What is a Sub Ohm Tank? How to Sub Ohm to Blow Big Clouds?

what is sub ohm tank

As soon as you begin loving your vape juice, you may want to explore more in this niche to see whether there are alternative ways of improving the experience.

It’s a common norm to find vapers moving from ordinary tanks to sub-ohm tanks as most people at their beginning levels of vaping know very little about the sub-ohm style of vaping.

Actually this is a welcome style of enjoying one’s favorite e-juice that creates huge vapor clouds. Vapers soon find themselves in this realm due to its incredible generation of cloud as well as enhanced delivery of flavor.

In a simple definition, sub-ohm vaping, also referred to as sub ohming, is a vaping style that generates huge vapor clouds. If your friend is a vaping pro and you’ve seen them blow large vapor clouds, chances are they are using a sub-ohm tank.

In vaping competitions held in different parts of the world and where vapers compete for who exhales the largest vapor cloud, a sub-ohm tank is the most commonly used vape.

For instance, in competitive vaping, professional vapers compete for who creates the largest clouds and pulls off the best vaping tricks. This’s taken as a sport or hobby and sometimes winners get cash prizes and endorsements.

What is a Sub Ohm Tank?

A sub-ohm tank is a tool/ device that uses low-resistance coils– usually below one ohm – to generate vapor clouds. They offer sufficient airflow adequate for direct-to-lung (DTL) inhalation.

Over the years, this term has been evolving with technology. Sub ohming can only be done using these types of devices. As their name suggests, these devices utilize coils whose resistances are less than one ohm. Their minimum power rating is 40 watts and can go beyond 200 watts.

Around 2014, these devices gained incredible popularity and indeed dominated the vaping world. They became almost a default standard for the majority of vaping beginners until 2016 when mouth-to-lung (MTL) came back in style.

Today, the industry is a bit diverse, with a wide variety of vapes for various styles of enjoying e-liquids. Besides the production of large vapor clouds and intense vapor delivery, sub-ohm tanks are characterized by the production of warm vapor: their high wattage combined with low-resistance enhances the generation of warm vapor, that’s loved by the majority of vapers.

Also, its unrestricted airflow enhances the cooling of the high heat generated by the coils. Its intense delivery of flavor is enabled by its ability to vaporize large amounts of vape juice at a go, enabling the taste buds to receive loads of flavor for every puff drawn.

How to Sub Ohm to Blow Huge Vapor Clouds

how to sub ohm

The act of blowing huge vapor clouds is referred to as cloud chasing. Professional vapors or cloud chasers – people who blow large vapor clouds – constantly strive to invent fresh ways of creating the biggest clouds possible; that implies the use of vapes with low-resistance coils, excellent airflow, and high wattage is used.

To achieve the best satisfying experience and safely, cloud chasers should have the appropriate knowledge and expertise. This means users should have a good understanding of Ohm’s Law as well as battery safety. If done the right way, cloud chasing is fun and enjoyable.

A sub-ohm vape mod or pen is regarded as the safest and simplest tool for enjoying your favorite vape juice. The devices feature a tank and battery in a single unit that’s user-friendly for beginners.

For an advanced and fancy experience, the appropriate combo for clouds would be a high-wattage mod coupled with an RBA (rebuildable atomizer), favorably a double-coil dripper. Also, more advanced rebuildable tanks designed for sub-ohm vaping that do not require a lot of experience to be used have been manufactured.

Tons of modern sub-ohm tanks use several mesh coils to deliver rich dense vapor clouds. Using a sub-ohm tank to enjoy your DIY e-liquids, there’re general rules that you need to take care of.

Setting the Airflow

Configuration of the airflow settings is very paramount as far as blowing vapor clouds are considered. When more airflow is created in a vape mod, it implies that the cooling capacity will be sufficient and thereof huge clouds will be blown.

More airflow results in an adequate cooling of the coil and prevent burning out of the wick. Moreover, besides preventing damage of the mod from burnt wick or spoilt coils, low-temperature assists in the condensation of the vapor into a fine cloud.

By increasing airflow into the mod, more vapor will be generated.

Adjusting the Power Settings

It’s simple, the more the power, the bigger the clouds would be. For instance, a vape mod using 60 watts will generate a bigger cloud than that one using 40 watts.

Nevertheless, it’s not that straight, when adjusting the wattage of the sub-ohm tank you should consider several factors.

Firstly, increasing the wattage causes an increase in the temperature hence the adjustment should be restricted to a particular limit. Secondly, some cloud chasers prefer hot vapor, and others like it when the temperatures are balanced.

In this case, the suggested power setting instructions provided in the manual should be followed.

Maximizing the Surface Area of the Coil

The wick should make as much contact as possible with the coil for it to generate the largest vapor cloud. It implies that coils that have large surface areas are superior to the ones with small surface areas.

Also, a large internal diameter and intricate coil built from several strands of wire indicate a big difference. Moreover, two coils instead of one can be used to increase the surface area.

Coil Resistance

The quality and quantity of the vapor generated by a vape highly depend on the coil resistance. A low-resistance coil enables quick and easy heating implying very high temperatures are achieved in a short time which is critical for the generation of favor. The size and type of wire play a very critical role as well.

In general, thick wires take a longer time to get heated up compared to thin wires. Also, different materials (heat conductors) conduct heat at different rates. The right choice for a battery – with a high rate of discharge – should be considered. Generally, batteries above 20 A are appropriate for generating large vapor clouds.

Positioning the Coils Centrally

The coils are placed at the center of the box mod or vape pen or whatever type of vape, right before the positive post, for the best performance regarding airflow and wicking. This ensures that there is an equal coverage of wick on all sides of the coil.

Best Coil Build to Blow Bigger Clouds

Cloud chasers are on a constant quest for big clouds. By building their own coils, perhaps they might wonder what the best coils are for blowing bigger clouds.

Sometimes opinions would differ depending on the subject but this one is different. Some awesome coils are well-known for this particular purpose, namely: Clapton coils, twisted coils, staged heating coils, parallel coils, and staple coils among others.

Clapton Coils

The name is drawn from the fact that they resemble guitar strings. Clapton coils feature an inner core with thicker wire and a thinner wire spiraled around it. This configuration boosts the coil’s surface area and in turn, increases not only the vapor production but also the delivery of flavor.

Vapers can build their own Clapton coils but are a bit labor-intensive. You can purchase ready-made Clapton coils or Clapton wire in spools for your vape. If you decide to build your coil, you just need to wrap it as an ordinary coil and connect to your device.

Parallel Coils

These are double coils, only that two strands are wrapped side by side and simultaneously. The final products appear like a typical coil at glance, but it’s really a dual coil with interlocked strands.

The purpose is to increase the surface area while reducing the resistance. Building parallel coils is pretty easy. All you’ve to do is wrap your kanthal as you ordinarily would and ensure the wires don’t cross.

Twisted Coils

They resemble Clapton coils except that the wires have an equal gauge. Twisted double wires increase the surface area which is very critical in vapor production.

Building your own twisted coils is pretty simple: a kanthal wire, a pair of pliers and manually twisting the wires is basically what is required. When completed, the twisted wire can be used in any kind of build.

Staged Heating Coils

These are meant to rectify the major downside to sophisticated coil designs. For instance, the Clapton coils offer superb production of vapor and delivery of flavor but take very long to ramp up. The staged heating coils correct that.

Building a staged heating coil is much similar to building a parallel coil. The wire strands are wrapped like it is done for parallel coils ensuring that they do not overlap. When complete, the coil looks like a parallel contact coil but has alternating Clapton coil wraps.

The Staple Coil

Much similar to Clapton coils with the same concept only that the outer strand is wound around various stacked pieces of kanthal making the windings appear more like staples.

This configuration is meant to increase the surface area of the coil and in turn, increase the production of vapor. Building these kinds of coils is labor-intensive but requires a lot of patience.


Today, just like football evolved from being a mere hobby to a sport and business, vaping is going the same route. Vaping competitions are held in nearly all cities across the world where vaping pros gain a massive following, money, and even endorsement deals when they meet at local clubs.
