New Addition To The Innokin iSub Range – The Apex Tank

Innokin have steadily been releasing a new range of products over the last few months such as the excellent Disrupter mod and the iSub tank range, the latter of which has a new addition. That new addition is of course the iSub Apex tank.

Can it make an impact in a crowded marketplace? Lets check it out.

This tank was received free of charge for the purposes of this review. As always views are my own.

New top fill design

User manual

As would be expected from Innokin the packaging is tidy and well designed.

Design and Build Quality

First impressions of the tank are good. I’m personally a fan of clean lines and designs and the Apex definitely fits into that mould.

The tank is split into four sections that surround the 3ml capacity pyrex tank and has a good quality feel in the hand.

Starting from the top we have the top filling section, then the airflow, the main body windows and the removable base.

The tank as a unit cannot be dissembled apart from the base which conceals the coil and of course the 510 drip tip. This could be a concern for a few vapers out there as any breakage to the pyrex tank will require you to completely replace the unit.

Good news is Innokin have protected the pyrex tank with an outer P.C shell.

Personally I’ve never broken a pyrex tank and looking at the stainless steel jacket and the P.C layer the pyrex has surrounding it it’s not too much of a worry for me. I’m going to refrain testing the durability because I’m quite enjoying the tank!

The internals of the Apex tank have what Innokin calls their Prism system which is best left for Innokin to describe:

Innokin’s advanced new design, Prism Flavor+, boosts flavors to bring out the best in your favorite eliquids. The patented Prism convection airflow system draws in air through the dual, raised, adjustable intakes, down into the heated outer chamber and then back up through the vaporizer coils, delivering maximum flavor and also minimizing leakage. The interior design of the iSub-Apex Prism system further focuses and enhances your eliquid vapor, delivering an exceptional burst of flavor with every vape.

Well it sounds impressive, as for taking a closer look at the internals that’s difficult due to being restricted to what can be seen through the windows. But, if it performs as well as it reads who cares about the insides!

We will come back to the performance in the next section.

Functions

Let break down the various workings of the tank.

Coil Replacement

The base is the same as the iSub G tank in that the base plate unscrews so the coils can be slotted into the tank.

As with the previous iSub tanks I love this feature, it really is one of the most straightforward mess free ways for changing coils in any tank out there.

It’s a simple case of turning the tank upside down, pulling the coil out and slotting a new one in. This can be done with a full tank of e liquid. Simple.

Top Fill System

The ease of use goes one step further with the Apex tank when it comes to filling with juice. The top section of the tank is the ‘Solid Spin Top Fill System’.

Now I have used other brands of tank that are top fill such as the Smok TFV4 but I have to say the simplicity and execution of the Apex top fill beats that particular tank hands down.

A simple twist of the top part of the tank reveals two filling holes, glass drippers and standard 10ml plastic juice bottles fit no problem and allow for filling of the tank in a few seconds.

Simply turn again and the holes are covered by two layers of steel. There are small graphics on the top directing you which way to turn the tank but these aren’t really needed, it’s all very simple to use.

I have had this in my pocket, the right way up, on it’s side, upside down and I experienced no leaking at all. Great stuff. A seemingly simple feature that worked perfectly for me.

Airflow

The airflow ring has the same sized holes as the other iSub tanks but it sits higher on the Apex and differs to the others in that it sits over the pyrex glass.

The two holes that can be opened up to around an inch each. The ring is smooth to turn and can be rotated in any direction a full 360. Again, no issues here at all, easy to use and offers massive amounts of vapor when fully opened for those big direct to lung hits.

The latest Apex models now don’t have the airflow control on the drip tip (as seen on these pics). It doesn’t, for me, make any difference to the performance. This new design can be seen on the Apex 5ml tank.

How To Clean the iSub Apex

As mentioned the iSub Apex cannot be totally disassembled but it is easy to clean though. Remove the bottom and the drip tip and run water through. Then you can either blow air through or use a hairdryer to speed up the drying process.

Let it sit for a while then repeat to clean.

The inner Pyrex glass tank is not removable and is protected by the outer P.C. shell.

Condensation

When vaping on the Innokin iSub Apex you may notice a slight moisture build up on the inside of the protective windows of the iSub Apex; this is only condensation and it is very easy to clean. When the iSub coils are heated then the interior of the tank and the surrounding internal temperature is raised higher than the outside temperature.

The raised air-flow brings air in and down through the Prism Flavor+ system and moisture may collect on the inside of the outer protective shell.

If this happens it is not e-liquid leaking, it is condensation; your e-liquid continues to be securely contained inside the interior Pyrex tank.

This condensation is similar to what you have may have experienced in a car while driving when moisture condenses on the inside of the windows.

It is easy to clean the condensation from the iSub Apex.

Vape until the tank is almost empty or drain the remaining e-liquid then remove the bottom cap and pull out the iSub Coil.

Turn the top cap to open the filling holes being careful not to get any e liquid onto your hands as some my drain out. If you do be sure to wash your hands immediately.

Run clean water through the tank and wash thoroughly.

Shake the remaining water from the tank and place it with the bottom side down onto some tissue or a towel. shake again to remove any remaining moisture. You can speed up the drying process with a hairdryer on cool.

Allow to air dry and then replace the iSub coil and the bottom cap. Make sure it’s sealed well but not over tightened.

How Does the Innokin iSub Apex Tank perform?

In short the Innokin Apex performs brilliantly. Whatever the new patented Prism System is, it works.

I started at 20W on the Innokin disrupter with the 0.5 ohm coil which was a good vape if a little cool but for me the flavors really started to punch in the 25-27 watt zone.

I tested a few e juices. Once in a Blue Moon by Kind Juice and a couple of Beard Vape eliquids – and found the flavor spot on for my tastes.

Firing up upto 38 watts produced a gradually warmer vape with the flavor starting to tail off the higher I got and deteriorating at 40W. Which is no surprise really as the coils are at their best between 20-35W.

Dry hits? – I didn’t experience any so all good on that front.

If you are new to sub ohm vaping then please be sure you have the correct batteries and device. Check here for more info on batteries for sub ohm vaping and here for suitable box mods.

Is the Apex Tank Worth It?

I haven’t put this tank down and can’t see myself doing so for a good while. The performance, quite simply (after 2 days of chain vaping) has been superb. Flavor great, massive clouds with the airflow fully open and zero leaking issues for me.

The ease of use is a huge draw for me as well.

Some vapers may find the 3ml capacity limiting but this tank is so quick and easy to refill I can’t see this being too much of an issue.

Final Review Verdict

I found the Innokin iSub Apex tank to be a top performer with build quality to match. This would be a great bit of kit for those new to sub ohm vaping due to how easy it is to use.

While not an issue for me personally the fact that the tank cannot be broken down into replaceable parts may be an issue for some.

Other than that it’s difficult to find any real negatives. I think I’ve found my a new favorite sub ohm tank, or at least at the time of writing 🙂
