Coil Technology and Compatibility

One of the most important features of the Uwell Valyrian IV Tank is its advanced coil system.

Included Coil Options

The tank typically includes two types of mesh coils:

0.18-ohm V-Coil

• Recommended wattage: 90–100 watts
• Produces very large vapor clouds
• Ideal for high-VG e-liquids

0.35-ohm V-Coil

• Recommended wattage: 55–65 watts
• Focuses more on flavor while still producing good vapor

These coils use a mesh structure combined with organic cotton, allowing faster heating and better e-liquid absorption. This results in smoother vapor and improved flavor output.

PRO-FOCS 4.0 Flavor Technology

The Valyrian IV Tank includes PRO-FOCS 4.0 technology, which is designed to recycle airflow and optimize vaporization. This system enhances flavor consistency while improving the overall efficiency of the coil.

Wide Coil Compatibility

Another advantage of the Valyrian IV Tank is its compatibility with Valyrian 2 and Valyrian 3 coils. This makes it easier for users to find replacement coils and experiment with different vaping styles.

E-Liquid Capacity and Filling System

One of the standout features of the Valyrian IV Tank is its large 8.5ml e-liquid capacity. Compared to many standard vape tanks that hold around 4–5ml, this larger capacity significantly reduces the need for constant refilling.

Advantages of the Large Capacity

The large tank size offers several benefits:

• Longer vaping sessions
• Less frequent refills
• More convenience for heavy vapers

Press-to-Open Top Fill Design

The tank uses a press-to-open top filling system that makes refilling quick and simple. Users can easily open the top cap, add their e-liquid, and close it securely.

This design also helps reduce spills and improves overall convenience.

Airflow System

Airflow control is essential for customizing the vaping experience. The Valyrian IV Tank features an adjustable bottom airflow system.

Users can rotate the airflow ring to adjust the amount of air entering the tank.

• Fully open airflow produces cooler vapor and larger clouds.
• Slightly restricted airflow creates warmer vapor and stronger flavor.

The airflow ring moves smoothly and allows precise adjustments, giving users more control over their vaping style.

Performance and Vaping Experience

When it comes to performance, the Uwell Valyrian IV Tank delivers impressive results.

Flavor Quality

Thanks to the mesh V-Coils and advanced airflow design, the tank produces rich and consistent flavor. Many users report that the flavor remains strong even during long vaping sessions.

Vapor Production

The tank is capable of producing large and dense vapor clouds, especially when using the 0.18-ohm coil at higher wattages. This makes it a great choice for cloud-chasing enthusiasts.

Smooth Airflow

The adjustable airflow system provides a smooth draw that feels comfortable and natural. Whether users prefer a more open or slightly restricted airflow, the tank performs reliably.

Leak Resistance and Maintenance

Another useful feature of the Valyrian IV Tank is its leak-resistant design.

The tank incorporates a self-cleaning condensation system that helps redirect excess moisture back into the chamber. This reduces leakage and keeps the tank cleaner during regular use.

Maintenance Tips

To maintain the best performance, users should follow a few simple maintenance practices:

• Replace coils when flavor begins to fade
• Clean the tank regularly
• Use e-liquids within the recommended viscosity range
• Avoid overfilling the tank

Proper maintenance will help extend the life of the coils and keep the tank functioning smoothly.
