CoilART Azeroth RTA Review

If dual coils just don’t do it for you anymore, check out the triple-coil Azeroth RTA from CoilART


CoilART Azeroth RTA Intro

CoilART has just released a couple of triple-coil-capable rebuildable atomizers, and I received both to review: the Azeroth RDA and Azeroth RTA.

After reviewing the RDA first, next is the Azeroth RTA. In addition to sharing the name, both use the same patented triple-coil deck, which I found to work quite well when reviewing the RDA.

Besides the obvious difference—one is an RDA and the other an RTA—there is another welcome difference between the two: the RTA includes a second velocity-style deck for dual-coil builds.

Beyond that, the Azeroth is pretty much like any other top-fill, bottom-airflow RTA. My concerns, as with any RTA, are how finicky the Azeroth is to wicking technique and whether it leaks. The RDA was fairly easy to build and a lot of fun to use, but this may prove a bit more challenging (for me) in comparison.

The Azeroth RTA is currently available directly from CoilART in black and stainless steel for the retail price of 44 bucks, and at Gearbest for $31.12 (SS) or $32.19 (black).

Notable Remarks

Inside the box

When I opened the box, the first thing I noticed (after removing the T-tool) was the extra velocity-style deck. I expected the RTA would be like the RDA, with a single triple-coil deck. The triple coil deck on the RDA was designed to work with dual coils, though it is not optimal—so it’s nice that the RTA includes a dedicated dual coil deck.

Moving on to the tank, it’s well machined, with minimal branding. The matte finish on my black review sample is smooth and even. When I unscrew the deck and SS top cap, both come off without a hint of grittiness or binding.

The Azeroth is a top fill RTA, and holds 4.5 mL of e-liquid, and not EU compliant.

There are all the expected spares, and more, including four replacement screws for each deck, full set of o-rings, spare glass, tool, instruction card, and CoilART vape band. There is also a second delrin top cap that has a short tip, that will accept 510 drip tips.

The decks

I already mentioned the dual coil deck. I intend to try it, probably with some clapton coils, but as with the Azeroth RDA, the main attraction is the triple deck.

The triple deck is the same as the RDA but smaller—it must fit under the chimney. Like the RDA, the deck has six short posts with holes in the top and screws on the sides. The wire holes are tiny. I intend to use single wire coils to help keep the heat down to a reasonable level, and prevent dry hits.

To change the deck, you just remove the base of the tank and unscrew the deck.

Side note: I have bitched about the screws on every CoilART RDA I have reviewed this past month due to the tiny Philips-head screws, and was happy to see hex grub screws on the triple-coil deck. Fantastic. However, they are still using the Phillips-head screws on the dual-coil deck. Grrrr..

Final note: neither deck allows juice flow control.


Nothing we haven’t seen before. Three adjustable bottom airflow slots on the deck direct airflow directly under each coil. Wide open, the airflow allows an unrestricted direct-lung inhale.

Me and RTAs

I’ll admit that I prefer to use an RDA, RDTA, sub-ohm tank, or squonker when I vape. Pretty much anything other than an RTA. Why, you ask?

Because any dummy can successfully build and use any of those, and you can count me among said dummies. On the other hand, the performance of an RTA like Azeroth can be quite sensitive to the wicking technique. Whether speaking about flavor, vapor, and especially leaks, RTAs often do not leave a lot of room for error.

I recently built an Ammit Dual Coil RTA for a review, vaped it for a very short time, and nothing seemed amiss. I went to bed and returned to my workspace the next day to find that the Ammit had puked the entire contents of the (full) tank all over my $150 regulated mod. I’ll admit: it was my fault, but still.

With my preferred gear, I never have to worry about that problem. So, wanna guess what happened with the Azeroth? I’ll get to that shortly.

Performance of the Azeroth

I built the deck with three single-wire 26-gauge kanthal coils. As with the RDA, I test-fit one coil in the deck and carefully trimmed the legs until the coil sat just a bit above the posts. In this case 4-4.5 mm is about right. Remember, if the coils touch the chimney you have a direct short, so I wanted to keep the coils as low as possible.

I installed the the three coils and wicked with organic cotton. When I wicked the coils, I made sure the tails just entered the juice wells. I didn’t pack the cotton in there, or leave any open space to allow the juice to flow directly into the deck.

After wicking, I painted the coils, assembled the tank and checked on my ohm meter – the resistance was 0.32Ω (no short), so I filled the tank.

This is the part of the review that I don’t like: trying to quantify vapor density and flavor and describe it in text. I ended up vaping for a short while at 35 W, which was fine for the three single-wire coils, and got very good vapor and flavor. (See?) The vapor was dense with a hint of warmth, and I didn’t get any dry hits or spitting. I like this build – even with three coils it won’t tax my single-battery mod at 35W, and I expect to get decent battery life. It’s a win for me…I thought.

I sat the mod down and walked away for a couple hours. Upon returning, I saw that the Azeroth had unloaded juice all over my mod. Damn it.

Problem? The tank was not tight. The deck was, but the top ring under the cap was more than a half turn loose. I tightened it, refilled, and put the tank on an atty stand overnight. Happily, I had no leaks and vaped another full tank without any problem.

The last thing I did was swap the triple-coil deck with the velocity-style deck. I’m happy for two reasons: I can swap the decks without emptying the tank, and I don’t have to disturb my triple-coil build. Sweet.

With a dual coil clapton build at 0.4Ω, wicked with organic cotton, the Azeroth performed perfectly. I did my job this time and had no spitting or dry hits, and most importantly… NO LEAKS!


  • Triple-coil goodness
  • Performs well in both dual and triple coil
  • 4.5 mL capacity
  • Dedicated dual-coil deck
  • Nice fit and finish
  • Good threads


  • Tiny phillips-head screws (on dual-coil deck)
  • Triple coil deck a bit fiddly to build (compared to velocity-style)
  • Not EU compliant

Look ma, no leaks...

At the start, I’ll admit that I had mixed feelings about the Azeroth RTA. I asked myself:

With my track record of struggling with wicking and leaks, do I really need three coils/wicks to compound the issue?

Not really…but the Azeroth RTA has convinced that it’s no big deal.

As with the RDA, it is the triple-coil deck that sets the Azeroth apart from the rest. Once I got past the admittedly self-inflicted problems the Azeroth RTA performed perfectly, and I will very likely continue to use three coils. Of course, I’m always happy with the simplicity of a dual coil build, so it’s cool that CoilART has included the optional deck – it’s a nice kit for around 30 bucks.

If you like RTAs, the Azeroth is a well made, nice-looking tank, that performs great at mid range wattage. It’s not a cloud machine, but gives good vapor and flavor without spitting or leaking…as long as you do your part.

hey there, i have problem with leaks, any suggest?


It can be any number of things that cause an RTA to leak. First thing to check is that all of the o-rings are aligned properly and that the tank is tight – including the top cap. I’ve had tanks leak because the top cap was loose and allowed air to enter the tank.

If everything is aligned and tight, it might be your wicking. That’s a tough one to diagnose and may require some trial and error. I would re-wick and make sure that the juice inlets are all completely covered by the wick tails, so there is no way for the juice to bypass the wicks and flow directly to the deck. You don’t necessarily have to pack the wick into the channels, just make sure they are covered by the wicks.

You may have to try several different wicking techniques before you find one that works – sometimes it’s like that with RTAs (which is why I prefer genesis-style RDTAs).

Good luck.
