6.6 tech score
In this article we review the Joyetech Delta II sub ohm tank.
So we have just reviewed the Kanger Subtanks as well as the Aspire Atlantis, and now everyone seems to be raving about the Delta 2 sub ohm clearomizer! There are so many sub ohm tanks that it is becoming increasingly confusing for anyone looking to purchase one. There is also the Eleaf Melo, Smok VCT and the Arctic sub ohm tanks to think about (reviews coming soon!). So many sub ohm tanks, and so much confusion! In this review I will try and shed some light on how we have found the Delta II and what separates it from the other tanks. I’ll try and compare it to the Kanger Subtanks and Atlantis where possible.

Stand out Features on the Joyetech Delta 2 Sub Ohm Tank
Juice Flow Control and Air Flow
So the Delta 2 has a very nice feature that the Subtanks and Atlantis don’t have – juice flow control. It might not sound like a big deal, but it is a really nice additional feature for a couple of reasons. Firstly if you like to use higher PG e-liquids, you can limit the juice flow slightly. This will prevent any over-wicking and potential leaking. When we used the Subtank on higher PG e-liquids it had a few over-wicking issues as the e-liquid is so thin. The Delta 2 doesn’t have this issue as you can set that juice flow to a smaller setting. It is also good for those who like to mouth inhale, as you can close the airflow and also close the juice flow to suit your draw.
The juice flow used fully open, worked flawlessly with heavier VG e-liquids, and the flavour was outstanding.
I really liked this feature and it is something that the other sub ohm tanks we have reviewed so far don’t have!
The airflow looks, on first sight, not to be as wide as the Subtank Mini or Atlantis. But actually as there are two holes (one on each side), it lets in a lot of air on the widest setting. The airflow on the Delta II coil itself seems to be a bit better than the Kanger Subtank and the Atlantis heads, and lets in a little more air.
Can be used at a Higher Wattage
So the Delta 2 works well at a much higher wattage than the Subtank. The sweet spot for me on the Kanger Subtank Mini is around the 25W mark, whereas the Delta works best at around 30W for me (some like it at 40W). The Delta II can be fired up to around 50W with no issues and I have even seen someone chain vape it at 60W without any dry hits at all.
I didn’t have any wicking issues at all with Delta 2. It wicks extremely well even with max VG blends. I have been using the Driptonic E-liquids on the Delta which are about 80% VG and it wicked with no issues whatsoever, without any dry hits.
Great Flavour and Clouds
Joyetech Delta II on the iStick 30W
So when it comes to flavour I have to say the Delta II is right up there with the Subtank. The flavour for me is best at around 30W and stays great all the way up to 50W. Some people argue that the flavour on the Delta 2 is better than the Subtank, but for me I think the Subtank is just a tiny bit more flavourful.
Clouds wise, again the Delta II is on par with the other sub tanks. My brother seemed to think it produced bigger clouds than the other sub ohm tanks we have tried thus far. I couldn’t really see much of a difference, but nonetheless the clouds are very impressive.
Cooler Vapor Production
One thing that I did pick up on, is that the vapor production is not as warm as with the Subtank. Even at the highest wattages the vapor is fairly cool on the Delta II, which really impressed me. Not everyone likes a warm vape, and the Delta II has a really nice vapor temperature. The drip tip is also very well insulated and it doesn’t get warm in the slightest, unlike the subtanks which tend to get a little on the warm side.
Solid Stainless Steel Casing
This is a positive and a negative in my opinion. The stainless steel casing looks awesome and will protect your tank very well, in case you decide to throw your Delta on the floor. I have dropped mine twice now and nothing has happened.
However it comes with the downside of not being able to see how much juice you have left. You can, if you look really hard, peek through the 6 tiny striped windows and see how much juice is left. I would loved to have some bigger windows to make this a little easier, as I like to see how much juice I am going through and how much I have left!
No Gurgling/Crackling Sound
I am surprised not many people have mentioned this, but this was a big positive for me. The Delta II is slightly quieter than the Subtank. It does have a slight whistle to it when you inhale, but it doesn’t have that loud, gurgling/crackling sound that I get from my Subtank mini. I am not sure if anyone else has noticed this on the subtank mini, but every now and then mine crackles and does so quite loudly. I never got this on the Delta 2!
Some Negatives and Things I Didn’t Like on the Delta II
Added Ceramic Wicking Material
So the wicking material I always thought was just organic cotton, but it turns out it uses both organic cotton and a high temperature woven wick, which is made out of some man made mineral fiber. I am not quite sure what to make of this material and its safety etc. It is meant to protect the cotton from dry hits and does a great job of that, but some people worry that the fibers break off easily and may be inhaled. Check out Pbsuardos article on it for more information on this. I am not too impressed about this woven wick material as it crumbles very easily and is in direct contact with the coil. The thought of inhaling that, freaks the shit out of me!
Thin Gap for Filling
The tank isn’t the easiest to fill if you don’t have a needle tip for your e-liquids. The gap between the chimney and the sides of the tank are pretty thin, so filling it with dripper e-liquid bottles is a bit of a pain in the ass. It isn’t a big deal at all and by no means a deal breaker, but just a little thing that annoyed me.
Steel Casing Restricts View of E-liquid
I mentioned above that the steel housing, restricts your ability to see how much e-liquid is left in the tank. This might not bother anyone, but as I said above, I would like to see some bigger windows so I can see how much e-liquid I am getting through and how much I have left.
No RBA Included
For some people, myself included, this won’t be an issue at all, as many won’t want to use the RBA. However I do think a lot of people will be disappointed that they will need to spend an extra $10 dollars on the RBA deck. I think it would save a lot of people money, if they included the RBA deck, as many might at some point want to give the RBA a go and play around with rebuilding the coils etc. My brother and I are both happy to use the 0.5ohm coils, so this isn’t an issue for us.
Recommend Using a 50W Device with the Delta 2
Some vapers might not have a device that goes above 30W and to be honest the Delta 2 works best for me at 30W. It works great on my Cloupor Mini and iStick 30W. However if you only use it up to 30W, you will always leave yourself wondering how it performs at higher wattages! If you want to play around with your Delta 2 at higher wattages, you will need something that fires up to 50W or 60W. We used the Vaporfi Vox 2 to try the Delta 2 up to 50W and it performed flawlessly all the way. I enjoyed trying out the different flavours at different wattages and for me the sweet-spot was around 30W which is great for me to use on my mini mods like the Cloupor Mini, MVP 3 and the iStick 30W. I do know that some people like to use it around 40W, so it will be personal preference, as to what suits you best.
Coils not as Available as Some of the Other Sub Ohm Tanks
I haven’t seen the Delta 2 being sold on as many online vape shops as the Subtank for instance. This is perhaps as it is still very new. I do get the feeling though that finding replacement coils will be a little more difficult with the Delta 2 than with the Atlantis or Subtanks. You can get all the sub ohm tanks from VaporDNA below, and save 10% on your purchase with our coupon code.
So there were many features that stood out for me on the Joyetech Delta 2. It really is on par, some might even say better, than the other sub ohm tanks performance wise. However that weird man-made woven wick material, really does put me off the Delta 2. I am no expert on materials at all, but it just puts me off. I don’t like the thought of small particles, potentially, going into my lungs. I am sure this won’t be the case and that Joyetech have tested it and everything, but still I’d rather be safe than sorry. If they bring out some 100% organic cotton coils, then I’ll use those, but until then, I won’t be using these coils again. It’s up to you to make your own assumptions about it, but I would rather stay on the safe side, in which case I will carry on vaping my Subtank Mini instead, which just uses Japanese organic cotton. If it is an issue for you I would recommend getting the Subtank instead or use the RBA deck on the Delta 2.
My recommendation is that if you want a sub ohm tank that can fire at a higher wattage (30-50W), and has juice flow control as well as cooler vapor, and if the wicking material isn’t an issue for you, then I would recommend getting the Delta 2.
If you want to vape at lower wattages (15-30) and want something that already includes the RBA, with a slightly bigger tank and in my opinion slightly better flavour, with pure 100% Japanese cotton wicking material (no man-made fibers), then I would opt for the Kanger Subtank Mini.
