Sub-Ohm vaping, also known as sub-Ohming. It refers to vaping with an electronic cigarette that has a coil with a resistance level that is below one ohm. What does this mean to the average vape user? It’s synonymous with massive vapor production, intensely rich flavor, and a distinct style of inhaling.

A lot of regular vaporizers are have a resistance in the 1.5 to 3 Ohms range (they are above Ohm).O the resistance is on the high side. But with sub-Ohm devices, there is a reduced resistance. This reduced resistance causes the atomizer coil to heat up faster, vaporize more vape juice, produce more robust flavor and generate thicker clouds because of the increased current that passes through the coil.

But what exactly is it, how does it work, is it the right one for you and does it suit your likes and habits? This guide dives deep in Sub-Ohm vaping. Read forward and I think this article will help you a lot and you may know more about Sub-Ohm vaping.

Demystifying “Sub-Ohm Vaping”: It’s All About Resistance

The term “sub-ohm vaping” is surprisingly straightforward: it refers to using an atomizer coil (the heating element) with an electrical resistance below 1.0 Ohm (Ω). Traditional vaping coils typically ranged from 1.2Ω to 2.5Ω or even higher. Sub-ohm coils commonly sit between 0.15Ω and 0.8Ω, though extremes exist that is lower much than other type of vape.

Three Factors That Affect the Sub-Ohm Vaping Experience:

1.Coil Resistance: Going by the discourse, coil resistance is a deciding factor in sub-ohm vaping. Coils with increased surface areas conduct more current because of the lowered resistance. Thinner coils have the opposite effect because resistance and wattage output are inversely proportional.

2.Wattage: This term refers to the actual power that is generated by an electrical unit. In the context of this article, increased wattage means more heat produced, increased vapor and of course more flavor.

3.Battery Voltage: With regard to vaping, this refers to the power generated by the batteries of your vaping device. Increased voltage means higher wattage except in the event of increased resistance.

The Direct Lung (DL) Inhale: The Essential Technique

Sub-ohm vaping and Mouth-to-Lung (MTL) inhaling (like smoking a cigarette) are fundamentally incompatible. The sheer volume of vapor produced requires a Direct Lung (DL) inhale:

Draw: Inhale the vapor directly into your lungs, similar to taking a deep breath. It is similar to the cigarette.

Airflow: Sub-ohm tanks feature wide-open airflow control rings. Fully opening these allows the high volume of air needed to cool the powerful coil and produce smooth, voluminous vapor. Restricting the airflow too much on a high-power sub-ohm coil leads to an uncomfortably hot, harsh vape and potential burning.

Right Vaping Devices for Sub-Ohm Vaping

Not all vape devices can be used for sub-ohm vaping because of the requirements (coil resistance) needed for the special kind of vaping that sub-ohming is. Here are some devices that emit sub-ohming.

1.Sub-Ohm Tanks: they are made of two materials: the stainless steel and the glass. Of course their coils are low resistance and are commercially produced and disposable. These tanks are meant for vape users who cannot build their coils but want to experience sub-Ohming. One example of such a tank is Vaporesso skrr tank, NGR tank,Cascade tank.

2.Rebuildable Tank Atomizers (RTAs)

These are vaping tanks with rebuildable decks. Users have to build their own coils which must be within the tank. Vape juice is stored in this tank so there is no need for dripping. An example is the Coil Master Elfy RTA.

3.Rebuildable Dripping Atomizers (RDAs)

These devices simply consist of a customized coil and cotton which the vape user wraps around the coil. There is no tank as the vape juice is dripped onto the wick until it is saturated. Vaporess Delta is one example.

Maintenance is Key

1.Regular Coil Changes: Sub-ohm coils work hard. Replace them when flavor diminishes or tastes burnt (typically weekly to bi-weekly, depending on usage/sweetener content).

2.Cleaning: Regularly clean your tank (disassemble, rinse components in warm water) to prevent residue buildup affecting flavor.

3.Battery Care: As above the inspect wraps, use a quality charger, store safely.

Going by the increasing demand for “specialized” vaping materials and sub-Ohm tanks, it is safe to say that sub-Ohm vaping has become more popular than traditional vaping. It is easy to see why after all: rich, robust flavor, a hit that is stronger than the regular hit, and most importantly the capability to create thick clouds like an old locomotive train. Like every other thing in life sub-Ohm vaping has its drawbacks (costs and safety issues) which can also be negotiated with the right approach. So now that you have a better understanding, is sub-Ohm Vaping right for you? Do you have any experience about sub-ohm vaping? Leave the comments and we can talk about it.
