One of the noteworthy Uwell products is Uwell Caliburn Pod system. It is unlikely that you will say “wow” when you see it for the first time – customers see such new products almost every day. The Uwell Caliburn form factor is the usual vape stick, the dimensions are probably average. But such a device can comfortably settle almost anywhere – whether it’s a pocket or a purse.

A replaceable cartridge has a standard for this segment capacity. It can be refilled from above – just remove the mouthpiece. The connector is magnetic. To control the fluid inside, there is a small slot in the body of the mod.

The main body is covered with aluminium and hides a fairly good built-in battery inside. Moreover, it will be charged, according to the manufacturer’s information, just instantly – about half an hour. The connector for these purposes is at the bottom of the device.On the front side of the device, we notice a neat, slightly protruding, fire button. Directly below it is the small dot of the LED indicator.

The tanks of this company are not very popular in comparison with other brands and it is very unfortunate. Uwell Crown took the title of the best tank of the year according to the portal vaping360.com. And now a new version came out – Uwell Crown 3, which can win the same title. If the first and second versions were only in 2 colours, then the 3rd pleases us at the start of sales with a whole palette – in addition to the classic black and steel options, matt black, rainbow and sapphire blue are available.

And also nine drip tips: red, green, gold, sapphire blue, lemon, dark green, orange, sky blue and purple.

Crown 3 comes in a small plastic box. On its reverse side is indicated the equipment, a brief description of the device, as well as certificates and warnings. Under the lid, we are met by a tank, spare glass and an evaporator.

Let’s disassemble the tank. Two o-rings hold a drip tip. It is made of Delrin, has a coloured metal insert. When we turn off the top cover – it has good knurling in the form of an engraving of the name and one turn of a wide thread, it holds perfectly.

Under the cover, there are two holes for filling the liquid. Turn off the base from the bottom. The evaporator here is not screwed into it, but is tightly inserted into the evaporation chamber, and is pressed by the base when screwed. The pin, though unregulated, sticks out enough.

While Daenerys in Westeros burns her enemies with a Dragonfire, the company Uwell released a real Valyrian sub-ohm tank. We can say that the Valyrian atomizer worthily continues the work of its predecessors, the Crown III and Crown III Mini.

A wide range of power, elegant design and getting into the theme of the famous series almost guaranteed him good sales even before the official release. A very reasonable price plays a significant role – about $ 30.

Instead of a box, the tank is packed in a real dragon egg. The atomizer came in five colour options, but the main one was the colour of Valyrian steel. Everything looks just fantastic, especially if you connect it with some suitable mod like Captain PD270. By the way, the appearance slightly resembles one of the versions of the Captain sub-ohm tank.

Another representative of the royal line – the maintenance-free tank Uwell Crown IV – impresses with its exterior. A solemn geometric pattern appeared on the case, the bubble glass gives solidity.

Even the dome looks like a crown painted on it. The fourth model in a row is smaller in height, but added to the waist: respectively 54.8 x 28 mm versus 62.7 x 24.5 mm.

Capacity with ordinary glass is 5 ml, the bubble version increases the volume to 6 ml. The lower part is massive, the upper has become even more moderate, which only added elegance.

The drip tip 510 sits well on the origins, is belted at the bottom with metal to match the main colour, and is made of Delrin. The top cap is removed in a quarter of a turn, freeing up wide filling holes. Tightening is controlled by rotating the steel ring on the base of the tank.
Key Features:

For this model, the manufacturer produces four interchangeable evaporators, two are found in the kit – 0.2 and 0.4 ohms with a vertical arrangement of spirals.

The head can be changed without draining the liquid, but its level in the inverted tank should be lower than the holes. The metal parts of the device are polished by hand.

Uwell Crown IV features a patented auto-cleaning and leakage protection system.
