What Is Sub-Ohm Vaping & Its Advantages?

What Is Sub-Ohm Vaping?

The resistance of a coil used in the atomisers is defined in ohms, which loosely defines the amount of current the coil will allow to pass through it. If you keep the voltage constant and reduce the resistance of the coil, the current passing through the coil will increase exponentially, making it hotter and resulting in more vapour. Generally speaking, thicker wires offer lower resistance since they have more surface area and allow more current to flow.

While the usual range is between 1.5 ohms and 3 ohms, but when you use a vaporiser whose atomiser coil has a resistance less than 1 ohm, this is called sub-ohm vaping. While it might sound very simple, it’s basically a pretty complex topic. So, let’s dig a little deeper. Advantages of Sub-Ohm Vaping

There are three major benefits of sub-ohm vaping: more vapour, richer flavour, and warmer vapour. You’ll be blowing out the biggest clouds among your friends, shaming the other vapers who are vaping at higher resistance. The flavour is so smooth and yet intense that it’s nearly impossible to go back once you have tried sub-ohm vape. Most vaping old hands love a warmer vape, and that’s what sub-ohm vaping guarantees. Don’t worry, it won’t be burn-your-lips warm, thanks to the wide airflow that brings the vape to a pleasantly warm temperature.

Approaches to Sub-Ohm Vaping:

Depending on the type of atomiser you use, there are three different options for sub-ohming.

  1. Rebuildable Dripping Atomisers
     Also known as Drippers, the RDAs are where it all started. Early vapers used devices, slightly smaller than a tank, that could be attached to a mod. These devices were equipped with coils and a cotton wick. The user had to drip e-juice onto the wick after every few puffs.
  2. Rebuildable Tank Atomisers
     RTAs are an enhanced form of RDAs that don’t need to be dripped continuously, which surely was a sheer hassle. They are essentially clearomisers with a coil built inside them. The RTAs offer the highest volume vapours, plus very good flavour.
  3. Sub-ohm tanks
    Until lately, sub-ohm vaping was nothing less than an ordeal. You’d to buy a mod (either a mech or box mod), rechargeable batteries, Kanthal or Nichrome wire, organic cotton, and whatnot. Sub-ohm tanks have made life really easy, as you can slam them on virtually any mod, that can work at 30 watts or higher, and start blowing out massive clouds. They are pretty similar to RTAs, but have disposable, built-in coils. They offer nearly the same experience as RTAs, but take convenience to a whole new level.

What Is Mouth to Lung (MTL) Vaping?

What Is Mouth to Lung Vaping (MTL)?
Mouth to lung vaping (MTL) refers to inhaling vapour into your mouth and letting it linger there for a while before inhaling it into your lungs. To vape mouth to lung, take a draw on your vape device, hold it in your mouth then inhale it into your lungs before exhaling it.

MTL is the best vaping method for most new vapers because of its similarity to smoking cigarettes. Some longtime vapers also prefer this method because the technical limitations of early e-cigarettes only allowed them to vape MTL and they got accustomed to it.

Which Device Do I Use For MTL Vaping?

Vape devices which have tanks that use high ohms coils (1.0 and above) are the best for MTL. This is because they keep the vape at a right temperature enabling them to produce a good flavor. You can use MTL with sub-ohm devices, but the vape will get uncomfortably hot, and flavor production will be diminished.

The devices made for MTL have small coils made of artificial fibers. Thus, they do not need manual wicking. These devices are best run on low wattages, preferably 15-20 watts. Using a coil with 1.2 ohms or higher guarantees that you enjoy MTL.

Can I use any strength nicotine in a MTL Device?


If you need high nicotine to feel satisfied after vaping, then MTL is the best vaping style for you. The nicotine strength to use for this vaping style depends on your needs. If you were a heavy smoker, you should go for e-juices with high nicotine and wean down gradually. This way you will avoid getting withdrawal symptoms. Generally, mouth to lung vaping requires higher nicotine levels compared to direct to lung vaping. Hence, if you do not want to vape on high nicotine juices, this method is not suitable for you.
