The Innokin Zenith MTL tank is the latest release from the Platform series and is designed by vape famous duo Phil Busardo and Dimitri ‘The Vaping Greek’.

It comes in a variety of colours and both 2ml TPD and 4ml rest of the world capacity – the latter obviously being slightly larger.

Innokin Is Known For Decent MTL Tanks – So How Does This Reviewer Designed Zenith Tank Vape?

Innokin are known for some exceptional MTL tanks indeed the T20 Prism is one of my all time favourite daily go to tanks especially when I’m out and about – that EZ-Watt starter kit is always in my pocket.

The last tank designed by these guys – the Innokin Ares – received shall we say ‘mixed reviews’ with a bit of a YouTube spat erupting between Mr Busardo and your top UK reviewer Vaping With Vic lol.

I’ll leave that there – hanging – because I’m no ‘vaping drama llama’ lol – however Vic defended himself admirably and like him I was a little confused at why his critical yet constructive review was met with a bit of a hissy fit lol.

I say hissy fit – Mr Busardo’s comment has so far received 116 replies and the spat looks set to continue…

Anyway I’m a big boy and can certainly handle any hissy fits coming my way lol – so on with the review.

This was sent to me by Innokin – many thanks – for the purpose of this review and as always my thoughts and opinions are my own and unswayed by any threat of a ‘throw your dummy out of the pram’ type situation – well I am a Brit 😉

Key Features

First up this is predominantly meant as a mouth to lung tank [MTL] especially with the pre-installed 1.6ohm coil and the airflow turned way down.

The 0.8ohm coil with the airflow open – whilst not a true lung hit – is more of a restricted direct to lung vape [DTL] more on that later.

The Innokin Zenith has an easy top fill design – simply twist the top cap to reveal a large juice port opening.

There’s an adjustable airflow on one side of the tank with 5 holes each of them reducing in size – open and close with arrows is written on the ring – I’m guessing in case you are confused as to how to er open and close!

The Zenith tank comes with x2 drip tips – both of which are 510 – one being a slightly tapered straight design whilst the other is more vase shaped – other 510s I’ve tried fit and some don’t so it’s pot luck if your favourite will fit.

The drip tip sits in a raised metal lip that has a very small bore from the none domed tank and there’s two large recessed windows to view your juice levels.

Design and Build Quality

As you might expect from Innokin the build on the Zenith is very good indeed – this is a solidly constructed tank.

2ml & 4ml versions

However on the stainless steel version I found the first dozen or so fills tricky as the ring was extremely – and I mean extremely – stiff.

After it had become loosened with use by I’m guessing the odd drizzle of e-liquid acting as a lubricant things became much easier – the black version was fine from the start.

So on mine the juice port threads were tight and a little crunchy – however the threads on the base to swap out the coil was smooth and silky.

Design wise it’s simple lines and clean looking with a minimum of fussy bits – however the addition of the open and close and arrow symbols does detract from the look – do we really need that?

Zenith is etched inconspicuously on the top of the tank [in the silver version] and slightly more obvious in other colours black and red – but to be fair it doesn’t get in your face if you get what I mean!

There’s also the Innokin name pressed or stamped into the base which looks good on all of the colour options.

The drip tip, as I’ve mentioned, sits high and fits into a raised lip that not only adds height to the tank but slightly increases the distance the vapour has to travel – so does this affect the flavour?

How Does the Innokin Zenith Tank Perform?

Ok I received the Zenith before Christmas so I’ve had plenty of time to work with it.

Despite the stiffness of the top fill ring once loosened up it works very well indeed with a generous opening.

So once filled up lets see how the Zenith vapes.

I used a 50:50 VG – PG e-liquid and found both coils wicked very well indeed – they also coped admirably with a 70VG-30PG mix.

OK let’s look at the performance of the x2 coils.

This arrived just before Christmas and I’ve vaped on it for a couple of hours a day every day since and the coils are still in a vapeable condition – so longevity wise so far so good.

Vaping On the Zenith 1.6ohm Coil

I began with the already installed 1.6ohm coil and have been using my go to tobacco flavoured e-liquid so I know the taste very well indeed.

First fill [50:50 VG/PG] and the flavour was more than a little muted – I had a feeling this was probably down to ‘break in’ time of the coil and was proved right because the flavour started to come through roughly half way into fill two.

By the third full tank the flavour was as good as I got on the higher resistant coil and to be honest it was/is a little muted compared to say the T20 prism [which I enjoy] and certainly the Nautilus 2 [which I adore].

zenith coils

However much of this is down to the power and maxing out at 14w the coil is hardly likely to be a flavour chasers dream.

For fun and science I pushed this up to a lofty 17w and then 18w and whilst it seemed to improve the flavour ever so slightly – it pretty soon started to feel as if a burn taste was imminent.

The flavour is passable but by no means the best I’ve vaped even with the airflow turned almost closed – however wide open and it’s slightly flavoured air on this coil with a reasonable amount of vapour.

Vaping On the Zenith 0.8ohm Coil

This coil didn’t take as long to break in and overall both the flavour and vapour was much better overall – especially on the larger version of the Innokin Zenith tank.

Innokin recommends vaping between 15w and 18w on the 0.8ohm coil and I found a happy medium at 17.5w.

It wicks very well indeed and the added power meant the flavour was much better – not amazing but more than passable.

zenith coil swap

With wide open airflow you can get a semblance of a lung hit – it’s a restricted one – but nonetheless perfectly acceptable to a new MTL vaper thinking of switching.

Of the two coils this one wins hands down for my style of MTL vaping – I do like a slightly airy draw and the adjustable airflow on the Zenith makes for fine tuning your vape.

Of note is when you do open the juice fill port – the chimney closes off the juice flow holes on the coil which should prevent flooding.

What I Like

I do like the unfussy clean design of this tank – it really does sit and look nice on your mod.

The top fill is excellent and the press fit coil swap – Innokin’s trademark since the iSub series of tanks – makes changing coils a doddle.

I like the fact there’s plenty of colour options and of course you can pop your own 510 drip tip on.

The price is good too – as seems to be the case with most Innokin products – coming in on average between twenty and twenty five quid – not bad at all.

What I Don’t Like

I’ve said this in a few tank reviews now – what’s with the garish open and close and arrow symbols?

We’re all adults here and can probably work out how to open and close a tank ourselves – or via the instruction manual lol.

For me it detracts from the otherwise very stylish design – minor nit-pick but a real bone of contention for me!

I’m surprised they haven’t gone down the domed chamber route too.

From my experience even the slightest bit of doming helps channel the vapour increasing the intensity of the flavour and could be why this isn’t as flavoursome as many other MTL tanks – though the bore is quite small.

Don’t get me wrong you can still get a decent flavour from this – I can just tell it’s slightly muted.

I can’t make my mind up on the raised drip tip lip either – is that just adding even more of a flavour block or am I just being a grumpy sod as per usual…

My point is had the drip tip sat directly onto the top cap my thinking is it would be closer to the tank therefore delivering a slightly better flavour – however the way the fill port works I guess the drip tip would stop it from moving…

I just feel that lip is unnecessary and losing it it wouldn’t diminish the overall look but might add that little bit of flavour to lift the tank into greatness…

Final Review Verdict

As a regular MTL vaper the Innokin Zenith is an almost tank – good but not outstanding.

Whilst style and design are important – flavour on an MTL tank is key – as is the throat hit and to some extent the vapour.

Flavour is a tad dulled for my taste – it’s better on the 0.8ohm coil and larger capacity version – as is the throat hit and vapour – so when you first vape on this I suggest beginning with the lower resistance coil.

Of the two sizes – the 2ml vs the 4ml – the chimney is slightly different [with an almost dome shape] on the larger version and to be honest the flavour jumped enough to make me enjoy vaping on that one a little better.

Break in time seems a little longer compared to the Innokin Prism so patience is a virtue with these coils 😉

I’ve always liked the press fit coil swap on the Innokin tanks and this one is pretty much the same as those and I have been able to swap them out with the tank still half full.

Though do make sure you close the fill port – I left mine open whilst taking the photos and dumped 2mls of juice everywhere lol.

So the question is if I lost or damaged this tank would I go out and buy a replacement?

I’m always brutally honest in my reviews and sadly despite the design and build quality – I still prefer the flavour off the T20 Prism tank – so no I don’t think I would.

However don’t let me put you off – it’s a good tank just not a great one!

I have simpler vape tastes these days - I never leave home without a Caliburn G, a Vaporesso Luxe 40 or Innokin EQ FLTR and a CBD vape pen or bottle of CBD drops in my rucksack...or indeed an Aspire Nautilus Prime X in my pocket... At home I'll be using various mods topped with the GeekVape Zeus X RTA or the Signature Mods Mono SQ topped with the Augvape BTFC RDA... I'm a former journalist and now a writer and sometimes author... I'm ex Army - adore dogs and never happier than hiking over the hills or with a good book on a beach.


  1. Agreed there is no flavour for any of the z coils. This is really disappointing considering such a nice design. I hope Innokin make a coil that tastes as good as the t20s 1.6 or 0.8 coils. I tried the new zlide with all 4 coils and all was a disappointment so another waste of a great tank due to flavourless coils.

  2. After 2 months with Zenith 4ml version I agree on flavor being muted. I prefer Aspire Triton 2 with 1.8 coils, and Innokin Isub Apex/V with 2.0 regular kanthal coils for best mtl flavor and throat hits. Your review was spot on.

  3. Hello sir!
    Congratulations for the review. A very detailed one without a doubt.
    I have a simple and straightforward question for you if it’s not a problem please.
    So far, I have the 5 ml Naftilus atomizer, the 2or3ml Naftilus atomizer, and the 2ml Naftilus 2.
    Because I only use Naftilus 2, I’m thinking of buying another atomizer to have a 2nd liquid there, just for a change. Do you recommend to buy Naftilus 2 again, or try Zenith? Despite its flaws, I’m happy with Naftilus 2 so far. But I’m open to try something new if it is worthy. (I use Naftilus with the 0.7 coil)
    Thank you in advance

    • Hi George,

      The Zenith is a good option as a second tank for sure.

      Another option (as you like your Nautilus tanks) that you may want to hold out for is the Nautilus 2S. This should be released any time now and should be an improved version.

  4. I want to start off by saying that I think you have the best site out there for detailed reviews and for vapers who are looking for unbiased opinions.

    I completely agree with your thoughts on this tank. I was so excited when the Zenith came out and bought it within the first hour it came on the market. I think Innokin makes the best mods and prefer MTL vaping most of the time, so this was one I was targeting.

    There is so much to love with this tank – 4ML is great, it’s much easier to fill than the Nautilus 2, and it is well-built and rugged. However you hit the nail on the head in pointing out the flavor is considerably muted compared to the Nautilus 2 and, in my opinion, even AIO kits like the Joyetech AIO and Endura series. If the flavor was more pronounced, this would be far-and-away the best MTL tank on the market. Unfortunately, I find myself going back to other tanks for when I am in the mood for MTL vaping because of the less-than-ideal flavor.

    I am really hoping enough people voice their opinions about this so maybe Innokin decides to tweak their coils to improve flavor. Perhaps that isn’t too realistic, but I’ll keep the tank in my “vape drawer” just in case.
