With advanced patented self-cleaning technology, the new Crown 4 tank can absorb the e-juice in the condensation holder through regular usage and vaporize it. The Crown 4 tank utilizes Dual SS904L coil and Double helix mesh coil to achieve heating evenly and produce excellent flavour. Coil options for the Crown 4 (not compatible with previous models) are:

•    Dual SS904L Coil 0.2ohm – 70-80W

  • Crown 4 5

    This tank has been a long time favourite of mine and so glad I came across this site that had them at a superb price and received 5 10ml eliquids totally free. Well worth it and a great company

  • Will be good... 4

    Build quality is excellent and coils are good. Very good flavour and decent clouds. Bought the bulb glass to increase the ridiculous 2ml capacity but can't use it yet as the tank is a different size to the non-TPD version. Uwell say a part will be available soon to enable TPD size tanks to use the bulb glass. Until then I've bought a Freemax Mesh Pro, which is even better!

  • Very nice 5

    I am not a experienced vaper but this is way better than the original tank of my isub cool fire IV plus. It comes with different coils which was nice for me to see how different vaping they provide. My favourite now is the dual 0.25 Ohm coil.

  • Original UWell Crown 5

    A great tank with a well deserved name for quality and reliability, a great vape with really good airflow, I would recommend this tank to anyone who enjoys full flavour and also likes some decent clouds.


    I rarely write reviews unless a product is outstanding and this tank is outstanding, Flavours that I thought were a bit meh using other tanks really come alive in this beauty. It's a thirsty beast though and you will get through some juice. The .25 coils also need some power to get the benefits from them, I'm running at 60-80W. Had some initial teething troubles on first use, some leaking through the air vents but that was down to my ineptness not the tank. You may also need to run half a tank of cheaper juice through it on first use to get rid of a what I assume is light oil residue from the manufacturing process but when this tank is in full flow I can't think I've used a better one. Buy one now you will not be dissappointed!!

  • best atomizer yet! 5

    Read PURE PLEASURE...THIRSTY PLEASURE review. He sais it all! And pay extra attention to the first paragraph about wicking the coil! Enjoy...!!


    I've been through a number of tanks, from MTL and DTL. Without a doubt this is the smoothest and most enjoyable tank I have used, the flavours and clouds are incredible. There is a good airflow range, the tank itself is very well built and I have not had a single problem with leakage. I advise priming the tank slowly; starting off with a low wattage and building up to your required level to prevent burning out the coil. I am still on the pre-installed 0.25 dual coil after a weeks use so yet to try the 0.5 coils. One major downside to this tank, IT DRINKS....ALOT!! I can't use it all the time because it would go through a 30ml bottle of liquid in a day easily. I leave this one for a morning and evening vape. I haven't tried a TVF4 so I can't compare the two, but without a doubt this is the best tank I've owned to date (used on an Innokin Coolfire IV TC100). Top marks to GSF for an excellent price and super rapid delivery!

  • Awesome tank! 5

    Along with the cleito, if I'm using a tank rather than an rda this is my go too! Great vape every time, the flavour is great, especially with the OMG Cinnamon Roll juice these guys do. My only frustration is that because of the width of the air flow control it won't fit on a eLeaf Pico due to the battery cap getting in the way, other than that is bang on, especially for the price you pay!

  • Not all that they claim it to be 3

    This is the fourth tank I buy based on product reviews, and it's the second product where the reviews are - at best - unjustified. I own a Smok TFV4 (full size), a TFV4 Micro, a Kanger Toptank Mini, an Aspire Triton Mini, and now the Uwell Crown. I do not detect any improvements in flavor compared to both the TFV4s, and it certainly *does not even match* the Toptank Mini, which as far as i'm concerned is THE go to tank for flavor. There is, however, a massive improvement compared to my Aspire Triton Mini, having said that, the triton mini is useless in the flavor department regardless of reviews to the contrary as you can only taste strong flavors in that one. all subtle ones taste like clear, unflavored liquids. The coils for the Uwell Crown are the most frustrating ones i've bought so far (1.2 ohm, i don't sub-ohm) within 2-4 hours of use you already see a decrease in the vapour production of 1/3 to half the initial capacity. They are rated at 10-30 watts, but that's wishful thinking: they produce a barely visible wisp of vapour at 10, and very little all the way up to 21 watts. they begin to become useful (yet still too little) at 22 watts with 24 the sweet spot. they begin to burn at 25.5 on long draws therefore restricting the effective range to 24-25.4 watts. finally, when used at that range, they last 2 days before they begin to burn every time, requiring you decrease the wattage (but note that, as explained before, those two days you'll be vaping at 2/3 to 1/2 their initial production). with some management, and sacrificing vapour production, you get 3 days out of the 1.,2 ohm. So, IMHO this is an **acceptable emergency tank** but nothing else. EMERGENCY, not a main, and not even a backup, as those two roles should be filled respectively by the Kanger Toptank Mini and one of the Smok TFV4 which are all good. All those excellent Crown reviews are day-1 impressions and dedicated to taste only, (which is admittedly not bad, but certainly not great) then carried along by the sheeply masses that wouldn't dare to offer a different opinion from famous reviewers. grow a pair and do your own thinking, you're spending YOUR cash, not theirs.

  • The Best Tank I Use 5

    The Uwell Crown tank is my favourite sub-ohm tank. I liked it so much I have bought three in total from Having three allows me to have several mods on the go with different coil and juice combinations. The Uwell Crown is a top filler and the design is such that it is very easy to fill. Disassembling for cleaning is simple. There is excellent air flow adjustment and the flavour I get with my current favourite tobacco juice (BCL Drummer in 6mg 70/30 vg/pg) is superb. The Uwell Crown coils are huge and contain a lot of cotton. If one disassembles the 0.5Ω coil for example, the coil is wrapped with seven pieces of cotton, each approximately 3cm x 1cm. That is a lot of cotton. Additionally, there is another piece of cotton of similar size between the inner and outer stainless steel coil housing. As the coils are wrapped in so much cotton one needs to prime these coils carefully to ensure optimum wicking and thus obtain the best flavour and cloud production. One should be patient in preparing these coils for vaping. Such patience will be rewarded with a truly superb flavour and great clouds. If one is not sure how to optimise the Uwell Crown coils then may I recommend this video on YouTube by Darrel Shurgin of Quest4Vape: In essence the Uwell Crown tank is well engineered, easy to fill, simple to disassemble, produces superb flavour and outstanding cloud production from the stock coils and is very reasonably priced. Additionally, I thoroughly recommend the Uwell Crown RBA - I may review this separately but if one wants incredible flavour and huge clouds then get the RBA too.
