Uwell VALYRIAN IV Tank Review
The Uwell Valyrian IV Tank is an 8.5ml sub-ohm tank, the largest in Uwell’s Valyrian family. It runs Uwell’s V-Coils: the 0.18Ω for dense direct-to-lung (DTL) clouds at 90–100W and the 0.35Ω for flavor at 55–65W. A press-to-open top cap makes refills one-handed, and a silicone sleeve protects the glass. See more from Uwell or compare other sub-ohm tanks.
Valyrian IV Tank Highlights
8.5ml Capacity
The Uwell Valyrian IV Tank holds 8.5ml, the most of any Valyrian tank, so you refill less often.
Press-to-Open Top Fill
Press the top cap with one hand and it opens for a refill.
Silicone Glass Protector
A silicone sleeve fits around the glass to cushion it against bumps and drops.
V-Coils and More
Two V-Coils come in the box, and Uwell says Valyrian III and II coils fit too.

V-Coil Ratings
Uwell recommends these wattages for the coils that come with the Valyrian IV Tank:
| V-Coil | Uwell rating | Made for | In the box |
|---|---|---|---|
| 0.18Ω mesh | 90–100W | dense DTL clouds | fitted |
| 0.35Ω mesh | 55–65W | flavor | spare |
We sell Uwell V-Coils in packs of 2. The Valyrian IV Tank also takes our Valyrian 3 coils.
How to Set Up the Valyrian IV Tank
- Prime the coil: drip a few drops of e-liquid onto the cotton in the coil’s wick holes.
- Fill it: press the top cap to open it, fill the tank, then close the cap.
- Let it soak: wait about 5 minutes so the cotton soaks through.
- Set the power: start at the low end of your coil’s range, 90W for the 0.18Ω or 55W for the 0.35Ω.
- Tune the airflow: turn the airflow ring at the base to open or tighten the draw.
Who the Valyrian IV Tank Is For
The Uwell Valyrian IV Tank suits DTL vapers who want a big 8.5ml tank and the choice of a cloud coil or a flavor coil. Pair it with a 510 mod that reaches 100W for the 0.18Ω coil. For a smaller 6ml Valyrian, see the Uwell Valyrian 3 Tank.
Good to know: Uwell says the Valyrian IV’s self-cleaning design redirects condensation, which cuts down on leaks and on how often you need to clean the tank.
