Uwell Crown 3 Tank is a simple, stylish device made of a stainless steel body and a quartz glass section. Quartz glass is more resistant to heat than pyrex glass, thus giving Crown 3 a competitive advantage. To protect the frame, the manufacturer adds a quality paint finish that can stand wear and tear over time.

If you need a minimalist tank with an easy to use structure, this brand suits you considering as it offers maximum wattage of 90W. Sophisticated tanks operate with up to 200W or higher even. However, even with the somewhat low watts, this product is powerful and performs highly in its category.

With the improved overall design, including the chimney, the device lowers leakage by reducing the amount of e-liquid condensate. Talking of structural improvements, Crown 3 has a removable coil base that collects condensation instead of it accumulating in the tank.

There are three adjustable air slots at the base to ensure sufficient cooling and prevent overheating. The openings have stoppers that provide steady adjustments instead of them spinning all the way; when you move one slot, the other two move as well for convenience.

Uwell Crown 3 comes with a lock key that keeps intact every part of the tank. If you need to disassemble the device for cleaning, remove the lock nut using the provided unlocking tool. You can also improvise and find another way to detach the nut. Even without the lock key, this tank still works. Removing it does not tamper with the vapor production.

On the other hand, the 5ml capacity allows you to vape several times before having to refill. Other products offer less volume. Crown 2 existed earlier before Crown 3, and it provides a capacity of 4ml, which is a slight difference.

The top-filling functionality makes it easy to replenish the reservoir. Unscrew the threaded top cap to see the two refill ports. However, the fill slots are small. Use a dropper bottle or a syringe to fill the tank.

Besides, the tank comes with a key to assist with changing the coils and disassembling for cleaning. Its wide-sized drip tip is available in several bright colors, including blue, black, purple, and matte black.

According to Uwell Crown website, you can select a tank color, but the company chooses which drip tip shade to go with it.

The 24.5-mm diameter sub-ohm tank has an updated coil system that balances flavor and vapor production. You can use either the pre-installed 0.25-ohm coil, or the 0.5-ohm wire, or both to take a parallel arrangement. The later offers a wattage range of 70-80W while the former provides 80-90w output.

Both coils boast of stainless steel material. Mounting and replacing the coil is as easy as plugging and pulling respectively. The coils lack threads so that all you need to do is pull them out and change them. Using the stainless steel 510 threading, Uwell Crown 3 is usable with most mods. The gold plated pin enhances efficiency.
