Starting with the original Crown, Uwell opens a new chapter of sub ohm vaping. They have dedicated to offer a varying range of high-quality products from Nunchaku, Amulet and Crown 4. Today, I am going to review their newest member: Uwell Crown V Tank.

Product Introduction and Specification

The Uwell Crown V Tank is an upgraded version of its predecessor, the Uwell Crown 4 Tank. It features 5ml vape juice capacity with Patented Self-Cleaning Technology, which is helpful to prevent leakage and lessen the cleaning frequency.

It boasts a 29mm diameter offering bright luster and smooth feel. Uwell Crown V Tank utilizes quarter-turn threaded top fill system and adopts quarter-turn top cap design, which makes filling an easier task.

Build Quality and Design

I am impressed by the aesthetics of the Uwell Crown V Tank thanks to its exquisite manufacturing high quality. It is a pretty standard looking sub ohm tank with 29mm diameter. Uwell Crown V Tank comes with a 5mL bubble glass capacity and features a superior stainless steel tank construction, which has been delicately polished to deliver a smooth feel. It features a black drip tip with a red matching ring on the bottom. Outside of it is the roman numeral “V” embedded on the top cap and airflow ring. Uwell Crown V Tank is available in four pretty colours with shiny design. You can choose from black, silver, blue, red.

Features and Functions

Uwell Crown V Tank boats a patented self-cleaning technology, which is helping to reduce juice leakage and lessen the cleaning frequency. The atomizer can absorb the vape juice in the condensation holder through regular usage and vaporize it. Uwell Crown V Tank adopts an optimized cap design, which makes filling an easier task. You can simply refill your favourite vape juice by unscrewing the top cap 90°. The filler hole shaves a silicone check valve to prevent vape juice from leakage and provide a cleaner filling. Uwell Crown V Tank utilizes an exclusive Pro-FOCS flavour testing technology, which is design to offer the ultimate vaping experience by properly controlling the heating temperature, strictly managing the material quality, and completely restoring the vape juice flavour.

Coil Performance

The Uwell Crown V Tank is compatible with multiple mesh coils, which can fully atomizer the vape juice and deliver multiple vape experience. There are supposedly 3 coil options in total including 0.23ohm single mesh coil, 0.3ohm dual mesh coil and 0.2ohm triple mesh coil, but only 0.23ohm single mesh coil, 0.3ohm dual mesh coil included in the kit. Mesh coils are popular these days and better for sub ohm tanks.

I started with the 0.23ohm single mesh coil, which is best in the 65-70 watt range. It delivers decent flavour and smoothest airflow for DTL vaping. You will get fragrance and sweetness of the vape juice burst out with tasty flavour. Now we turn to 0.3ohm dual mesh coil. Flavour is really good when vaping for around 50- 55 wattage range. You can get a restricted DTL vape with warmer vapour and saturated flavour. The 0.2ohm triple mesh coil is recommended to vape for 65- 70 wattage. It is designed to provide slightly tight airflow for tight DTL vape, offering a fairly strong throat hit with huge flavour and decent flavour.
