The Uwell D1 vape tank is a leak-resistant tank designed with a unique dual chamber to reduce condensation and improve the quality of vapour. It's 4ml capacity allows for plenty of puffs before it will need refilling, and its top-fill mechanism ensures that the tank is as leak-resistant as possible.

The D1 features an innovative dual barrel design to separate the liquid chamber and provide a clear path for airflow, from the top of the tank to the D1 coils. Because of these two chamber design, the D1 is easy to use, fill, and vape on.

Important information about Sub Ohm vaping:

This device is designed for sub-ohm vaping. It requires more vaping experience to use safely, and extra care should be taken when using a sub ohm tank. Sub Ohm coils will only work on a mod capable of firing sub ohm atomisers, and Ni200 coils will only work on devices capable of Temperature Control. Please ensure that your batteries can handle the extra power requirements, and that your mod can handle the amps.

We also advise not to use any e-liquid with more than 6mg of nicotine, as your vapour may taste harsh. Sub ohm vaping produces a bigger throat hit than standard coils, and extra care should be taken.

You're gonna need a bigger boat... err... I mean tank (11 January 2017)

OK, so this is a good tank, with a couple of caveats

It produces really really lovely flavour from the start, even with fresh coils, with nice big clouds, and so far the claim of no leaks has held up true.

Cloud production seems to increase significantly after a day or two of use too.

It's built like a.. um... tank, all the screwy bits thread really nicely, the airflow ring is a pleasure to use, and it's easy to fill. I love the great big o-rings on the underside of the Uwell top caps.

The supplied drip tip fits like a glove and is pleasant to use - I think it's got a delrin inner part as it doesnt heat up too much.

And it's got a nice weighty feel so it feels like a quality bit of kit. It IS very heavy though compared to most other tanks - be warned!

So far then, so good!

However onto the down sides... it drinks juice like an unchecked 3 year old getting their hands on a carton of ribena for the very first time. Either that or the 4ml capacity is seriously overstated. I've been having to refill the tank 4 or 5 times a day, more at the weekends, whereas my previous Uwell Crown would last pretty much most of the day with a single top up in the evening. This is one expensive tank to run.

The other issue was mentioned in a previous review - due to the dual glass system, the outer glass fogs up making it difficult to see how much juice is left in the tank. Considering how quickly it uses juice up, this is not an insignificant issue.

I've just ordered a Uwell Crown SE1, and will relegate the D1 to being a spare or temporary tank. The only reason I've done so is due to the amount of juice it uses, and/or the capacity.

Maybe you'll get different results with a different setup to mine, so I'd say its still well worth considering, especially if you want something leak proof.

Great tank (10 January 2017)

I just bought this tank the other day and after 3 years of vaping and trying tons of different tanks I have to say this is by far the best for flavor and clouds that I have tried. There are a couple of downsides though, first being it is huuuge, it really is the biggest tank I have ever seen and looks massive on my mod. Secondly it is very fiddly to take apart there are a lot of pieces and tons of o rings etc so make sure you know where they all go when you take it apart for cleaning, if you miss one o ring there goes your leak proof feature. the other downside that I have found is the outer glass gets fogged up very quickly and you can hardly see your juice which is in the glass tank inside of the outer glass. All in all though I have to say that it has not leaked once and the flavor and clouds are extremely good, I just wish it was a bit smaller. Would I recommend this tank?? Absolutely 100% best Uwell tank out there by far and the coils are fantastic.

Uwell D1 (06 January 2017)

This is a good tank! Flavour is really good and the clouds are not bad. I still prefer the Crown 2 tank but that's my opinion. Thanks Vape Club for great service.

Favorite Tank! (22 December 2016)

I decided to give Uwell another chance after I had to give up the Crown II tank. Since they made such a huge success with the Crown I, I thought they might still have it in them.

And what a wonderful tank the D1 is! I use this on my Cuboid 150W, with a setting of 50W, and the juice taste from this tank and its coils is just amazing. Be prepared to spend some money on juice, though, because it is really hungry. But I guess that is the nature of a sub ohm tank chucking enormous clouds, providing a lot of flavor while doing so.

The icing on the cake is of course that it doesn't leak. Ever.

A fine piece of craftsmanship from Uwell, here.

Restored my faith in tanks (15 December 2016)

Some context for comparison:
I started with Innokin iSub tanks - not enough airflow for me, taste good, doesn't wick fast enough for me, so I get dry hits. (discovered that I am an impatient chain vaper)
I moved onto Cleito tank - (own three) plenty of airflow, taste OK, doesn't wick fast enough for me, so dry hits, got annoyed with having to open the top to get it to wick, got bored of that problem, high VG juices reduce the usable life of coil.
Then Cleito RTA - very good flavour, wicks fast enough (with jumbo glass), slightly inconsistent vapour, happy with it though, jumbo glass is delicate and have to be careful with it. Liked this because I could change the cotton and clean coil of gunky high VG juice. Nice.
Then Kanger Dripbox - good flavour but not very intense, wicks fast
Now Uwell D1 - OMG, like tasting juice for the first time, discovering new flavour notes, wicks fast enough for me, no leaking, consistent vapour, built like a tank. In summary: sod building coils and faffing with cotton, this thing is just great. I will get another one! It is a very big and heavy tank, but with flavour like this, I don't care. I'm sure the high VG juices will gunk up the coils, like on any tank, but I'm enjoying it too much to worry about that!

I'm not regreting it, but there are better ones out there (01 December 2016)

So my experience... It doesn't leak. Screwing the rings does not go smoothly, but one gets a hang of it. However, it seems to be 1ml capacity. I fill it up a million times a day. Overall, it's an ok tank. I can use it.

Quite Dissapointed (14 November 2016)

- Very fast service from vapeclub.
- Great flavour and cloud production
- Very little to no spit back when condensation cup is clean.

- It doesn't leak externally but internally it does. The condensation cup is filling up with liquid and I find myself having to have emptied it twice in mere two days. It's just wasted liquid.
- It's a big heavy tank
- The screw rings are finnicky and just not smooth.

Uwell D1 (12 November 2016)

Don't be put off by the Crown 2 fiasco, got my D1 today and am completely blown away by the flavour this thing chucks out, as well as some mighty fine clouds all with the 0.5 coil. So long as the coils don't go the same way as the crown 2 my Cleito will be put out to pasture. Superb prompt service from vapeclub as always.

Great tank (09 November 2016)

This is my first review I received the uwell d1 tank yesterday and I've got to say this tank is brilliant I have got the the crown 1 and crown 2 tanks and this tank Is by far the best yet The flavour I'm getting off these coils is amazing i'm really happy with this tank Great job by uwell I would highly recommend this tank

Great service from Vape Club yet again you guys do a great job

By from Northern Ireland

Good job Uwell (01 November 2016)

This is such an awesome tank. I bought a pack of Uwell .8 coils from VC as well. I'm not using the stock .2 or .5, but I'll probably give the .5 a shot.

I recommend buying this over the previous tanks Uwell have released. It's a no fuss, no hassle tank, and leakproof! I found very little to no juice on the condensation cup :) No prime wait as well.
