Sub-ohm vaping is a relatively unknown term to the uninitiated. In a nutshell, sub-ohm vaping is a vaping style that relies on using an atomizer with a resistance level of below one Ohm to produce massive amounts of flavorsome clouds.
This style usually attracts those who look for big vapor clouds, warmer drags, and increased vapor flavors. Think of the vaper who showcases vaping tricks while blowing out the biggest clouds—there’s a high chance he is sub-ohm vaping.
Allow me to give you the lowdown on sub-ohm vaping.
The Workings of Sub-Ohm Vaping
First, let’s learn how sub-ohm vaping works.
It was previously extremely important to learn Ohm’s law to adopt the sub-ohm vaping style successfully. Thankfully, with the large influx of regulated mods with prebuilt coils, the process of sub-ohm vaping is now not as complex as it used to be.
Ohm’s law implies that with high voltage and low resistance, current passes through with ease. So, when a lower resistance atomizer (heating coil) is used at a higher power level, current can pass through it with minimum obstructions, thereby helping generate more vapor.
A coil that has a resistance rating of below 1.0 ohm is regarded as a sub-ohm coil. Such an atomizer also benefits from having a large wire and wick.
In the beginning, vapers used powerful batteries to obtain higher voltage. However, they couldn’t get the desired current strength because of limitations in batteries, so they shifted focus to reducing resistance instead to get higher current.
Resistance is not the only instrumental factor for sub-ohm vaping. The size of the airflow holes and its flexibility also play an important role in determining the success of this vaping style.
Understandably, big air holes facilitate better airflow, allowing the coil and vapor to cool down. Vaping with hot vapor can be an extremely displeasing experience.
Airflow holes that boast adjustable settings can help you vape as you prefer. With bigger airflow holes, you get more airflow which helps in the production of more vapor, thus creating the ideal setting for direct lung vaping.
Regrettably, cool vapor isn’t flavorful in the slightest.
Smaller airflow holes limit airflow. However, it is the preferred setting for those who seek more flavor and warmth in their vapor.
Less airflow also results in the production of vapor with a stronger throat hit.
Vape Juices for Sub-Ohm Vape
As mentioned earlier, large clouds of vapor need to be formed for a successful sub-ohm vaping experience. Therefore, you will need vape juices that have been specifically created to produce large amounts of vapor.
Thicker vape juices with a higher level of VG (vegetable glycerin) content usually fare the best at creating massive clouds. VG is known for accentuating the sweet taste of e-liquid and for producing luscious clouds of vapor, making it essential for cloud chasing.
The general rule of thumb implies that an e-liquid should have a 70% VG / 30% PG split for sub-ohm vaping. Lucky for you, there many vape juices for clouds manufactured these days so it won’t be hard to get yourself a bottle.
When you adopt the sub-ohm vaping style, you inhale massive amounts of vapor, thus ingesting more nicotine than usual.
If you stick to regular e-liquid with highly concentrated nicotine, you will experience an unpleasant rush and a rough throat hit. To avoid such a situation, go for a vape juice with low levels of nicotine.
Although experienced vapers usually opt for 6mg, start your sub-ohm vaping journey with a 3mg nicotine vape juice.
Mods and Batteries for Sub-Ohm Vaping
Opt for a regulated mod during sub-ohm vaping. We will not discuss unregulated mods as they can be complex for a novice vaper to operate.
To use an unregulated mod (also called mechanical or mech mod), the user will need to understand Ohm’s law, battery safety and limitations, and coil rebuilding, etc. Unregulated mods also perform inconsistently when the battery is drained.
Anyway, choose regulated mods as they are safe and easy to use.
Go with a vape mod that is compatible with a coil that has a resistance rating of below 1.0 ohm. Also, ensure that your sub-ohm tank is compatible with the mod.
Sub-ohm box mods are usually powered by18650 batteries. When choosing a battery, select one that has a high discharge rate.
Why should you do that? That’s because when you lower the coil resistance, the discharge rate required for the battery goes up.
A battery with a low discharge rate would struggle to keep up with the demands of the mod going into very low resistance. In short, choose a battery with a high discharge rate for safety purposes.
If you want to avoid the hassle of picking a battery, go for a regulated box mod specifically created for sub-ohm vaping; they usually come with built-in batteries.

Thanks to the rappers in cool music videos, we’ve all been led to believe that blowing large clouds is a desirable experience. Since sub-ohm vaping offers the biggest clouds, many have now started sub-ohm vaping with no intention of going back to their old ways.
Sub-ohm vaping also attracts vapers who enjoy a warmer vape.
On the downside, this vaping style can be heavy on your wallet as sub-ohm tanks and coils are quite expensive. Let’s not forget that you’ll require more e-liquid too as your consumption will grow exponentially when making the transition from regular vaping to sub-ohm vaping.
Plus, you’d also need to make more coil replacements.
When sub-ohm vaping, keep in mind to pair branded sub-ohm vape tanks only with trusted regulated mods. Check the nicotine strength of the e-juice you use and power your mods with reliable batteries.
