Kanger Subtank Nano

In this review, we take a look at the smallest tank in the Kanger Subtank family. The Subtank Nano is just 18.5mm in diameter/width and holds 3ml of e-liquid making it the world’s smallest tank capable of sub ohm vaping.
The Subtank Nano comes with two OCC coils; a 0.5ohm and a 1.2ohm one. These are the same ones as with the other sub tanks and they can be interchanged. The big difference with the Subtank Nano is that because of its tiny size, it doesn’t come with the RBA that features in the sub tank mini and the larger sub tank.

Our Thoughts on the Kanger Subtank Nano



The first thing that strikes you with the Subtank Nano is its tiny size. It is a lot smaller in height and width compared with both the Subtank Mini and the Aspire Atlantis. The Subtank Nano will fit on most larger 510 batteries as well as on mini box mods. It looks a bit silly on a mech as the tank will be smaller in width than the battery.

Functionality and Performance

We were tremendously impressed with the performance of this tank with both the 1.2ohm and 0.5ohm coils. The 0.5ohm OOC coil obviously produces a lot more vapor but that is to be expected from the sub ohm coil. The 1.2ohm OCC coil still produces great amounts vapor and is a great option for those who don’t have the right equipment for sub ohm vaping. Overall the vapor production and flavor on the 0.5ohm coil is right up there with the other subtanks.

The coils screw into the tank as they do on any of the other subtanks. As mentioned above the Subtank Nano doesn’t come with the RBA as the Mini and normal one does. The Nano is purely for use with either the 1.2 or 0.5ohm OCC coils. The RBA will not fit into this tank, so don’t try and do so.

The Subtank Nano has a 3ml e-liquid capacity which is more than that of the Aspire Atlantis. It is also smaller than the Atlantis in both height and width, which is incredible.

The airflow has been improved upon from the largest Subtank model. The airflow options give you a larger widest setting and also a setting for an easier mouth to lung inhale, which you couldn’t do on the larger model. I would still like to see a slightly tighter setting on this tank for an even tighter mouth to lung inhale, as for me it is still slightly to airy.

Kit Accessories

The Subtank Nano comes with a lot fewer accessories compared to the other subtanks. This is because it doesn’t feature the RBA, which means you won’t be needing the extra Japanese cotton and coils etc for rebuilding coils. The Subtank Nano is, therefore, a little cheaper than the Subtank Mini (roughly $6-7).

Why would you purchase the Kanger Subtank Nano over the other Kanger Subtanks?

I think the main reason you would buy the Subtank Nano is if you are looking for a small glassomizer style tank that also has the capability of sub ohm vaping. If you are not fussed about using an RBA then there is not much point spending the extra 6-7 dollars on the Subtank mini. The Subtank Nano comes with the normal 1.2ohm OCC coil which can be used on most 510 style batteries (recommended range 12-25W). This is great for people who don’t want or need to do sub-ohm vaping who also want to enjoy the amazing flavor and vapor production that the Kanger Subtank Nano offers. Those who want to sub-ohm can use the 0.5ohm OCC coil.

If you want to vape your Subtank on your Mech mod, I wouldn’t recommend getting the Nano. The Nano will look a little silly on a mech, as it is less wide than most mech batteries (see pic above). The Subtank Nano does however, look great on mini box mods, as you can see in the pic.

If e-liquid capacity is a concern for you then I would opt for the Subtank Mini or larger Subtank.

Overall   I think those who are looking for a smaller tank and aren’t interested in using the RBA, will be very happy using the Nano. Also, those less experienced vapers will be able to use the 1.2ohm coil on the Subtank Nano on their 510 style batteries like the Kanger IPOW2 (ideal range is 12-25W).
