Geekvape Ammit Dual Coil RTA Review

Geekvape Ammit Dual Coil RTA Intro

After a resounding success with the single coil Ammit RTA, Geekvape has released the Ammit Dual Coil RTA. The dual coil version retains a key feature that contributed to the success of the original Ammit: the 3D airflow system. Geekvape is calling it “four-path airflow” on the Ammit Dual, but it is essentially the same concept.

Geekvape has done much more than stuff dual-coil capability into the new Ammit. The Ammit Dual Coil RTA features a 20 mm postless deck with a lot of flexibility when building. The postless deck also allows room to implement the four-path airflow system, where airflow is directed at each coil via three side ports and two ports under the coils. For those preferring a single coil option, the Ammit Dual ships with a single coil plug.

The Ammit Dual is larger in diameter than the original at 27 mm, measured at the tank, and tapers to 25 mm at the base to ensure there is no overhang on most newer mods. The new Ammit holds 3 mL of liquid and easily converts to a full 6 mL capacity using the included chimney extension and longer glass tube.

The Ammit Dual Coil RTA comes in brushed stainless steel or black finish with an ultem drip tip and 510 adapter. It also fits Goon tips.

(Fun fact: In ancient Egyptian religion, the Ammit was a female demon, a soul-eater that was part lion, hippo, and crocodile.)

Notable Remarks


This tank is a tank – and I know a thing or two about tanks after working in and around the M1, M1A1, and M1A2 Abrams Tank for 35 years.

The Ammit Dual absolutely dwarfs the original Ammit. Even in the 3 mL configuration everything about it is bigger and bolder. It’s about the same height, but larger in diameter and the 20 mm deck is massive in comparison to the single-coil Ammit.

The Ammit Dual is well machined and everything lines up as it should. The chunky top cap has some nice triangular shaped bevels to give some grip when removing, and the threads feel very good.

Finally, a perceptive reader (KillingTime) commented about the glass tank being held by a single o-ring on the bottom. It is very easy to inadvertently move the tank off the o-ring when filling causing a mess. It nearly happened to me.

The same reader also pointed out that Geekvape has now updated their website to announced that they will be including an additional top ring to secure the glass when the top cap is removed. The tank can be used with or without the ring but if you decide not to install the ring be careful to hold the tank securely in place when refilling

Installing the coils


We all love the Velocity deck for its simplicity and ease of use. The postless deck on the Ammit Dual is a bit more challenging, but it isn’t difficult if take your time and make sure that the coil legs are the correct length. Most importantly, you can’t allow the coils to touch the deck creating a short. After some trial and error, I found that the optimal leg length was about 7-8 millimeters.

After all four legs are trimmed you simply stand the two coils in the deck holes and tighten the slotted grub screws to secure. The holes are big enough to easily trap large, multi-strand wire, but I also tested a 24g single strand coil and was able to easily capture the leads behind the grub screws.

I want to stress again that you cannot allow the coils to short deck. Make sure that once your coils are securely mounted to position them so that there is no contact with the deck. Check with an ohm meter, and check again after you wick and assemble the deck to the tank. This especially critical if you are using the AmmitDual on a mechanical mod.



The first thing I want to do is build the Ammit Dual with a single coil and compare performance to the original, then add a coil and run it higher and hotter.

I install a single fused clapton into each tank, and everything else is the same: coil resistance (0.44Ω and 0.42Ω), organic cotton (from the same cotton ball), and the same juice. I have the airflow set to fully open on the original Ammit and the smallest setting on the Dual, which gives similar airflow on both tanks.

I take a 4-second vape from each at 30W.

The OG Ammit is a bit warmer due to the smaller chamber, and flavor is very good. The Dual is a shade cooler, but the flavor is still good. I expected a noticeable drop in flavor with the Dual, but I am pleasantly surprised to find it is too close to call. Similarly, vapor production and volume is about the same with both tanks. The only difference I am getting is a slightly warmer vape on the OG Ammit.

With dual fused claptons at 0.23Ω installed, I set wattage to 70 and fully open the airflow and juice flow on the Ammit Dual. My first rip is a real eye opener. It sounds cliche, but I get tons of dense, warm vapor and a blast of flavor that exceeds both the OG Ammit and a single coil in this tank. It’s fantastic. And I had no dry hits or leaks on my first build – so it seems that the Ammit Dual is not finicky about wicking.


  • Nice fit and finish
  • Big
  • chunky
  • Large deck
  • Accepts Goon tips
  • Easy to build/wick
  • Single coil option
  • Above average flavor
  • Sizable vapor
  • Fits 25 mm mod due to the base being more narrow


  • Tank moves easily while filling


Not much more to say. I love this tank.

As much as I hate to sound like a fanboy, I’m having a hard time finding fault with the new Ammit Dual. It gives very good single coil performance, and really shines with dual coils at higher wattage (go figure – it’s right in the name). The large postless deck is simple to build and really does have lot of room – my 5-wrap claptons looked puny, but performed perfectly.

The Ammit Dual is big and chunky, and looks right at home on my Lost Vape Triade in either the 3 mL or 6 mL configuration.

If you already have the original Ammit and generally prefer single coils, I would probably stick with it, but if you want the option crank up the wattage with some big, dual coils, and blow some pretty good clouds – you really can’t go wrong with the new Ammit Dual Coil RTA.

I was all set to buy one of these when it became available for purchase, but then I saw the filling method and I suddenly lost all interest. Much like the original Cleito, it’s a huge juice spill waiting to happen.

Well, we got an Ammit dual in, and the review should be coming soon.

I just want to let you know that you were correct, and I almost had a mess on my hands. If you are not careful, it is very easy to move the glass off the o-ring when the top cap is removed to fill the RTA.

Good call.

It’s still pretty great though.


According to Geekvape’s website, they will be including an extra piece in the retail version to go between the glass and the top cap, like most other tanks. Should solve the problem, and remove my reservations about buying this tank 🙂

Nice. You are going to like it – I did.

I hope you come back to read the review, and give your impression of the Ammit Dual once you use it.

Just curious why you feel that way? It’s a top fill and if wicked properly, I would think it should be OK. Is there something I’m not seeing?

I’d appreciate the input, as I have not had a chance to actually use/review the tank.


When the top cap is removed for filling, the only thing holding the glass in place is the o-ring at the bottom of the glass. One accidental nudge of the glass during filling, and the entire contents of the tank could come pouring out. As someone who suffers from occasional hand tremors, I’d rather not take that chance!

Yep that would be a mess. Thanks for the contribution. 🙂

Do you know if this will fit on my smok alien al85?

Looks like the Ammit dual and Alien AL85 are both 27mm wide, so based only on the spec, it should fit. Of course I cannot guarantee it. I just got the Ammit yesterday, but I do not have the baby Alien to actually test the fit for you.

thank you

I will be updating this Ammit preview to a review soon – so I can’t really give any opinion on it yet, but if you think you are ready to buy and the size is your only concern – personally, I would go for it.

And please come back and check out our review and post your impressions of the Ammit.
