Type of Tanks and the differences.


For this article it's all about different tanks and the coils that work best within them. There are hundreds of different types of vape tanks and tank variations that are available at our vape shop and these fall into one of the two categories, which I have listed below and will go into more detail about them.

Broadly speaking vape tanks or clearomizers fall into three categories, mouth to lung (MTL), sub-ohm and Rebuildables (RDAs, RTAs). With Tobacco Products Directive (TPD Compliance) 2016, vape tanks are limited to a maximum size of 2ml.


For those switching from tobacco to vaping we recommend MTL tanks such as the One Kit vape tank as these vape tanks mimic the inhaling action of smoking. Therefore, you are more likely to switch to vaping and quit smoking all together with these types of tanks. Sub-ohm vape tanks are better for those who have quit smoking and are vaping for flavour or vapour. Rebuildable tanks allow you to customise your vaping experience with rebuildable coils and wires.

Mouth To Lung Collection

Mouth to Lung Tanks are recommended for mods or vape kits that power up to 15W (watts), and with a coil resistance of 1.0 Ohm and above

Sub Ohm Collection

Sub Ohm Tanks are recommended for mods or vape kits above 20W (watts) of power, and their coils are below 1.0ohm.

Rebuildable Collection 


Rebuildable tanks (RDA, RTA & RDTA) are recommended for those who would like to build their own coil (resistance) for better flavour and cloud production

This article will answer some of your most pressing questions around types of tanks and help you choose whether starting or upgrading your vape kit to a sub-ohm vaping kit is the right move for you. Here at UK ECIG STORE, we focus on serving customers who vape in the UK and the rest of the world, as a matter of fact, so we feel it's our duty to say, switching to vaping is one of the best moves you can do, for a couple of reasons.

Tobacco Cigarettes or traditional cigarettes are not only incredibly bad for your health, but once you read up on the 4000 plus hazardous, harmful chemicals in the smoke you inhale, you'll agree too!

With that being said, I know it's repetitive but we all know that these products are intended for the use of people kicking a habit and are not intended for the use of anyone under the age of 18, if you are pregnant or breastfeeding etc. Now that's out of the way, let's focus on the matter at hand.

One thing you should note from the beginning is that the ratio between VG (Vegetable Glycerine) and PG (Propylene Glycol) in your vape e-liquid will affect your chosen tank's performance. you can find out more about this by reading the Beginners Guide to Sub-Ohm Vaping article.

Mouth to lung (MTL) Tanks

Mouth to Lung tanks (cigarette style) is usually the starting point for most people who are looking to switch from smoking to vaping. The MTL style of tank is perhaps the most popular in the vaping industry and have a similar style of inhaling to smoking a cigarette. This is why people who are kicking the habit of smoking, find they work really well for them and also why they are called "starter kits" or "e cig kits".

The inhale style of a mouth to Lung tank would be that when the e-cigarette is used and you take a puff, the vapour would be taken and held in the mouth before then inhaling into your lungs. This style of vaping tends to work best with MTL tanks as they tend to be used at lower power and will give a harsher throat hit. The throat hit simulates the “feeling of smoking” and depending on the level of nicotine within the e-liquid, it can be increased or decreased accordingly. This makes someone's ability to stop smoking so much easier.

The coils within the mouth to Lung tanks would be any atomizer coil that has a resistance of 1.0 ohm (Ω) or above. For example, a 1.8Ω coil would be perfect for someone new to vape world as this would give a good amount of flavour and vapour whilst allowing them to ease into vaping, so to speak. The tank I would personally recommend would be the Innokin Zlide/Platform tank which has been on the market for around four years and is still regarded as one of the best, if not the best MTL tank available.

There are a lot of people (who are not new vapers) that prefer to use mouth to Lung tanks as they do not produce as much vapour as a sub ohm tank and are more sociable to use when out and about.

Direct to Lung (DTL) Sub-Ohm Tanks

Sub ohm tanks (DTL) are the number one choice for a huge amount of vapers worldwide, who are constantly searching for one of many things such as, the largest possible tank capacity, the longest coil life possible, the best flavour production and finally, the largest vapour production to name a few.

So what makes a tank “sub ohm”?

what makes sub ohm tanks

It really comes down to the resistance of the coil that is inside the tank. If the coil is below 1.0 ohm (Ω), it is considered a Sub-Ohm coil/tank. The coils would need to be used at a higher wattage than MTL coils and due to the two factors of lower resistance and higher power. The coils will heat up quicker and produce more vapour. Needless to say that this would also increase the amount of e-liquid vaporized and you will find that you will go through more eliquid than an MTL tank variant.

When using a sub ohm tank, it is normally advised to reduce the nicotine content in your e-liquid roughly by half compared to the level of nicotine you would use in an MTL tank. For example, I can comfortably use 6mg in an MTL tank however, with a sub ohm tank I would use 3mg of nicotine due to the power increase and the lower resistance. With this, I can achieve roughly the same amount of nicotine intake as I would using double to amount of nicotine in an MTL device based on the increased volume of vapour I inhale.

What is an RDA

RDAs were originally made to be used for mechanical mods only, but nowadays they can be used on regulated box mods as most now support the low ohm resistance coils.
