Innokin Zenith Tank | A Hassle-free MTL Tank

Innokin Zenith Tank intro

The Zenith tank is the latest release from Innokin’s Platform series, a collaboration with Phil Busardo and Dimitris Agrafiotis. According to the team, all products coming from the Platform series are designed to help smokers make a transition to vaping, and the main points of focus are ease of use and safety.

Busardo is one of the most well-known product reviewers on YouTube. Agrafiotis, who also began reviewing vapes online, is better known as an advocate and host of the Smokefree Radio podcast.

The Zenith is a mouth-to-lung (MTL) tank that uses drop-in coils, and is the second Innokin atomizer they have collaborated on. The first was the Ares, a rebuildable MTL tank that has been compared to similar recent products like the Digiflavor Siren 2 and the VandyVape Berserker.

So, where does the Zenith stand in a market which has been ruled by the Aspire Nautilus series for a long, long time?

Price: ~ $30
Colors: black, stainless steel, red

Notable remarks

Aesthetics

Let’s get this out of the way: the Zenith is not going to win any beauty pageants. It is not by any means an ugly tank, but it’s not pretty either. It feels a little bit bulky for an MTL tank at 24.7 mm in diameter and its top cap makes it look too… square? Or not. That’s the thing about this one, I am not sure I like it, but there’s nothing really wrong with it.

The Zenith might have been the best-looking tank if it came out in 2015, but with tanks like the Freemax Fireluke Mesh Tank looking absolutely gorgeous, this one feels just a bit outdated. And the “OPEN” and “CLOSE” markings on its top cap don’t help its case.

It’s no stunner of a tank. But we’re not here for the looks, are we?

Features and functions

First things first, the Zenith has one of the best filling mechanisms I have ever encountered on a tank. The top-cap slides open with a small twist, giving way to a beefy fill slot, while at the same time functioning as a liquid flow control mechanism. And this is a big deal. The Zenith will not flood, and you will not have to use any of the tricks you have become accustomed to in order to avoid gurgling and spitting on the first draws. (I’m talking to you, Nautilus 2.) I haven’t had even the tiniest bit of leaking, and the tank has been performing flawlessly after every fill.

The main part of the tank is one piece, with only the top cap and the airflow ring being removable. One disadvantage to this design is that you can’t really take it apart to clean the tank. You’ll have to remove the coil, let water run freely within, then blow out the excess water, and let it dry for a couple hours. Another potential issue comes from the fact that the glass part of the tank is built inside the metal part of the main body. This means that you can’t replace the glass if it breaks. You either have to be careful or use a vape band.

The Zenith has five airflow holes, each with a diameter of 1 mm or so. One hole gives a smooth and slightly loose MTL draw. With it fully open, it will perform between a very loose MTL and a very restricted direct lung (DL) draw, depending on the coil used.

In the box, you will also find a thank you card with a QR code, which leads to a page with video tutorials by Phil Busardo. Thumbs up to Innokin for these videos, which will be a real help for new vapers.

Coil performance

The Zenith comes with two Kanthal coils, a pre-installed 1.6-ohm and a spare 0.8-ohm coil. Both coils are similar to Innokin’s iSub coils, with the 510 connection housed inside the coil itself. The design ensures that you can change coils without emptying the tank and messing with paper towels. You just unscrew the airflow ring, remove the old coil, place the new coil using the two notches as a guide, screw the ring back on and you are good to go. If you’ve ever used the Innokin EZ Watt kit, then you know how these coils work.

I was pleasantly surprised by both coils. I went through more than 40 mL of e-liquid on each coil and they showed no signs of slowing down.

The 1.6-ohm coil performed better on the tighter airflow options (up to two holes) between 13 and 14 watts. At these settings, it gives a satisfying MTL draw with a defined throat hit and dense vapor. Opening the airflow beyond two holes didn’t do it for me. I am pretty sure that the coil was designed with these airflow options in mind. Be prepared that the coil needs at least 1.5 tanks to break in, but after that I noticed no weird “coil flavor” whatsoever.

On the other hand, I found my sweet spot on the more versatile 0.8-ohm coil at three holes open, with the power set between 17 and 18 watts. This coil broke in faster than the 1.6-ohm one too; half a tank or so and it was good to go.

While the 1.6-ohm coil seemed to perform better with my 50/50 juices, they both seem capable of wicking up to 70 VG e-liquids without struggling. I actually found the flavor of both coils to be superior to the BVC coils used in the Nautilus series. And vapor production — though not very high on my list of priorities for an MTL tank — was better than expected. I also found that it was much easier to switch flavors on the go with these coils than it had been with other MTL coils I’ve used in the past. A couple of primer puffs and the new flavor kicks in almost instantly.

Verdict

The Zenith is the first MTL tank that caused me to raise an eyebrow since the arrival of Aspire’s Nautilus 2. In my opinion, Innokin’s new offering is an excellent option for new vapers, especially those who focus on the utility more than they do on the design. It is a more versatile tank with a better filling mechanism than the Nautilus 2, eliminating all the issues users of that tank had with flooding, leaking, and gurgling.

As things stand, the Innokin Zenith is the tank I will be recommending to smokers looking for an easy-to-use first vape beyond the typical auto-draw devices. It’s also ideal for experienced vapers who want a hassle-free stock coil MTL tank for everyday use.
