50/50 e-liquid?
Not recommended. This coil performs best with 70% VG or higher for optimal wicking and vapor production.
How do I know when to replace the coil?
Replace when you notice burnt taste, reduced vapor, or muted flavor — typically every 1–2 weeks depending on usage.
Do I need to prime this coil?
Yes. Always prime before first use to avoid dry hits and extend coil life.
