Let me lead off this review of the Innokin Plex sub-ohm tank with an apology – I could SWEAR we took care of this back when we reviewed the Plexar mod kit, but like so many things on this warzone of a desk, it got overlooked. But maybe it’s for the best.


Why? Because our initial impression of the Plex was iffy at best. We enjoyed the initial round of flavor and were fine with the vapor production, but when compared to the advertising claims – “longer-lasting” being the most notable – we were left a little nonplussed by the whole thing.


Well, time is a funny thing. Maybe the Plex tank isn’t going to win a boatload of awards, but after spending a little more time with the tank, its coils and its cross-compatibility with the older Scion heads, I found the Plex to be a solid, reliable performer – and for its target audience, that might be more than enough to justify a purchase.

Let’s check out a section from the official description of the Innokin Plex from Vapor Authority.


At the heart of the Innokin Plex Sub-Ohm Tank stands the next-generation Plex 3D Mesh Coil. As every vape enthusiast knows, atomizer material and architecture levers a direct correlation with to vapor quality, and logically, the overall user experience.


First, Innokin engineers invested thousands of man-hours to concoct the most advanced, most high-quality sub-ohm tank available. Second, Innokin incorporated a larger surface area for the Plex 3D Mesh Coil — more real estate increases the contact points with your choice e-liquid, directly catalyzing richer flavors and acute undertones.

Initial Impressions of the Innokin Plex

On first impression, the Plex seems like a shorter, stouter version of most of today’s leading sub-ohm tanks. Which makes sense, since there’s really only so many ways a company can make a functioning vape tank, after all. But the color finishes are phenomenal, with the gun metal option being my personal favorite, complementing almost every mod in my collection.

The 24mm tank itself is a pretty standard affair, with a now-common bubble glass extension that raises the capacity to a still-meager 4mL. For a lot of people that’s more than enough for some casual vaping, but heavier users are going to want to have a bottle of juice on hand, since the included Plexus coils are as thirsty as they come.


Because of the bubble glass and squattier appearance, the Plex looks good on most mods – even mods designed for use with 26mm tanks or larger. This is why I was surprised that the stock coils were rated to go up to 100 watts or higher – generally, a more diminutive tank comes with more diminutive capabilities, but looks don’t tell the whole story here.


The rest of the story is filled with tales you’ve already heard. The machining, top-fill port and threading is all top-tier stuff, which we’ve come to expect from Innokin. Even the resin accented drip tip is standard fare, and does the job, though you’ll probably want to swap it out for better options.

Vaping the Plex and Plexus Coils

Black Innokin Plex Sub-Ohm Tank ReviewMy first negative impression came from the coils… before I even started using the Plex tank. Like other reviewers have struggled with, the coils have a bad tendency to get stuck on the chimney rather than in the base where they belong. This caused me (and the other reviewers) to remove the glass section to release the coil.


Naturally, this problem lessens with time, but it was a hell of a way to get introduced to the Plex tank. Thankfully things got better from there. Because the Plex is cross-compatible with the Scion coil heads (including the long-forgotten Scion RBA) there are six coil options to choose from. That said, I wholeheartedly recommend you use the mesh Plexus heads, which come in single (0.15-ohm) and triple (0.13-ohm) Kanthal mesh varieties.


Your preference will likely come down to personal taste, but I was unable to tell much of a difference between the two heads, other than the obvious perks. The triple coil head didn’t have as much longevity, but definitely ramped up the cloud production a lot more than the single variety, which was more flavor-focused.


But yes, the two experiences were largely the same – initial flavor was strong, with warm draws at higher wattages, but the flavor tends to fade slowly after a day or two, leading to a few weeks of lesser experiences until the coils give up the ghost entirely.


On one hand, you could argue that Innokin lived up to its promises for the Plexus coils – they DID last longer than many competitors, and DO deliver strong initial flavor and vapor. However, I was a little surprised at how quickly when things went from amazing to “just okay” and wondered more than once if I got a bad batch. But, after doing some due diligence on Google, I realized that my situation wasn’t uncommon, and that the Plexus series might need a little reworking before it’s ready for mass market acceptance.

Interestingly, I dug up a few older Scion coils – with similar specs – and found that they might have actually performed better, if not for as long, than these supposed newfangled coils. At the very least, they weren’t as thirsty and needy as the mesh Plexus heads, which ran through juice at a ridiculous rate – dropping visibly with every draw. With only 4mL of capacity, I spent a lot more time with a unicorn bottle than I ever expected to when testing the Plex.

Group shot - Innokin Plex Sub-Ohm Tank ReviewAnother HUGE item of note – while each of the included Plexus coils are rated for 100+ watts, I STRONGLY recommend keeping your mods set to the lower end of their stated capabilities. At higher wattages, flavor tends to suffer at the expense of heat and vapor, while the juice consumption goes from bad to ridiculous.


– Coils last a few weeks

– Leak-free experience

– Initial flavor and vapor is impressive


– Initial flavor doesn’t last very long

– Capacity is limited

– Juice consumption is off the charts

SPINFUEL VAPE REVIEW SCORESpinfuel VAPE Recommendation and Score

I realized how negative this review sounds, but despite the obvious downfalls, I still find myself turning to the Plex tank for road trips and longer nights out. Sure, I need an ample supply of juice when I do, but I also know I won’t likely need to carry a slew of extra coils, since the Plexus heads DO last a longer time, even if they don’t deliver top-tier flavor the entire time.


Overall, for those who are less concerned with pristine flavor and more about having something solid to have on hand, we can recommend the Plex. But we’re hoping the next round of Innokin tanks take things in a more impactful direction.
