Innokin iSub G Intro

In this article we review the Innokin iSub G sub ohm tank. I won’t be going into very much detail in this review as the iSub G is very similar to the Innokin iSub that we reviewed in depth a few days ago. Check out the iSub review for more information. I will point out the major differences between the iSub G and the normal iSub below and why you would get the iSub G tank over the original.

Notable Remarks

Differences between the iSub G and the iSub PC

So the iSub G is around $5-9 more expensive than the iSub with the German PC tank, so let’s take a look at the differences and why you would or would not get the iSub G over the normal iSub.

  • Price: iSub G is $5-9 more expensive than the iSub with the PC tank
  • Pryrex Glass Tank: The iSub G comes with a Pyrex glass tank instead of the German polycarbonate one on the normal iSub
  • Tank Capacity: The Pyrex tank on the iSub G has an extra 0.5ml tank capacity at 4.5ml compared to 4ml on the original
  • Aesthetics: The iSub G has the Pyrex tank and instead of the PC bell shaped tank featuring a stainless steel top cap, which is my opinion looks slightly more sleek than the polycarbonate one
  • Stainless Steel Removable Drip Tip: The drip tip on the iSub G is removable so you can use your own drip tips, whereas the normal iSub drip tip cannot be removed

Performance of the Innokin iSub G

The iSub G uses the same 0.5ohm coils as the PC (polycarbonate) version, so it vapes exactly the same. If you want to read more about how it vapes head over to our iSub review.

As we mentioned in the other review, we were really impressed with the performance of the iSub and were impressed with the iSub G as well. The iSub G vapes very well and provides fantastic flavor. The iSub G also features the no-spill coil swap system which is a neat little feature allowing to swap coils easily without any leakages and spills!

Should you get the iSub G or the iSub with the PC tank?

So the big difference is the Pyrex tank and the overall aesthetics of this iSub G. I think a lot of people might prefer the looks of the iSub G, as in my opinion it looks slightly more elegant. Apart from the aesthetics there isn’t much of a difference apart from the extra 0.5ml of e-juice capacity and the removable drip tip. Does it warrant the extra $5-8? Yes and No, as it will come down to your personal preference and if you like the bell shaped PC tank on the iSub versus the more elegant Pyrex glass and stainless steel finish on the iSub G. I dropped our PC tank on the other iSub and it didn’t break and have been told it is more durable than Pyrex. I doubt the Pyrex tank will survive a fall! For me the price point on the iSub tank with the PC is a reason why I would get that tank over the iSub G, as it is so affordable. The iSub G is still very affordable and at the lower end of the sub ohm tank price spectrum, so if you prefer its looks then I think it is a good affordable sub ohm tank that works well and provides massive clouds and great flavor.

As I said in the previous review the flavor and clouds are right up there with the more expensive tanks. It isn’t quite as good as the Crown, Atlantis 2, Freemax Starre, Herakles, but it isn’t far off. For its very low price point that is very impressive and makes both the iSub G and the iSub PC good buys, depending on what you prefer aesthetically and price wise.

Overall we really like the iSub G and think if you like the Pyrex tank and stainless steel top cap more than the bell shaped PC tank, then it is definitely worth the extra $5-9.

    I picked up one of the iSub G tanks earlier today. One thing I’ve noticed is how tight you have to tighten it after filling it. It’s leaked on me twice already after filling it because it wasn’t tight enough. I think it’s because I’m not used to using a tank where the glass and top can be separated. Other than that, it’s a good tank. Purchased the G after using the plastic iSub for two weeks. Happy with both but I like to use my own tips.

    • Thanks for the info Jeff! Glad you are enjoying your i Subs.

    • Jeff Lewallen

      Update: The iSub G tank I purchased leaked out an entire tank of ejuice a total of four (4) times over a 24 hour period. I went back to my vape shop and spoke to them about it. After inspection, they found a small burr on the coil. They replaced the coil for free and gave me another 30ml bottle of my juice. The tank is performing perfectly now.

      • Thanks for the update. That’s great customer service from your vape shop!

  • Cait O’Darling

    I love the Innokin iSub G sub ohm tank performance but I am having a problem with the gasket & don’t think that Innokin offers a replacement gasket that can be purchased separate from the tank. The gasket is a flimsy clear rubber band-like thingy that seats the tank snugly upon the base and is VITAL to this tank’s performance. I have only been using the Innokin iSub G sub ohm tank for about a week & would love to continue but – with the defective gasket – it leaks so badly that it’s not possible.

    • Sorry to hear that Cait. I’d try giving Innokin a ring/email. Good luck!

  • Nathan Watts

    Sorry if this is a silly question, but since it comes with a drip tip, does that imply I can drip with it as it is?
    I thought you could only drip with certain atomizers.
    Thanks.

    • Hi Nathan. Theoretically you can, but there is no need to at all, as you have the tank full of e-liquid feeding the coil. I wouldn’t advise it either, as there might also be the risk of spit back when dripping down onto the coil . Dripping is meant for RDAs (rebuildable dripping atomizers) only. Hope that helps!

      • Nathan Watts

        Why did it come with the drip tip?

        • It is just a generalized term for the mouth piece. Not every drip tip is meant for dripping! Slightly confusing but that is how it is 🙂

  • John P. Baniqued

    I have been using both the iSub G and an ACME L and both are performing very well for me. I give the iSub G a slight edge on performance, IE, air flow control. Neither tank leaks if properly assembled. The iSub G is slightly more finicky to seal after filling but even so, it is the better of the two. I just ordered my second iSub G. thanks for ALL of the reviews and guidance.

    • Good to heard from you John! Thanks for the feedback and glad you are enjoying them both.

  • BlueLine

    Hey Chris, which would you say is a better tank, the iSub or the Atlantis?

    • In my personal opinion it is the iSub that is better. I got great flavor after the first drag and the clouds were amazing compared to the Atlantis V1. Chris thinks the same.

      • BlueLine

        Thanks Alex. Do you also think that the iSub G is almost on par with a tank such as the Crown?

        • Uff, hard one. Price wise, yes. Quality and flavor, no. The Crown is the better tank.

      • BigMoney

        Hey Alex, how does it stack up compared to a Crown in your opinion?

  • Adam

    I’ve just got a full cool fire plus kit. I’m wondering where you put the gaskets in the g tank to stop it leaking thanks

  • Waseem

    Hello,
    Thanks for the review

    I
    use the tank with wide open airflow with the original 0.5 ohm coils and its OK ,
    I tried the tank with Clapton BVC 0.5 ohm coils
    with the original mod I get with (MVP pro 3.0) and another mod (tesla nano), in both
    cases the tank become very hot after 5-7 puffs on 30 watt ( and I was
    afraid to go for 40-45 watts) and I panicked and stop vaping on it, so i just want
    to be sure , its normal and tank wont explodes/broke form this heat
    and also the mod?

    I’m very new for vaping so for that I’m not sure.

    Hope I can get answer.
    Thanks

    • Yes this is normal. Tanks tend to get warm or even hot depending on what coil you vape. Be sure to have a break if you notice the tank is getting too hot.

      • Waseem

        Thanks, actual it gets very hot from bottom and I cant touch it after few puffs.

        Its disappointing a little as I have to vape for 5-10 minutes and take a break for 10 minuets with this Clapton coil, I will go back for the original 0.5 coil.

        And I will look for a new tank that can handle long vaping session – with good flavor – clouds,

        Is there such a tank? any advice ? 🙂

        Thanks again.
