Innokin are renowned for producing solid and reliable vaping equipment at an affordable price. From their iTaste & Coolfire series of mods right through to their iClear & iSub ranges of atomizers.

Recently they focused their attention to plugging a gap in the market where it comes to devices for new vapers, releasing their Endura T18 & T22 starter kits.

Now they have released a new sub-ohm atomizer in the ultra-compact form of the Innokin Axiom.

002 Axiom
Primarily a sub ohm tank the Axiom also has the facility to incorporate a two post RBA deck for both dual and single coil builds.

So that makes the Axiom Innokin’s first hybrid design atomizer. The Axiom also includes top-filling and a 3.5ml capacity tank which is pretty respectable considering its stealthy size.

Innokin’s write-up on the Axiom states that the device was designed in Los Angeles, California and created by Vapers for Vapers, so let’s see if they got it right……….!!

Build Quality & Design

The Axiom tank is quite simplistic in appearance with a clean external finish free of any logos or branding, which only appears on the stock coils & RBA section.eleaf istick pico review - Axiom Tank by Innokin

So, starting at the top, we have a very low profile fixed non-interchangeable chuff cap style drip tip which, fortunately, can accommodate your favourite drip tips by simply popping them into the top of the cap.

The drip tip is securely attached to the top section of the tank which can be unscrewed to reveal three generous sized filling ports. innokin axiom tank top fill

I had absolutely no issues removing this as all threads were very smooth.

Axiom Top
Next, we have the tank section which is primarily stainless steel with a small glass section located towards the bottom of the atomizer.

I actually quite liked this design as you only really need to see your juice level when it’s getting low.

As mentioned earlier, the Axiom utilises both stock coils and an interchangeable RBA deck.

Coils and RBA Deck

Included in the Innokin Axiom kit is a 0.5ohm stock coil which is made up of a dual coil build and very generously sized juice holes. In fact, they’re incredibly large.

The stock coil & RBA section screw into the base of the tank which has a positive pin protruding up to make contact with the coil/RBA deck. Again, all threads were very smooth and there were no issues installing or removing the coil.

At the base of the atomizer we have our airflow control ring which accommodates three 10mm x 1.5mm airholes. The AFC ring is also removable which is useful when cleaning the atomizer.

And on the bottom of the base we have our standard 510 connection with a non-adjustable silver plated pin, so not suitable for mechanical hybrids.

Axiom Base
The RBA section of the Axiom is a standard two-post design with two 2mm postholes and hex/grub screws to hold your coils securely in place and surprisingly there were no issues with these.

In the base of the deck on either side of the posts there are two 3.5mm diameter air holes which would be located directly beneath your coil(s) when installed. The deck can be built in either dual or single coil setups.

For single coil arrangements, Innokin have provided a silicone single coil adaptor which can be installed once your build is in place.

Overall I had no issues building on the RBA deck in either dual or single coil setup, albeit a little on the compact side.

Axiom RBA Breakdown
One important thing to note about the RBA deck is the PEEK insulator under the positive post. For some reason this does not cover the entire base of the positive post and the post has a small step in its base.

I found with the device I received for the review that the PEEK insulator had been compressed so much, presumably during assembly’ that the protruding section of the positive post was in direct contact with the base section of the tank causing a ‘Hard Short’.

Unfortunately, the PEEK insulator was not salvageable but I did receive a replacement RBA deck to complete the review. Possibly just a one-off but something to look out for before using the atomizer!Axiom Breakdown

How Does The Innokin Axiom Perform?

Stock coils on the Axiom were pretty good for pre-made coils. I used these at about 30watts (they are rated for use between 20 & 40watts) and had absolutely no issue when using them. No leaking and spit-back whatsoever.

The two large juice holes provided plenty of exposed cotton keeping the coils supplied with a good flow of e-liquid.

As mentioned earlier, I had a small issue of a hard short on the first RBA deck. Something I really hope Innokin look into as I think the PEEK insulator needs to be extended to cover the entire base of the positive post.

Building on the RBA deck of the Axiom was relatively easy in single coil setup, which I personally prefer. For the review, I used 6 wraps of 26awg (0.40mm) 316L Stainless Steel wire at 2.5mm diameter, which came in at 0.39 ohms.

Wicking was the usual Cotton Candy. The review juice for both the stock coil and RBA was Jazzy Boba, 30/70 PG/VG and 3mg nicotine.

Axiom Coil and RBA
Overall, I found the Axiom to be, aesthetically and performance wise, a great atomizer.

Flavour on the RBA was quite good, and cloud production was respectable! And there were absolutely no issues with leaking on either stock coils or the RBA.

What I Liked

The Innokin Axiom is a nice compact atomizer, a great addition to any stealth setup.

Stock coils performed well with no dry hits, providing good flavour and a reasonable amount of clouds, although you won’t be entering any cloud comps with them.

For me the Axiom comes into its own when the RBA deck is installed and I have to say this little atomiser quickly became a regular on daily vape routine.

What I Dislike

Dual coil setups can be a little tricky to build on the RBA deck of the Axiom due to its size. In addition to this, when building a dual coil setup the coils on each side of the deck need to share the same post holes which can be awkward .

Also, the silicone single coil adaptor, which I had no problems with as such, but I’m a little dubious as to how this will wear over time being constantly subjected to heat from the coil. Maybe a ceramic piece would have been better.

Final Review Verdict

Pros

  • 3.5ml tank capacity
  • Good Flavour from both the stock coil and RBA
  • Top filling with three large juice slots
  • Kit includes an RBA deck
  • Triple Cyclops airflow slots

Cons

  • Very low profile non-removable drip tip
  • Silicone Single Coil Adapter – Long term, I’m not sure how this will stand up to the heat of the coil
  • Smallish RBA deck – Might be a little tricky to build on for those of us with large hands/fingers
  • Airflow is slightly restrictive with the AFC wide open (subjective)
  • Peek insulator under the positive post of the RBA deck doesn’t cover the complete base of the post and could, as I experience, come into contact with the base of the tank causing a hard short

Smoker for 25 years but now a seasoned vaper of four years. Started my vape journey on Cig-a-likes before moving very swiftly onto CE4's and Ego’s, which were to remain my preferred vaping hardware for a considerable length of time. When the infamous Nautilus clearomizer was released I move completely away from my beloved CE4 and also dumped my Ego for a tube type variable wattage device. Shortly after this I was on to RTA’s, RDA’s, VW mods and rebuilding. Recently I discovered the joys of Squonking and have become completely hooked.

innokin-axiom-reviewThe Axiom by Innokin is a good stepping stone for anyone looking to advance into the realms of sub-ohm and Rebuildable tank atomizers at a very affordable price. Alternatively, if you’re looking for a stealthy clearomizer or RTA for your day to day setup the Axiom may be a good choice.

  1. Hey mike,
    Great review but I was just wondering what u meant by the peek insulator. Ausing a hard short as I have bought the axiom but can’t get the rba to work. My mod gives me a no atomizer message and the coil master resistance reader doesn’t give me a reading either. Could my atomizer have the same problem?
    P.S. The occ coil works fine on mY joyetech cuboid

    • Hey Slyboybill,
      Thanks. The peek insulator is the small piece of white plastic looking material under the positive terminal. On the original RBA I received for the review, this had been over compressed when the deck was assembled by the manufacturer, resulting in the positive post touching the base of the RBA and causing the hard short. However I think you are experiencing a different issue. I would suggest completely disassembling the RBA deck, give all the parts a very good clean and then reassemble it, but don’t over tighten the positive pin or you will end up with a hard short. Let me know how you get on!!

      Mike

  2. Great info once again,
    Peek insulator problem lets hope it was a one off , thanks for being a honest reviewer , love the look and single coil capability… Thank you..

    • Thanks Will. I think the peek insulator problem was more than likely an isolated incident! The second deck was absolutely fine but bear it in mind if your picking one up.
