Innokin iSub G Tank Review | Sub-Ohm Vape Tank

The Innokin iSub G Tank is the newest in the line of tanks from Innokin. One thing that is notable is that this tank has a lot of similarities with the previously release Innokin iSub tank.

There are so many similarities that you might have a little bit of a hard time choosing between the two. Hopefully after reading this Innokin iSub G Tank review you will be aware of which choice is going to best meet your personal needs.

In my opinion if you are trying to decide between the two vape tanks then you should go for the Innokin iSub G.

This is because the G has more features than the original which makes it an easy option. Plus you are going to love the extra performance that it has.

Of course if you have not previously used a sub ohm tank then you should make sure that you are familiar with the safety aspects of using this type of vape tank.

What’s New – Innokin iSub G Tank

If you are looking for the cheapest option then you might find that the Innokin iSub G Tank is a few dollars more than the Innokin iSub Tank.

One thing that I want to note here is that it is way less than $10 more so if you are looking for more features then you should just shell out the few extra dollars.

This will ensure that you can have a better vaping experience and get what you want out of your sub ohm tank.

I personally like that the Innokin iSub G Tank is made from high quality and sturdy Pyrex glass.

The previous model was made out of German made polycarbonate which some vapers prefer.

While I do not think that either material is necessarily better than the other one, there are some things that I like better about using glass. It is really just a personal preference so you can choose which one you like better.

There also has been an improvement in the tank size. That’s right, you are going to get an additional .5 ml of e-liquid space.

This is a great option for you if you are trying to find a tank that is going to make it possible for vaping for long periods of time without having to add e-liquid. I also think that the tank just looks better. The Pyrex glass seems to be a sleeker option for vaping than the PC version.

With the regular iSub you have one drip tip that is included and you have to use it.

One thing that I really appreciate about the Innokin iSub G Tank is that it features a drip tip that is removable. You will be able to use the drip tip that is included or you can purchase your own if you have something specific that you are looking for.

The included drip tip is made from stainless steel. Some users find that a stainless steel drip tip can get hot when vaping and some have reported burning their lips. I have not personally had this experience but there are some vapers that vape with more frequency than I do.

Perhaps one of the best things about the Innokin iSub G Tank is that it has a special no spill coil swap system. This means that you can swap out a coil without spilling any e-liquid.

If you are a seasoned sub ohm tank user then you know how great this is. With many of the competing tanks you will actually lose a lot of e-liquid if you have to swap out a coil when the tank is full. This is not the case with the iSub G. There is also no leakage with this tank.

Leakage is something that I just thought that I was going to have to get used to when using sub ohm tanks.

Well, not any longer. I really appreciate this and am so happy to be using a sub ohm tank that allows me to have the vaping experience that I want without worrying about leakage.

The performance of the iSub G Tank is pretty similar to that of the iSub Tank. In fact they both produce great clouds and are known for their intense and somewhat shocking flavor profiles.

Your e-liquids are going to taste delicious and in some cases they are going to taste far better than you every could have imagined.

How to Choose Between the Innokin iSub and the Innokin iSub G

Of course if you are determined to figuring out which of these tanks you want, it can be a challenge when they appear to be so similar.

I am going to share some of the things that I would personally consider when purchasing. This should give you the knowledge that you need to make the best decisions for yourself.

The biggest difference between the iSub and the iSub G is their overall appearance. I personally like the more upscale look that the G has but others prefer the simplicity of the original.

I can say that if you are looking for a more sleek design then the G is definitely going to be your thing.

Another difference between the two is that the iSub is made from German engineered polycarbonate, while the iSub G is made from Pyrex glass. Now there are a few things to consider here.

If you are someone who is prone to dropping your tank all of the time then the PC version might be better for you.

If you prefer to have one of these materials for your ideal vaping experience then you should choose the one that is made from your preference. I have personally found that the glass is more my style and preference.

I have also seen in the reviews that others have written that this is their preference as well.

Many vapers are constantly seeking out the biggest possible capacity for their tanks. If this is what you are looking for then you have got to check out the Innokin iSub G Tank because it has a 4.5 ml tank instead of the 4 ml tank of the original.

While .5 ml might not sound like a big deal, for some it is the difference between filling their tank once a day or having to fill it a second time. It is perfect for those who are wanting just a little bit more.

To really understand the differences you should check out the full review of the Innokin iSub so that you can really decide which is going to be your best bet.

Superior Flavor

The Innokin iSub G Tank has superior flavor when compared to other tanks. This is something that I feel has to be mentioned because I honestly thought that I was previously using sub ohm tanks that offered the “best” flavor.

One thing that I do want to note here is that you might actually be shocked when you check this out because the flavor profile is so different and so intense. I could honestly not believe what some of my flavors tasted like.

It was shocking that they were so delicious. I will note here that this could be a personal preference as well.

Before I had used the Innokin iSub G and Innokin iSub I would not have believed that a tank at this price point could offer me a better flavor than something that was more expensive.

To be honest, the only reason that I had been purchasing more expensive tanks was that they were able to offer me the best flavor profiles which is what I was searching for. Well, not any more.

The Innokin iSub G offers you amazing flavor profiles that you are sure to appreciate. Plus you are going to love that you feel like you are getting a great deal when you are vaping with such an affordable tank and getting those great flavors.

Final Thoughts

There are so many great things that I can say about the Innokin iSub G Tank. I really like this tank and find that I am reaching for it more often than others since I received it. It is one tank that offers you superior flavor profiles which I personally appreciate.

I also appreciate that Innokin has put together some kits that feature this tank with one of their high quality mods.

So if you are new to the vape tank reviews world this could be a great first sub ohm tank purchase because you actually get everything that you need to start off on a great vaping experience.
