In this Innokin iSub GÂ tank review, we take a look at the updated version of the highly popular sub-ohm tankÂ fromÂ Innokin called iSub.
The main differences between this tank and its older brotherÂ is a 0.5ml increase in capacity, aÂ Pyrex glass tubeÂ instead of a polycarbonate tank, as well asÂ a removable 510 drip tip instead of a non-removable one.Â Naturally, the designÂ has also changed a bitÂ â€“ the iSub GÂ sports a sleeker and more elegant look, whereas the older and cheaper iSub hadÂ a peculiar “frosted glass”Â finish for the plastic tank which we and, as we have heard, also many other vapers, weren’t big fans of.
Now, let’s dive in and take a closer look at what the iSub G has to offer.
Innokin iSub G Tank Review
What’s in the Kit?
- 1 x Innokin iSub G Tank
- 2 x iSub Atomizer Heads (0.5ohm)
Features &Â Specifications
Height:,60.2mm (with drip tip)
Tank/Tube Material:,Pyrex glass
Coils in the Kit:,2xÂ 0.5ohm
Wicking Material:,Japanese Organic Cotton
Drip Tip:,Standard 510
Compared to itsÂ predecessor, the design of the iSub G seems to us somewhat easier on the eyes. It sportsÂ aÂ simple, clean and sleek look with no unnecessary details.
On the bottom of the tank, here are two massive airflow slots. The airflow adjusts with ease, andÂ the rotating ring firmly stays in place at your selected setting.Â The iSub G also features Innokin’s No Spill Coil Swap System, which we will cover in more detail in a moment.
The iSub G has a standard 510 drip tip, which means that you can swap it with any otherÂ 510 mouthpiece you like. And overall, the iSub GÂ leaves an impression of a very solidly built device.
Also, the iSub G comes in two finishesÂ â€“ clear stainless steel and a black one. We got the clear one.
The iSub G comes with two 0.5ohm Japanese Organic CottonÂ coils; one of them is already pre-installed in the tank. As stated on the coils, the recommended wattage for these is 25W-35W.
We first tested the iSub GÂ on an Aspire Pegasus with an awesome peach & vanilla flavorÂ from Steamworks calledÂ Witching Hour. Juices from this particular line containÂ aÂ mix of 75% PG and 25% VG.
You can definitely alreadyÂ taste some flavor and feel some vapor even at 15W. Upping the power to 20W, the iSub G already gives you a decentÂ amount ofÂ clouds and flavor, and it only gets better and better when approaching 30W. I personallyÂ found myÂ sweet spot to be at 22W-25WÂ â€“ this wattage gives a relatively cool but very flavorful vape. 35W was already a bit too much for me â€“ the vapor wasÂ getting quite warm, and I also thought that a very deep and long hit might give meÂ some burnt taste at this point.
Judging by the performance of the iSub G,Â it itÂ safe to say that this tankÂ is a decent choice for those vapers who love big clouds but use relatively low-powered mods. And those who for some reason simply do notÂ want to fire a tank at, say, 100 watts.
WhatÂ We Enjoyed About theÂ Innokin iSub G
Outstanding flavor &Â airflow
The vaping performance of the iSub G really surprised us. Despite being way more cheaper than your average sub-ohm tank, it alwaysÂ delivers excellent, smooth flavor and heaps of vapor.
We think that flavor-wise, this oneÂ is not even close to some more expensive and more complicated tanks, like the Kanger Subtank or Aspire Triton. The coils perform outstandingly well, especially at relatively low wattages.Â Pure, silky taste with every singleÂ hit, period.
When it comes to clouds, the iSub G could alsoÂ easily be one of the top mainstream performers of 2015, and keep in mind that it makes all the magic happen at below 30Â watts. We assume that the excellent performance of this tank hasÂ something to do with the huge airflow slots and the quite open draw, whichÂ allows you to take some deep andÂ intense lung hits, makingÂ you want more.
Easy to disassemble
With many of the recent tanks being quite difficult to disassemble (think Aspire Triton), we love that the iSub G is so easy to take apart. You can access every single part of the tank with ease, so cleaningÂ it is definitely a breeze.
Easy coil swapping
The No-Spill Coil Swap System, which is present in all iSub series sub-ohm tanks,Â isÂ truly a great feature. To replace a coil, all you need to do is simply unscrewÂ the bottom partÂ to access the old coil,Â pull it out, put the new one in and â€“ voila! This means no more e-liquid spilling on your hands, no more screwing/unscrewing the coils,Â as well as no more need to empty the tank before this procedure. Just remember to keep the tank inverted when doing this, but that’s already pure common sense.
Great price point
The best thing is that the iSub G and the outstanding sub-ohm vaping experience it offers comesÂ with a very low price tag.Â As ofÂ December 2015, there are places you canÂ purchase it for just above $15. See theÂ box below for the currentÂ bestÂ deals on the iSub G!
Can’t forget to mention thatÂ the replacement coils also come for cheapÂ â€“ for example, you can get a 5-pack from Fasttech for around $7.

A variety of replacement coils
Although the iSub G comes with only two 0.5ohm coils in the kit, Innokin have given usÂ plenty of different optionsÂ for replacement: a 0.2ohm and aÂ 2.0ohm coil, two different Ni200 temperature control coilsÂ (0.1ohmÂ & 0.2ohm), a Clapton 0.5ohm coil, as well as a 0.4ohm Titanium coil.
At the moment, we have tried only the 2.0ohm coil, whichÂ is a well-performing, great option for less intense mouth-to-lung style vaping at 10W to 16W. We will keep you updated about how the other coils perform in the future.
One more surprise: if you’re into DIY coil building, the iSub G also has an RBA option available.
WhatÂ We Didn’t Enjoy About The Innokin iSub G
MinorÂ issues with filling
The threading of the entire bottom base of the iSub G has a habit to get stuck.Â Yes, this is quite a common issue with many bottom-filled tanks, but this oneÂ might be somewhat unhandy and tricky to open. Not a huge issue,Â but you might need to keep a towel or gloves around to help youÂ open it.
Also, you can’t reallyÂ place a dropper inside the tank when fillingÂ â€“ the gap isÂ relatively small, especially if you haveÂ some bigger droppers or bottle tips. However, manyÂ sub-ohm tanks and older clearomizers as well have the same issue, so that’sÂ definitely not a deal-breaker.
Leaking through the airflow slots
Although we haven’t experienced any leaking with this tank at all, we must mention this point, as there areÂ many users who have reported such issues online.
Again, leaking through the airflow slots is a relatively common problem for many other sub-ohm tanks as well. But it definitely shouldn’t be this way.Â If your iSub G leaks all over the place, it is not a normal occurence, and we simply recommend asking for a replacement if possible. But, if the leaks are minimal, try to tinker around it a bit and do the following: make sure the coil sits tight in its place; try an e-juice with a bit lower VG content, and check if theÂ O-rings seal your tank properly.
Coils burn out very fast at higher wattages
Of course, this definitely depends onÂ a variety ofÂ factors,Â including your vaping intensity, as well as the thickness and content of your e-liquid. However, we have noticed that theÂ standard 0.5ohm coils which come in the kit burn out relatively quickly when fired at anything above 30Â watts. For example, at lower wattages, theÂ coils lasted us for weeks, but when vapingÂ atÂ aroundÂ 30W-35W, some of themÂ gave up in just a few days.Â Let’s keepÂ in mind that this wattage still is in theÂ rangeÂ recommended byÂ the manufacturer.
However, if you preferÂ a bit cooler vape justÂ asÂ we do, 22W or 25W is aÂ perfectly fine setting for the iSub G, and there are no issuesÂ in this aspect at these wattages.
The iSub G surprisedÂ us with both its simplicity and the vaping experience it has to offer.Â And, although the changes are minor, it is a great improvement over its predecessor, the iSubÂ â€“Â we especially love the updated looks. Also, while being beginner friendly, it provides a greatÂ vape even for more experienced cloud chasers.
Not to say this is a truly innovative tank, but the No Spill Coil Swap System works great and makes swapping coils a breeze. With the introduction of iSub series tanks, Innokin have also brought flavor & clouds to a whole new levelÂ â€“Â this tankÂ produces a lot of vapor and makes your e-liquid taste even more mouth-watering.
The best thing, however, is that you can get all of the things mentioned above for just over $15. Sure, it’s a bit pricier than theÂ iSub, but stillÂ â€“ the iSub G hasÂ a simply outstanding price to value ratio. And, that being said,Â we think that this tank will be a popular choice for many vapers entering the sub-ohm gameÂ also in 2016.
