Uwell has built a strong reputation for high-performance sub-ohm tanks, and the Valyrian series continues to be a favorite among flavor chasers and cloud enthusiasts. In this comparison, we take a closer look at the Uwell Valyrian IV tank and the Valyrian III replacement tank to determine which one delivers better flavor, vapor production, and overall value. If you’re choosing between these two popular tanks, this guide will help you decide.
Overview
Both the Valyrian IV tank and Valyrian III are sub-ohm replacement tanks designed for direct-to-lung vaping. They focus on high-wattage performance, smooth airflow, and dense vapor output. While the Valyrian III remains a proven and reliable option, the Uwell Valyrian IV tank introduces an updated airflow design and improved coil performance for a more refined vaping experience.
Design & Build Quality
Overall Construction
The Valyrian III features a durable stainless steel construction with a classic sub-ohm tank profile. It feels solid and dependable, making it suitable for everyday use.
The Uwell Valyrian IV tank builds on this foundation with improved machining and a more refined finish. Premium materials and a slightly updated design give it a modern look while maintaining the rugged durability expected from the Valyrian lineup.
Tank Capacity & Filling System
Both tanks use a convenient top-fill system for quick refills. The Valyrian IV tank improves usability with a smoother top cap mechanism, helping reduce mess and making refilling easier during daily use.
Performance Comparison
Flavor Quality
Flavor performance is strong on both tanks. The Valyrian III delivers consistent and bold flavor, especially with high-VG e-liquids.
The Uwell Valyrian IV tank offers a noticeable improvement in flavor clarity. Enhanced airflow direction and an updated coil design improve saturation, resulting in cleaner, more detailed flavor at higher wattages.
Vapor Production
Both tanks are designed for cloud production. The Valyrian III produces thick, dense vapor that satisfies cloud-focused vapers.
The Valyrian IV tank matches this output while delivering smoother airflow, creating more consistent vapor with less turbulence during inhalation.
Airflow Control
Each tank features adjustable bottom airflow, allowing users to fine-tune their draw. The airflow on the Uwell Valyrian IV tank feels more refined, offering smoother adjustment and better balance between airflow and resistance.
Coil Technology & Compatibility
Valyrian III Coils
