Valyrian 4 Tank by Uwell

Uwell Valyrian 4 (IV) Tank — Massive Capacity & Advanced V-Coils

The Uwell Valyrian 4 (IV) Tank is built for cloud chasers and flavor enthusiasts who want longer sessions between refills without sacrificing taste. With an industry-leading 8.5 mL e-liquid capacity and a wide 32 mm build, the Valyrian 4 lets you vape longer and refill less.

Designed for dependable, worry-free use, the Valyrian 4 features Uwell’s self-cleaning leak-proof technology and a protective silicone sleeve around the glass for improved durability. A press-to-open top-fill system and an upgraded PEI drip tip make refilling and daily use fast and mess-free.

The tank ships with Uwell’s new Advanced V-Coils (0.18 Ω and 0.35 Ω), optimized for high output and flavor — recommended at 90–100 W for the 0.18 Ω and 55–65 W for the 0.35 Ω — while remaining backward compatible with earlier Valyrian coil generations. These coils use upgraded wicking and PRO-FOCS flavor tech to deliver rich, consistent taste and long coil life.

Precise airflow adjustment and a large chamber provide excellent vapor production and tuning flexibility for DTL (direct-to-lung) sessions. The Valyrian 4’s robust stainless-steel construction and high-borosilicate glass (with silicone protector) combine to create a tank that’s both attractive and built to last.
