Uwell Crown IV Atomizer Vape Tank Fill 2ml E Cig UN2 Coil Glass Tube
Sub-Ohm Royalty: Uwell Crown IV Experience
A Legacy of Flavour Excellence
The Uwell Crown IV Atomizer Vape Tank continues the legacy of one of the most respected names in sub-ohm vaping. Uwell's Crown series has long been the benchmark for flavour clarity, and the Crown IV takes that reputation to new heights. From the very first puff, you are greeted with a dense, richly saturated vapour that captures every note of your e-liquid with stunning precision. This is a tank for vapers who refuse to compromise on taste.
Designed for Direct-to-Lung Power
The Crown IV is engineered exclusively for direct-to-lung vaping. The wide-bore drip tip, massive airflow channels, and high-performance UN2 coils work in harmony to deliver a smooth, airy inhale followed by voluminous cloud production. Whether you enjoy sweet desserts, sharp fruits, or cool menthols, this compact 2ml tank amplifies the intensity without introducing any metallic or burnt notes.
A Premium Aesthetic
Uwell is known for exceptional build quality, and the Crown IV Atomizer Vape Tank is no exception. The stainless steel chassis features elegant geometric engravings that resist fingerprints. The Pyrex glass tube is protected by a sturdy cage, offering durability without sacrificing the ability to monitor your e-liquid levels. It looks stunning on any mod.
Self-Cleaning Technology
The standout feature of the Uwell Crown IV Atomizer Vape Tank is its innovative self-cleaning mechanism. A unique rotating bottom airflow ring allows you to close the airflow and twist it to force any condensation or excess e-liquid out of the base. This eliminates the dreaded ring of moisture that collects under tanks, keeping your mod clean and dry. No more sticky pockets or dirty 510 connections.
UN2 Mesh Coil Optimisation
The Crown IV is designed around the revolutionary UN2 mesh coils. The UN2 0.23ohm Single Mesh Coil provides a massive heating surface area, resulting in exceptional flavour clarity and rapid ramp-up time. It operates best between 60-70W. The UN2 0.3ohm Dual Mesh Coil uses two mesh strips for even more vapour production, running best between 65-75W. Both coils utilise organic cotton wicking and are designed for high-VG e-liquids (70% VG and above).
TPD Compliant 2ml Capacity
This version of the Uwell Crown IV Atomizer Vape Tank features a 2ml e-liquid capacity, fully compliant with UK TPD regulations. While the capacity is reduced from the standard version, the top-fill design makes refilling incredibly fast and mess-free. Simply unscrew the top cap, fill through the large kidney-shaped ports, and replace the cap. You can refill in seconds.
Precision Adjustable Airflow
The Crown IV features a helical bottom airflow system. The control ring rotates smoothly, offering a wide range of adjustment. Fully open, the tank provides an airy, unrestricted direct-lung inhale perfect for massive clouds. Partially closed, the airflow tightens, increasing flavour concentration and providing a slightly warmer vape. The mechanism stays firmly in place once set, preventing accidental adjustments.
Threaded Top-Fill & Reliable Seals
Uwell has engineered the Crown IV to be completely leak-resistant. The threaded top-fill cap creates a perfect vacuum seal when closed, preventing pressure changes from forcing liquid out of the airflow. The coil seating uses high-grade silicone O-rings. When assembled correctly, this tank will not leak, even when carried in a pocket or bag.
The Perfect Upgrade
If you are using a starter kit tank and want to step into high-performance sub-ohm vaping, the Uwell Crown IV Atomizer Vape Tank is a perfect upgrade. It pairs beautifully with dual-battery mods, allowing you to push high wattages for extended periods. It is a convenient option for flavour chasers who still want reliable, daily performance without constant fiddling.
Simple Maintenance, Long Life
Keeping your Crown IV clean is effortless. The tank disassembles completely for washing. The glass is replaceable, and the spare parts bag includes extra O-rings. UN2 coils are widely available across the UK, ensuring you never struggle to find replacements. A single UN2 mesh coil can last one to three weeks depending on your e-liquid choice and wattage.
A Smart Investment in Quality
The Uwell Crown IV Atomizer Vape Tank is built to last. The stainless steel construction resists drops and wear. Once you own the tank, you only need to buy replacement coils and glass tubes, making it a cost-effective long-term setup. For the discerning UK vaper who demands the very best in sub-ohm flavour, innovative self-cleaning technology, and rock-solid reliability, the Uwell Crown IV is the undisputed king.
