In for review today is the Geekvape Z MTL tank.

Geekvape MTL Z tank hand check imageIt’s been a hot minute since I reviewed a stock coil MTL tank and who better a manufacturer to cast my beady eye over than Geekvape?

Shenzhen based Geekvape have established themselves as industry giants over the last seven years. They’re responsible for some of the best known Mods, sub ohm tanks and RTA’s (rebuildable tank atomizer) on the market.

We only have to look at the popularity of the Aegis Legend Mod, Zeus sub ohm tank and Zeus X Mesh RTA to understand why Geekvape are currently serving over 30 million customers worldwide.

Quite recently Geekvape decided to unify the brand image and business strategy of the Zeus range of products. They’re now simply known as the Z range.

The letters that form the word geek are derived from the words Genuine, Enthusiastic, Expert and Knowledge. It’s time to find out just how geeky the Z MTL tank actually is.

What Can We Expect From The Geekvape Z MTL Tank?

BTW the term “MTL” stands for “Mouth To Lung” which is a style of vaping generally preferred by ex-smokers. We tell you more in our Guide to Vape Styles.

Geekvape MTL Z Tank bannerThe Z range are classed as ‘the ultimate leak proof tanks’. That’s because the airflow structure is incorporated into the top of the tank. Since the e-liquid level falls below this there’s very little chance of juice escaping.

The tank is brand new to the Z range and therefore comes with two new ‘A’ series coils. (That’s another letter to remember!). These have been exclusively designed for use with the Z tank to provide a better MTL flavour experience.

It looks like the Z MTL tank is TPD compliant (EU) and holds a maximum of 2ml e-liquid.

It comes in a choice of metallic colours and these are Stainless Steel, Gunmetal, Black, Blue, Rainbow and Gold (under review).

What’s In The Box?

It comes in the usual Geekvape slip case/two piece plastic carton for added protection. The tank sits in a thick foam inlay underneath which are the essential extras.

Geekvape Z MTL Tank – Design and Build Quality

The version I received has a smart brushed Gold finish from top to bottom. Weighing 70g, it’s a little heavier than I anticipated and that will have a detrimental effect on the Mod you decide to use.

Put simply, the A series coils are so low powered the Z tank is likely to be as effective on a lightweight integrated battery Mod as a single 18650 device. This may make it feel top heavy so weigh up your choices when pairing.

..Nice play on words, eh? lol

The silica glass section is protected by a metal housing with two rather apt ‘Z’ shaped viewing windows to add that extra touch of class.

Airflow Adjustability

I’m not quite sure why the tank requires dual airflow adjustability since it’s touted as a MTL device. The chances are we’re looking at a tank capable of a Restricted Direct Lung (RDL) vape too but we’ll soon find out.

Two drip tips have been included (replaceable with one of your own) but they both appear to be identical. It would have made sense to have one for each coil resistance.

The domed top cap has some decent knurling and uses a simple quarter turn system to remove or replace. It’s very easy to work and the O-rings on the underside provide an adequate seal.

Fill Ports

Unscrewing the top cap reveals two kidney shaped fill ports measuring around 10mm in diameter. I’d be a bit cautious when filling with larger bottle nozzles. There won’t be any issues using standard 10ml bottle nozzles.

The Deck Section

There’s more than enough threading on the deck section although tightening and loosening does create a few ‘squeaky mice’ moments. It’s worth mentioning that the base tapers down to around 20mm – the main body itself measures 22.4mm.

The Z tank comes with the 0.8ohm A series coil installed and both coils have a flat edge. Although it doesn’t seem to matter how it’s fitted (plug and play) I lined the edge up with one of the two air flow separator tabs as shown below.

510 Pin

The 510 pin is gold plated and protrudes. It’s designed to work on the majority of Mods but please don’t use with any kind of mechanical device or hybrid Mod. One possible pairing might be the Geekvape Aegis Mini with its integrated 2200mAh battery.

As already mentioned, the tank is relatively heavy so devices running up to 50W may not feel right when partnering.

Geekvape MTL Z Tank – Quick Start Guide

This really will be a quick start guide because other than letting e-juice soak into the cotton it’s very basic.

Let’s assume the coil doesn’t come installed.

  • Unscrew the deck by turning clockwise
  • Push the plug and play A series coil up inside the tank chamber ensuring a snug fit
  • Installing an A series coil on the Geekvape MTL Z tankScrew the deck back onto the tank
  • Unscrew the top cap by turning anti clockwise
  • Gently pour E-liquid into one of the fill ports, keeping an eye on the fill level
  • Filling the Geekvape MTL Z tankScrew the top cap back into place

As mentioned, let the E-liquid soak into the wicking ports for around five minutes before attaching the Geekvape MTL Z tank to your preferred Mod.

NB: It’s worth mentioning that all Mods/battery sections are different. Please remember to set wattage to suit the parameters of the coil before vaping..

Geekvape MTL Z Tank – How Does It Perform?

I began by using the installed 0.8ohm A series Kanthal coil. It has a power range of between 12 – 16W so I opted for the highest power setting when testing. 88 Vape Raspberry Ripple e-liquid was used and has a ratio of 50VG/50PG.

0.8ohm A Series coil

As expected with the airflow wide open, there was nowhere near enough restriction for a satisfactory MTL vape. It’s possible but extremely loose and most of the flavour gets muted by an over abundance of vapour production.

It’s best to employ an RDL (Restricted Direct Lung) style with this setting because the airflow is restricted by around 60%. RDL vaping happens to be my preferred style and the Z tank didn’t let me down. The inhale was smooth, turbulent free and generally very quiet.

Flavour replication was excellent, bringing out all the sweetness and sharpness of the fruit while the diary like qualities blended seamlessly into the background. The flavour is there from the beginning of the inhale and well after the exhale too, lingering nicely on the palate.

This was when I learnt how precise the adjustable airflow system of the Z tank really is.

The airflow restriction was now at around 80%, a significant enough jump from when wide open. With two airflow slots open either side I was straying into MTL territory.

..but not quite.

I still felt there wasn’t enough restriction for a decent MTL vape. It’s certainly possible this time but just a tad slack for my own personal liking. In other words I didn’t feel it was offering the classic tight restriction that a cigarette butt offers.

..yes, unfortunately I do still remember! lol

The flavour was still excellent if slightly muted and a little washed out when compared to a restrictive direct lung hit. An RDL pull was now beginning to vex the neck muscles therefore making the vaping experience somewhat on the uncomfortable side.

So I was stuck between a vape and a hard place on this setting and was the least favourable in my opinion for comfort or style of vaping.

Maximum Airflow Restriction

This is where it’s at for that classic MTL vape! Airflow restriction is set to around 85 – 90% and works an absolute treat. The option of any kind of RDL vape is out the window and makes way for the true capabilities of this tank.

As well as being the perfect MTL draw there’s also a very comfortable and natural feel to the inhale. Both smooth and turbulent free, the full force of the Raspberry is able to run rampant throughout the course of the vape.

The sweetness and bitterness of the fruit join forces with the dairy content on the way out while vapour production is thin and wispy – suitably stealth like.

The proof of the MTL capabilities dawned on me after a few hours of use. I never once felt the urge to revert to my own particular style of vaping. Awesome work!

1.2ohm A Series Coil

To test the coil I used Original C Ice Blast e-liquid. It’s another 50VG/50PG blend with 3mg freebase nicotine. This A series coil runs between 8 – 12W so I opted for the latter in the hopes of maximising flavour.

With airflow wide open the restriction isn’t too far off a decent MTL vape but again, not quite the finished article. However it’s a tighter vape on this setting than the 0.8ohm coil.

Attempting a RDL vape proved to be a little bit uncomfortable but still possible.

The flavour quality was off the scale with plenty of natural tasting Menthol piling in right from the first inhale. The cooling effect on the throat was very welcome and refreshing.

The MTL vape experience starts to come together with two airflow slots exposed. The inhale is extremely quiet and turbulent free. I was very impressed by flavour definition from such a low powered coil and the cooling Menthol seeped through on every exhale

Vapour production is suitably stealth like and effective enough to replicate the experience of cigarette smoke.

Maximum Airflow Restriction

As good a MTL vape as I could’ve expected! There’s just the right amount of tightness on the draw because extended inhales are still possible. The flavour becomes more intense and saturated once the tightest of restriction is set.

This setting provides a very smooth and comfortable inhale while the exhale takes care of the business end of flavour replication. With only one airflow slot open either side you can expect the very best concentration of flavour.

There’s no inconsistency to the wicking properties of the coil, either. No additional post vape wetness or mid vape dryness just a high quality vaping experience.

Your ‘classic’ MTL vape with the airflow restriction pitched perfect.


  • Excellent flavour replication from both A series coils
  • Tough, durable build quality with good use of knurling
  • Precise airflow system
  • Easy to refill in a hurry


  • Not strictly a MTL tank
  • Slight gap between deck and tank (subjective)
  • Both drip tips are the same (subjective)
  • Coils weep from their base
  • May be top heavy when paired with some Mods

Final Review Verdict

I recommend using juice ratios of either 50VG/50PG or 60VG/40PG when using the new A series coils. I can’t stress this enough but when pairing with your chosen Mod please do make sure you make appropriate changes to wattage before vaping.

Not all chipsets have the ability to auto adjust to the coil parameters and this will undoubtedly lead to early dry hitting, potentially ruining a brand new coil.

..You’ve been warned! lol

In all fairness, the 0.8ohm A series coil still falls within sub ohm vaping territory so I guess retains its flexibility to vape as either restrictive lung or as mouth to lung.

Just remember to reduce airflow to a single slot either side if you purchase the tank for its intended purpose when using this coil.

You won’t notice such issues using the 1.2ohm A series coil. The differences are subtle but noteworthy. It’s testament to how precise the adjustable airflow really is because this is the coil to use if you’re solely into your MTL vapes. It won’t disappoint.

In closing the new A series coils match the overall build quality of the Geekvape Z MTL tank. Highly impressive in equal measure.

My name is Neil and I've been a keen vaper for eight years, having been smoke free since 2014. That's all thanks to being introduced to a CE4 clearomiser by a work mate. In 2015 I started a Facebook group encouraging members to help others make the switch, sharing thoughts and opinions while acknowledging all the hard work that goes into running a vape shop and the guidance those folks give. I've also created a You Tube channel, Ncboreas Vapes. It's primarily there to help the newer vaper so if you've any questions feel free to drop by! There are so many positives to vaping and absolutely none to smoking. It's a message I continue to spread. Long Live Vaping. Live Longer Vaping.

geekvape-z-mtl-tank-reviewGeekvape have done it again! A new MTL tank and a new pair of coils to suit. Both represent the care and attention we've come to know from this highly popular vape manufacturer. The tank is solidly built, easy to use and the A series coils are bursting with flavour. The way I see it, being able to RDL vape is just an added bonus.


    • If you are in the UK TECC have them in stock here if that helps? But I do see your problem – they are out of stock in most places.

      I am struggling to find info on this tank as it appears to have been discontinued and doesn’t even appear on the Geekvape Website!

      Geekvape do have a compatibility chart here but it just says the A series are only compatible with the Z MTL tank.

  1. Aren’t you a bit late to the party with this review? If I remember right, this tank got released by the end of september 2021…almost a year ago.
