Shenzhen Uwell Technology is based in China; they pride themselves in going that extra mile when it comes to their products and customer service.

Uwell have had many well received kits and tanks in the past including the Iron Fist kit, the Hypercar kit, Nunchaku Starter Kit and Nunchaku RDA Kit as well as the Crown Series of Stock tanks and the Valyrian tank.

So what do we think of the Crown 4 Kit? Will it be the King of Vapes or will its Crown slip? Let take a detailed look……………….uwell crown 4 vready

This Kit was sent to us for the purpose of review. As always my thoughts and views are my own.

Tank

The Crown 4 Atomiser is made of SS, Pyrex and Delrin. The tank breaks down into 6 parts including the pre installed coil.uwell crown 4 bits tank The 25mm diameter Crown 4 tank is very well designed and the build quality is top notch, it features a host of improvements from the previous tanks in the Crown series, including a sturdier construction, a simplified ¼ turn cap, the top-fill port has 4 kidney shaped slots.uwell crown 4 FPThe tank has adjustable cylon bottom airflow with triple slots. uwell crown 4 tank base AFThe chimney section has a “Min” line for liquid level;uwell crown 4 liquid min Branding on the tank body is at a minimum with just a crown one side.uwell crown 4 chim adv The tank boasts an innovative, self-cleaning technology in which the coils are able to absorb excess e-liquid into a separate chamber, which can then be vaped later on!

Not only does this help to reduce e-liquid wastage, but it means that you don’t have to clean the tank as often as you would with other tanks.

The kit is supplied with 2 stock coils 0.4Ω (60-70w) and a 0.2Ω (70-80w). Both coils are SS904L standard round wire.uwell crown 4 coils 904LTwo glass tanks were supplied with my kit a 5ml and 6ml bubble glass.uwell crown 4 tank glass The tank is topped off with a black 510 delrin drip tip that has a metal ring to match the colour of the tank.uwell crown 4 mouth pieceAll the treads function well with no burrs; the O rings are all of good quality.

Basic Guide to First Time Use

It is possible to change the coil while the tank is half filled with e-liquid.

Crown 4 Tank

  • Choose which glass tank suits you best, the glass is held by 2 thick O rings which can make it difficult to remove the glass I recommend running this section under warm water to aid removal.
  • Pre wick the coil by dipping some liquid into the coil to start the cotton soakinguwell crown 4 wick coil

How Does The Uwell Crown 4 Kit Perform?

For this review I have installed the 0.2Ω coil and filled the bubble tank with 3mg 50/50 Raspberry & Apple by Vapouriz.uwell crown 4 kit review

It’s been a couple of years or so since I used any Uwell products, I am impressed by how the company has matured in this time, the quality and design of this kit is simply beautiful.uwell crown 4 together

Power Mode 50 to 80W

Starting at 50w with the airflow (AF) set to half the resulting vapour was quite thick with a very yummy flavour.

Upping the wattage to 65w with AF to ¾ open the vapour was very thick and the flavour was very good.

80w AF open fully! I found the result was a little on the hot side for me and my micro lungs LOL, however the vapour was again very thick, so much so I almost filled my small office with 2 toots, the flavour for me was a little muted.

I prefer to fire this combo at 60w and ½ AF.uwell crown 4 power mode

TC Mode

While I don’t normally fire my Mods in TC during my normal vape time the tests I ran with the SS904L supplied stock coils left me in no doubt that the Uwell Crown 4 mod fires extremely well.

I have been firing the unit with my normal 420f and 60w, maybe it’s my imagination but the flavour I get from these coils with those setting is exemplary, the amount of vapour produced was thick, nice and warm.uwell crown 4 tc mode

Tank Tests

I’m very satisfied with the Uwell Crown 4 tank which is unusual for me where sub ohm tanks are concerned.

Although I will say that in both modes chain vaping did leave the tank rather warm with some heat transfer to the mod, this is not unexpected as chain vaping is not the normal practice.

I have had no leaks from the tank not even purged vapour residue.uwell crown 4 together

Mod Tests

I have tested the mod with my Innokin iRoar Eurus RDA with a variety of different coils at different wattage’s up to 120w almost ruining my micro lungs LOL. The mod performs great at higher wattage even if it’s too much for me, while the ramp up is a tiny bit slow when compared to my Artery Hive 200.uwell crown 4 puff test

Niggles

The silicone strips or feet on the bottom of the mod, I personally feel they are to close together! If you knock the mod slightly while it’s standing it will fall over. While Uwell have mesh coils for purchase separately for the tank, they didn’t include one in the box, in the day and age of mesh coils this would have been nice to see.

Finally, some may the drip tip cover might be a good idea, for me personally it’s a wasted gimmick.uwell crown 4 MP cover

Pros

  • A very good looking kit
  • Build quality is very good for both tank and mod
  • Design is good for both tank and mod
  • Menu usability is simple
  • Very good vapour production
  • Good flavour production

Cons

  • No Mesh coils included

Final Review Verdict

Well I have to say I am impressed with the Crown 4 kit. Both together and as separate items. While they are well built and gorgeous to look at I wouldn’t call the kit the king of vapes but it does a prince of a job at trying.

I would say that the whole kit is aimed at the intermediate vaper.

I was a little confused with their choice of stock coils included with the kit because of the popularity of stock mesh coils these days I was expecting them to be included! The idea of the drip tip cover is a novel waste of time that I will never personally use.

Would I buy the Uwell Crown 4 kit should mine get damaged or lost? One word “Yes”.

Kevin Jeffrey
Hi my name is Kevin, I started vaping back in 2009 mainly because my little boy at 3 years old was starting to copy the way daddy smoked a cigarette! In these past years I have gained a fair amount of experience with different types of vaping hardware, I am not an expert by any means I'm just a normal guy who has made a hobby from vaping! Being disabled, vaping has given me a gateway to meeting people from all different walks of life, many of those I would not have met under other circumstances. The way I look at my reviews is, if I can convince just one person to give up the stinky’s my job is done. I class myself as a tinkerer as I like to take things apart to see how they work and put them back together, yes that includes e-cigarette mods! One day I would like to be able to design my own mod. I am a dedicated father, and husband to my sweetheart of nearly 30 years! Family to me comes before anything else.
