The Innokin Zenith Pro tank is yet another release from the popular Platform series of tanks and mods.

It’s only fitting that I review the Zenith Pro, seen as I reviewed the Zlide Tube Kit a few weeks ago.

Innokin Zenith Pro Tank

Founded in 2011 Innokins Catalogue consists of 8 Tanks and 20 Kits, as well as 7 pod systems.

Including the Endura series, which may not sound familiar as the tanks within. The Endura series is home to the T18 / T18II / T20 tanks – which have proven to be extremely popular tanks among starters and other mouth to lung vapers.

I gave the Zlide Tube kit, a whopping 9.5 out of 10! The flavour got a 10 out of 10 with one coil and 9 out of 10 with the other.

That’s pretty impressive.

I’ve also heard really good things about the Zenith tank.

It impresses me every time I say this: Innokin lay claim to 27 Invention Patents, 91 Design Patents, 179 Patents for Utility Models and 136 Processing Patents.

Quick math; that’s 433 Patents in 8 years! More than 54 Patents a year!

With after sales services and repair centers in the USA and the UK, Innokin are based in Shenzhen in China.

The kit was sent to me free of charge for the purpose of this review and my thoughts and opinions are my own.

What Can We Expect From the Innokin Zenith Pro Tank?

We should expect exactly what we asked for…

I personally, didn’t ask Innokin for anything but from a quick glance at their website, it’s clear that they got a lot of feedback about the Zenith and they took that into account when designing the Zenith Pro.

Some things ‘you asked for’, that they delivered:

  • Replaceable glass
  • 510 mouth piece, cross compatibility
  • Bigger Capacity, 5.5ml
  • RDL (Restrictive Direct to Lung)
  • MTL(Mouth To Lung)
  • The ability to change the coil, without losing your liquid.

So, I’ve looked at the above things and it’s a pretty high tech tank.

What I expect, and what will get this review a high sore is a great Mouth to Lung and Restrictive Direct to Lung experience, including ideal flavour and vapour production.

A pretty much leak proof tank, even when changing the coil, that is easy to fill.

BTW – a Zenith is the highest point of a celestial sphere…so the question is – is this tank a peak performer?

I think the Zenith is going to hit that mark, but lets see.

Design and Build Quality

First Impressions

Innokin Zenith Pro In Hand

It is huge! It’s no secret that when I receive a product the first thing I do is film the unboxing and then I play about. No reading anything or learning, just learning via playing.

So when I opened the Zenith Pro I presumed it was a sub-ohm tank, it’s as big as a sub-ohm tank and looks fairly like a sub-ohm tank – if you hadn’t noticed by now, it isn’t a sub-ohm tank!

It is also pretty heavy, I’ve got about 2ml of liquid in and it’s weighing at 83grams!

Lets look a little closer:

Top Fill

Usually Top Fill is a desired but simple feature. However with the Zenith Pro, Innokin have gone a little further than that.

Firstly, the top fill twists open rather than lifting or sliding.

Second of all, when you twist the top, the internal ‘shaft’ also twists, this is very intentional and serves a purpose.

When twisting the top fill cap, the shaft twists in a way that it ‘shuts off the liquid flow’.

In simple terms, it covers the wicking holes on the coil, to prevent ‘flooding and gargling’ (aka leaking).

I am really impressed at how smoothly the ‘twisting’ happens. It doesn’t snag, it isn’t stiff and it isn’t so loose that it will easily twist on its own accord.

Zenith Pro fill hole closed

Because the top fill is a twist system, if there is any debris inside the outer caps hole, when you open it the debris gets pushed into the fill port and falls into your liquid.

Innokin Zenith Pro Tank Airflow

The airflow is said to be designed in a way that allows Mouth To Lung Vaping as well as Restricted Direct to Lung vaping.

The Zenith achieves this by having a broad range of airflow settings which are able to be fully closed, 5 circular holes, 2 circular holes with a wide hole or anything in between.

The adjustment band is strange, it’s not as smooth as the top fill cap, but it feels like it isn’t suppose to be, it kind of grips a bit.

Either way, I like it, it isn’t so loose that it turns on its own but it’s also not so tight that it’s awkward or annoying to move.

Replacing Coils

The Zenith Pro Tank is designed in a way that you can replace the coil while the tank is full, without losing any liquid.

how to change the Zenith Pro coil

This idea isn’t entirely new, the Aspire Tigon tank (which comes with the Aspire Reax) has a very similar system.

It works quite simply, above the coil is a spring loaded circular block, when you remove the coil, the block is pushed down to block the ‘flow holes’.

When you push the coil back in it pushes the block and spring back up, out of the way.


The zenith Pro uses a 510 connector, which is built into the coils (no the tank itself).

So far they’ve been nice and smooth, but well cover this again in the performance section, after I’ve played about a bit more.

How To Fill The Zenith Pro Tank

Tip: when opening the fill port check there is no debris in the top hole.

If there is debris it will be pushed into the fill port.

  • 1. Twist the top cap anti-clockwise until the fill hole is fully open.
  • 2. Pour E-liquid into the fill hole.
  • 3. Twist the top cap fully clockwise to ensure the fill hole is closed and the liquid flow is reopened.

How To Change The Innokin Zenith Pro Tank Coil

Thanks to Innokin’s forward thinking you can change the coil regardless of how much liquid is in the tank.

  • 1. Remove the bottom cap
  • 2. Remove the old coil
  • 3. Push the new coil full in and twist it very slightly clockwise to hold it down.
  • 4. Screw the bottom cap on.

How To Change The Innokin Zenith Pro Tank Beauty Ring

Despite how it looks, the beauty ring actually screws on and off.

  • 1. Remove the bottom cap
  • 2. Unscrew the pre-installed beauty ring
  • 3. Screw on the new beauty ring.
  • 4. Screw the bottom cap on.

How Does the Innokin Zenith Pro Tank Perform?

I figured, it looks like a sub-ohm tank, so I’m going to treat it like one!

1.2 Ohm Z Coil

1.2ohm z coil

This coil is pre-installed in the tank and is recommended to be used at 10-14W.

Innokin Zenith Pro Tank and HIGH VG

Straight off the bat, I filled it with Juccier Strawberry Mango Crush, which is a 70VG/30PG mix.

Here is why I should probably read the instructions before using stuff. I left the liquid in for an hour before I started using it.

The first puff was OK but the second was burnt, I wrote it off.

Then I read the manual and realized the top cap (fill hole ring) should be fully shut or the liquid will be cut off from the coil.

I tried again, this time with the flow control fully open and I had a few flavoursome drags, but then I started getting dry hits (14W).

I turned it down to 10W and it handled it better. From a slow, long drag the flavour was prominent at the back of the mouth.

However the flavour does fade after 10 or so puffs.


I calmed down a little bit at this point, using Got Salt Peachy Promise; a Peach and Passion fruit Nic Salt, I set my mod at 10W and got started.

The vapour production, is much like a smoke from a cigarette if not a little less.

The flavour is prominent although it doesn’t flood the mouth.

I bumped it up to 14W and I think it’s a bit strange there’s not quite enough vapour or flavour for Direct To Lung but there is a lot of vapour for Mouth To Lung.

Being flavourless at 14W, I turned the airflow down from fully open to 5 dot holes and that was much better, greeted the back of my mouth with a great mix of Strawberry and Mango.

At 18w (which is 4w above recommended), the coil provides less flavour and tastes burnt when attempting DTL.

1.0ohm Z Coil

1ohm z coil

The 1 ohm coil is gold, I don’t think I’ve ever had a gold coil before.

Away from the dazzle, the 1.0ohm coil Is a new addition to the z coil range. It is ‘Specifically designed for RDL Warm MTL Vaping’.

It is a recommended watt range of 20-25W.


When it was time to change the coil, I had still had plenty of liquid in the tank, so a perfect time to test the anti-leaking system, we’ll talk about that later, but that does mean I first used the 1ohm coil with the Got Salt Peachy Promise.

I know Innokin say the coils are designed for ‘Warm Mouth To Lung’, but I’m starting to think, that is a desperate attempt to pass it off as a MTL when it’s not.

No matter what I set the airflow to, at 20W it seems very heavy on the throat and chest, unless you take a fast and short puff.

By doing that, you don’t get much vapour and the flavour is very low, although it is not flavourless.

DTL with the airflow fully open provides next to no flavour.

With the airflow down to 1 small hole, seems a bit hot on the chest.

Down to 3 small holes provides an OK flavour but is still a little harsh on the chest at times.

Bumped up to 25W with the airflow fully open there isn’t very much flavour, I’m quite unimpressed.

Turning the airflow down to just the small holes, provides an OK flavour but I’m still not impressed it’s certainly not prominent.

For the record I also tried 29W and there was still next to no flavour.


Finally some joy.

DTL at 20W with fully open airflow there isn’t much flavour but a nice little cloud of vapour.

Dropping the airflow down to 5 small holes provides a subtle flavour and nice to vape DTL and MTL.

Dropping the airflow down to 1 small hole provides a great MTL experience, although it doesn’t create a really restrictive pull the flavour is prominent and you get a cigarette like amount of vapour.

25W with the airflow fully open again, provides a very light taste, a little bit like a weak cordial.

Turning the airflow down to 5 small holes gives a nice prominent DTL flavour, but not quite the flavour you would get from a ‘true sub-ohm tank’.

It’s a little heavy on the chest when used MTL.

Turning down to 1 small hole is pretty heavy on the chest.


The airflow control on the Zenith Pro is very versatile and is capable of providing a great DTL airflow, although I think it is a bit too much airflow for the capabilities of coils.

It also goes all the way down to 1 small hole, which is great, but if you’re looking for a really tight draw, you’re out of luck.

It is restrictive but not so restrictive that DTL isn’t possible – perhaps a smaller hole at the end would work a bit better.

Innokin Zenith Pro Tank Coil Life

After 7 days on each coil they’re still going strong.


I trust the Zenith Pro, that might sound weird but I do.

It feels study, the glass is replaceable, the drip tip fits nice and firmly, what more can you ask for?

I can’t see anything that could or would break.


There is none, there hasn’t been any leaking, including while changing the coil.

Innokin Zenith Pro Tank Liquid Shut Off System

As I’ve mentioned there is two systems at work deep inside the Zenith Pro.

First of all there is the liquid flow cut off when you’re filling the tank.

I don’t see the need for this, I’ve never had a tank leak because I filled it.

And I found myself constantly checking it was open, although I suppose that is because I’m not used to using the system.

After all, it’s not too loose, that it moves on its own accord.

Second of all, is the coil replacement system, now here is a strike of genius, although it is not a new idea, it is very useful and very effective.

It works well and takes the inconvenience out of having to change the coil while you’re out and about.


  • Huge e-liquid Capacity
  • Top Fill
  • Can change coil when tank if full
  • Replaceable glass
  • Good range of airflow settings


  • Not great for DTL
  • It’s huge
  • Doesn’t provide a really tight draw

Final Verdict

Truth be told, I feel a little bit let down.

I feel it’s unnecessarily big and they tried to cater for MTL and DTL vapers alike – but ended up landing somewhere in between.

I’m a DTL vaper through and through but the Zenith Pro is nowhere near as good as the Zlide tank.

I’m just being honest.

There will be people that really like this tank, but like I’ve just said Innokin give the impression that this is going to be a great All In One device, but I don’t think they achieved that.

Yes it provided the ‘ideal vapour’ that I said I was expecting, but I felt that I had to look for it.

Improvements? Make the end hole smaller to allow a true MTL experience, then scrap the 1ohm coil or improve it to produce a good DTL Flavour.

Vaping since (2012), back when choice was limited. I was rebuilding my RDA and powering it with the awesome the Vamo V2. In 2019 I’ve opened a “Brick and Mortar” vape shop, a Vaping Mystery Box service and launched a YouTube channel that’s already gained 500 followers. Between Vaping and family, i don't often have a second to spare. My YouTube subscribers have already dubbed me “brutal”. What can I say? I’m here to do honest reviews, not a sales pitch.

innokin-zenith-pro-tank-reviewI dropped a point off of design for not having a tight draw setting. Other than that, the deducted points are purely down to the flavour of the 1.0ohm coil and the attempt to call it a MTL and RDL
