The Innokin iSub B vape tank features a 2ml capacity and is an upgrade of the earlier iSub Tank by Innokin. It has been designed for sub ohm vaping and utilizes the innovative Plex 3D coils as well as dual adjustable airflow. Compatible with a range of eliquids, we recommend pairing this device with a range of regulated mods.

The Stainless Steel construction and high-quality rainbow-tinted Pyrex Glass highlights the durability and sleek design of this reliable piece of vape hardware whilst the uniquely printed resin 510 drip tip, offers a touch of personalisation.

Featuring a twist-to-open top fill cap, refilling is an easy process, simply unscrew, refill with eliquid and reapply the cap. The iSub-B also boasts a specially designed fill shield to protect against leakage and overfilling.

Its 25mm diameter allows this tank to sit quite comfortably on a range of vape devices, with a 510 connection compatible with the majority of mods. Allowing for a direct to lung inhale, it’s dual adjustable airflow allows for increased or decreased cloud production to suit your ideal preference.

The 0.35 Ohm Plex3D coils feature advanced mesh coil technology complete with micro-grooves which in turn increases surface area for denser flavour. Featuring organic cotton/wood pulp coils, meaning you'll experience a balance of flavour and cloud creation with every vape.

Due to the coil resistance, we recommend using high VG eliquids of 70% VG or above, for best performance.

Important information about sub ohm vaping:

This vape tank is intended for sub ohm vaping. Sub ohm tanks require a greater amount of knowledge and experience to use safely. They use specially designed sub ohm vape coils that register below 1.0 Ohm resistance, for use at higher wattages.

We recommend that when sub ohm vaping, you do not use an e-liquid that has higher than a 6mg nicotine strength, this will be too harsh on the throat. Sub ohm vaping produces more vapour and because of this, an increased throat hit. You should pair tanks like this with a high VG e-liquid, that is 60% VG or higher.

Great tank (03 May 2019)

Really enjoy this tank.
You get the benefits of a mesh coil without having to run them at 70+ watts.
The airflow is slightly more restricted than a lot of other mesh sub-tanks, but it's still a comfortable lung-hit.
The only downside is the filling mechanism. This isn't a huge pain, but you have to be very careful as when you take the top-cap off it leaves your whole glass section exposed, so you need to make sure you don't knock the glass section off the bottom o-ring otherwise your juice is going to go everywhere. The plus-point to this filling mechanism is that it won't flood your coils on a refill, but I rarely have that issue anyway.
Overall, it's an excellent tank. Really nice build quality, looks great, performs brilliantly, just look out for a tank extension glass somewhere to reduce the slightly laborious refill process.
