Innokin iSub S Intro
Today I am taking a look at the iSub S from Innokin. The latest in the iSub series from Innokin. Featuring a 4.5 mL capacity, clapton coils, top fill and a new coil swapping system, could this be the tank Innokin are remembered for? Let’s take a closer look!
The iSub S comes in a nice presentation box which is tightly packed with the tank, spare coil and extra goodies cushioned by a foam insert. To keep the box nice and compact the user manual is a double sided piece of card.
I quite like the packaging. Nothing too fancy, compact, kept everything in great condition and it looks pretty good too! No complaints from me.
Design and Aesthetics
Overall I think the Innokin iSub S looks pretty good. However, the drip tip doesn’t quite sit flush, as well as the base locking into place with a beauty ring. Only the smallest of gaps but it has to be mentioned.
Also, I’m not too keen on the stainless steel swirls around the glass section. I think it would have been best to leave it clear, as there is a lot of stainless steel on show with this tank.
Vaping the iSub S
The iSub S comes with the clapton coil pre-installed. This is a 0.5Ω coil rated from 30-70w. The clapton coil vapes very well and the flavour is brilliant from the device. I do feel the wattage ratings are slightly over exaggerated, though. I preferred this tank at around 50-55w. I found at 65w, whilst not burning, was a very hot vape even with the airflow wide open.
The standard coil is again a 0.5Ω coil but rated at 20-35w. This coil vapes well with ok clouds and good flavour, not quite on par with the clapton but not far off. The wattage range is good however pushing to and beyond the 35w mark made the vape too hot for me.
I prefer to vape this coil at around 25w it’s a good balance and vapes really well! Plus, it’ll conserve juice and save your battery life!
Easy Swap Coil System
The new way of switching coils is fantastic! No more unscrewing coils just a simple pull one out and push one in. Also, the fact the coil is its own 510 pin means this tank hits slightly harder too.
Top Fill of the Innokin iSub S
This is one of the better top fill systems that I have used. No unscrewing top caps, just a simple twist to reveal two large fill holes that have fitted any bottle I’ve tried. A very clean and easy to use system with no leaking!
I don’t like how the airflow doesn’t match on both sides. On one side there is just a single Cyclops slot, on the other there is a Cyclops slot but with extra small airflow holes if you close this off.
This leaves one big issue: when I want to close the airflow off slightly, on one side it is fine. The other side exposes one of the smaller airflow holes so I’m not really closing off the airflow at all on that side.
That gives me imbalanced airflow to the coil. I would rather just have the 2 Cyclops slots or have the smaller airflow holes on both sides not just one.
There are a few parts of the device which don’t sit flush. Firstly, the drip tip doesn’t sit flush on the device, then the base doesn’t sit flush with the beauty ring. Whilst none of these are major, they are noticeable and it annoys me! I like my tanks to sit flush.
Also there is too much stainless steel for my liking. The tank seems quite bulked out with SS at the top and bottom, so to make that look better Innokin have added yet more SS around the tank section. NO! Just leave the tank to be the Pyrex glass. If I wanted an all stainless device, I’d buy a dripper!
Overall this tank performs very well, whilst aesthetically it isn’t very pleasing to me. But, that is something purely subjective and others may like the styling.
The performance is great, though! The Clapton coil vapes really well with plenty of flavour and vapour production. Sufficient amounts of airflow and the tank doesn’t get hot.
The iSub S is only $19.99, which is a bargain for the quality and vape you get from this solidly performing and very affordable sub ohm tank.
