UWELL Crown 4 IV Sub-Ohm Tank

The Uwell Crown 4 IV Sub‑Ohm Tank is a dedicated vape tank designed for users who prefer the smooth, consistent vapor production of mesh coils. With a compact diameter of 28 mm, it offers an ergonomic grip that fits comfortably in hand while delivering a substantial 5 mL pod capacity. Its sub‑ohm construction allows for higher wattage operation, making it suitable for advanced vapers seeking dense clouds and robust flavor. The Crown 4 IV combines the versatility of a mesh coil with the power of a sub‑ohm tank to provide an engaging vaping experience.

Heating System – Mesh Coil Technology

The Crown 4 IV utilizes a mesh coil heating element that distributes heat evenly across its surface. This uniform heating reduces hotspots, ensuring consistent vapor quality throughout each puff. The mesh design also allows for a larger contact area with the e‑liquid, enhancing flavor extraction and reducing the likelihood of dry hits. Users benefit from smoother draws and longer coil life compared to traditional wire coils.

Sub‑Ohm Performance

As a sub‑ohm tank, the Crown 4 IV is engineered for higher wattage settings that produce denser vapor clouds. The low resistance of the mesh coil enables efficient power transfer from the battery, maximizing vapor output while maintaining flavor integrity. This design caters to vapers who prefer a more intense throat hit and larger cloud production without compromising on taste. The sub‑ohm configuration also supports extended vaping sessions due to its efficient use of e‑liquid.

Capacity – 5 mL Pod

The tank’s pod capacity is specified at 5 mL, providing a generous reservoir for flavored or nicotine‑free liquids. This volume allows users to vape longer between refills, reducing the frequency of maintenance. The larger capacity also contributes to a steadier vapor output as the liquid level remains relatively constant during use. Users can enjoy uninterrupted vaping sessions without frequent top‑ups.

Build – 28 mm Diameter Design

The Crown 4 IV features a 28 mm diameter that balances portability with a comfortable grip. The compact size makes it easy to carry in pockets or bags, while the shape ensures a secure hold during active vaping. This design also facilitates precise airflow control, allowing users to adjust draw resistance for their preferred style. The tank’s build supports both casual and advanced vapers seeking a reliable, handheld device.
