Hello folkeroonies! Innokin has sent out their newest product, the EZ Tube Kit which also comes with their brand new Zenith tank. The Zenith Minimal follows a very long line of tanks starting from the original Zenith, all the way to their newest iteration before the Minimal - the Zenith Zlide Top which I was a huge fan of. Like with all of the previous Zenith tanks, this one also utilizes the wide range of Innokin Z-coils which is nice for those that have plenty of Z-coils in stock. I for one, am one of those people.
Innokin has been working on products with a smaller profile for some time, being that the market has shifted in the direction of pods. The EZ Tube Kit does a very good job of falling in line with smaller pod kit products, but this is not a pod kit which makes this even more appealing to me being that the mod is useable with any 510 tank. Proprietary products annoy me, and that's essentially what pod kits force you into. So even if you find yourself not enjoying the new Zenith Minimal tank as much as I have, you can always fall back to one of your good ole favorites.
Before we get into this too far, I want thank Alisa and the Innokin team for supplying the EZ Tube Kit for review and I appreciate their patience in getting this review out. As always, this critique will be conducted in a fair and honest manner. For a better visual presentation, I highly recommend taking a look at the EZ Tube Kit on Innokin's website.
Alright, let's get into it!

TEST RESULTS & OBSERVATIONS:
I love when Innokin uses recycled material for the packaging. Maybe that's just the partial environmentalist in me, but I appreciate it. What you see above all comes in one kit, with the exception of the second device (black) and its box, so this is certainly a full starter kit. Being that the Zenith Minimal tank is made for MTL and RDL vapers alike, the ultem drip tip comes preinstalled, but there's a nice little accessories package inside that comes with a spare set of O-rings and 2 additional drip tips (3 total) giving you lots of options to tailor this tank to your liking.
The other accessories include a spare glass tube, a spare coil, a foot long USB-C charging cable, and some reading literature that should answer any questions you have about the coils and how to operate the EZ Tube. Other than maybe the light indicators, I don't see you needing to read too much into the manual - this mod is very easy to understand and use.
THE EZ TUBE BATTERY:
The battery mod cylindrical exterior is made of Aluminum-alloy and has a sandblasted look to it. Although the appearance looks kind of sandy, it's very smooth to the touch. It has quite a bit of shimmer when reflected in the right light but is otherwise quite tame with a touch of elegance. The EZ Tube shown here is the Lunar Grey colorway and has a much darker appearance than what's shown with the 7 other color options above. The overall weight is very light and the size is quite petite for the battery power it contains.
The front side with the fire button has a shaved-in flat surface giving your thumb or firing finger a comfortable place to rest while also allowing you to easily find the firing button if you're in the dark or are unable to look at your mod while you're driving. The fire button sits slightly raised and has a soft but noticeable clickiness to it. Directly behind the fire button on the back side of the mod, is where the USB-C port is located. A USB-A to Type-C charging cable has been included in this kit, but it's only about a foot long. Thankfully, Type-C chargers are quite common these days and the short cable in this kit should hold you over long enough to find yourself a longer one. The mod does charge at 1.2A, so make sure you're using a charging cable and power source that's strong enough to utilize this, otherwise you'll be charging at sub-optimal speeds. The EZ Tube does get a bit warm while charging, but that's fairly common and nothing to worry about. It also allows pass-through vaping for those that want to take puffs while it's plugged in.
The bottom of the cylindrical device is where you'll find the display. It sits slightly recessed from the rotating dial that surrounds it. I figured I'd utilize the wonderful videos displayed on Innokin's site and convert them into a GIF which if you saw above. The display and LED ring is exactly how this device operates. While at first glance the EZ Tube looks to be a bit primitive, I can assure you that it has pretty much all of the information you'll need to comfortably operate it.
On the top of the EZ Tube, you'll find the gold/brass-plated spring-loaded 510 pin with lots of give amidst a bunch of cave drawings you normally see on the bottom of a device. Being that the display is on the bottom, it would make sense to hide them here. The 7.77 Watt-hours is on the higher end for a device this small, and should give you plenty of vape time before a recharge is needed. At 1.2A, the EZ Tube took about an hour and fifteen to an hour and a half to fully charge from dead. This may seem kind of long, but again, you can vape while it's charging.
The EZ Tube mod does go up to 7.5V which is one of the reasons I love Innokin - they boost their chips. You can expect a very consistent performance pretty much until the LED lights red.
Operational Basics:
- Press the fire button 3 times to turn the device on or off.
- Press the fire button 2 times and wait for the wattage to begin blinking; turn the dial in single watt increments from 6-40W.
- When activated, the LED will show green when above 30% battery life, yellow when between 10% and 30% battery life, and red when below 10% battery life (battery indicator also on display)
- When charging, the LED will show red until it reaches 90% battery life, green between 90% and 100%, and off when fully charged.
- When screwing a tank in, the resistance will be shown briefly.
- While firing, the device will keep show the duration of your last puff.
If you're interested in knowing more about the EZ Tube features and light indicators, or you're too lazy to dig up the user manual from the box (;P), Innokin has conveniently provided it for you in PDF form here.
THE Z MINIMAL TANK:
The look of the Zenith Minimal tank almost reminds me of an all metal version of their Go Z+ tank which was part of the 60W GoZee kit. The main differences however, are the quarter-turn release top cap which allows access to the rubber membrane refill port along with the 3 removable 510 drip tips that are included. They've been lined up 3 abreast to show you a bore comparison and the drip tip diameters. The largest of the 3 (left) is best suited for an open RDL vape, while the smallest (right) has a choked bored with a smaller mouth fitting meant for MTL. And of course the ultem drip tip is a happy medium for lip comfort. You will notice a slight flavor difference between the 3 of them, so I encourage you to test them all out whether you're vaping in RDL or MTL.
The tank holds 4mL of juice, or 2mL if you live in a TPD restricted area of the world. The rubber membrane refill port does a solid job of sealing up the top. Other than Innokin's unique style of coils that have the 510 post attached to them there's nothing really new here, and in my opinion that's awesome. There's no need to reinvent the wheel when it already works reliably well.
The orange plug you see encapsulating the bottom of the 510 post is there to prevent a connection while in transit. I would suggest filling your tank and letting it sit for a minute or two before removing this just to ensure that you don't accidentally burn your brand new coil.
Innokin does a great job of giving you airflow options. On the left, if you rotate the airflow ring clockwise, you can seal off all but one airflow hole for a very tight MTL. And as we progress toward the right, you have quite a few options before you fully open the airflow.
There is an improvement that I would suggest on this tank, and that is to loosen the airflow ring tightness just a little bit. Once the tank is screwed into the EZ Tube, it's sort of a tug-o-war to get the airflow ring to tighten or loosen without unscrewing the base cap or feel like you're screwing the tank into the mod overly tight. I sort of wish the knurling was on the airflow ring itself, but there's an easy fix to this. If you find yourself running into this problem, unscrew the tank and give the base cap a solid turn to make sure it's sealed fairly tight to the tank. Then make your airflow adjustment before screwing the tank back into the EZ Tube.
Regardless of any miniscule shortcomings, the Zenith Minimal tank has been very solid in the leaking department which is always my main concern with bottom airflow tanks. Of the two tanks I've tested, neither of them have leaked a single drop since the start of testing which gives me solid enough confidence to stick this in my pocket or to stow it away in my lunch bag at work without any concerns.
THE Z-COILS:
Two Z-coils come in the kit, one being 0.3 ohms and the other being 0.8 ohms. I believe the spare 0.3 ohm coil is new to the Z-coil line, but I'm not entirely sure. The pre-installed 0.8 ohm coil is one of their old tried and true, original Z-coils. I bought a 50x box of 5-coil packages not long ago - that's how much I enjoy the Z-coils, and they're some of the cheaper and best coils available with regard to longevity. The 0.8 ohm resistance coils and higher may not be the most flavorful coils on the market, but that's generally the case with coils as you go higher in resistance and transition from more of a DL to MTL vape.
The main difference you'll notice between these two coils is the size of the juice ports which is what maintains the amount of juice that's being absorbed by the cotton wick. The 0.3 ohm coil is going to need a faster supply of juice since it's vaping at a higher power setting, thus the larger juice ports.
The 0.3 ohm coil has been the tastier of the two, but pushing the wattage above 30W was a bit too harsh for my liking to gain much in terms of flavor. 20-30W is my recommendation for the 0.3 ohm coil. Both coils have been lasting around 1000 puffs each which is what I would consider a good coil life. Results will vary depending on the Z-coil resistance you're using, and what kind of juice you're vaping, however.
Remember to line up the straight edges of the coil with the straight bumpers in the tank. Coil orientation is needed here to ensure the airflow holes in the coil are facing the airflow holes/slots in the airflow ring when the base cap is screwed on.
CONCLUSION:
For the Innokin Z-coil family, the EZ Tube is a perfect mod. Since the Z-coils range from 0.3 ohms to 1.6 ohms, this mod provides all the power they'll need to provide a great vape. Paired with the new Zenith Minimal tank, this is a great match with light weight and compactness to boot. Z-coils have always remained near the top in my overall coil evaluations due to their reliability and longevity. If you're looking for a solid vape, Z-coils have very seldom disappointed me.
The Zenith Minimal tank has performed solidly with absolutely no leaking what-so-ever. I've had both kits fully assembled with juice for over a month, and still no seepage. For a bottom airflow tank this is very rare to see, so kudos to Innokin for adding another reliable tank to their arsenal.
One last great point that I think makes this kit a solid choice, is the availability in using other tanks since the EZ Tube uses a 510 platform. I stuck the new Vaporesso iTank 2 on it with a 0.4 ohm coil and it fires right up. Of course the 40W max sort of limits this tube mod for lower coil resistances than 0.3 ohms, but for the size this mod is a champ. The 510 plate has a 25mm diameter, so this covers most tanks you're likely to use. We're now used to seeing so many of these smaller tube devices be pods, that it's great to have the option to use non-proprietary tanks on a smaller mod.
The bottom line is, with a device this small having the versatility of pretty much any mod for low-mid to high coil resistances has the EZ Tube punching way out of its league. I will certainly be getting my use of out of this kit.

OVERALL RATING:
9.0
And that about wraps up the EZ Tube Kit with the Zenith Minimal tank. I hope this review was informational for you in some way. I think this kit has a lot to offer if you're looking for a smaller 510 compatible device, and most certainly if you've already stocked up on Z-coils. The Innokin online store is currently down for upgrades, but you can purchase this kit from several partnered vendors.
I appreciate you taking the time to read this write up, and I hope to catch you in a later review. I will likely be dwindling the frequency of my reviews from this point forward, as I'll be more picky and choosy with what I'm reviewing. I'm not a huge fan of the pod products and disposables, and I don't see that ending anytime soon. But anyhoo...
Happy vape hoarding and thanks again!
