Sub-ohm Vaping Explained in ABC Simple Steps

Guide to Sub-Ohm Vaping

Sub-ohm vaping, or simply sub-ohming, has virtually become the holy grail for cloud chasers. However, there are still several misconceptions about it because of insufficient information. Many new and even intermediate vapers don’t know exactly what is sub-ohm vaping and how it works. So, here’s a simple, comprehensive guide to answer all the questions you have in your mind.

Why Sub-Ohm?

Before we delve into what is sub-ohm vaping, let’s try to understand why you would want to try it in the first place. Well, the answer is very simple, and in three words it will be “massive, flavor-rich clouds”. Okay, that’s four words. Sub-ohm vape mods produce many times bigger and thicker clouds as compared to regular mods, which are obviously more flavorful and satisfying.

Understanding the Ohm’s law

Well, even if you’re are not a physics enthusiast, just bear it for a while as we explain the ohm’s law – on which sub-ohm vaping is based – in the simplest possible terms. The modern, more simplified Ohm’s law mathematical equation is:

I = V/R

Named after its initiator Georg Ohm, a German physicist, the law states that the current passing through a conductor from one point to another is directly proportional to the voltage supplied and inversely proportional to the resistance of the conductor. Put simply, the higher the voltage and the lower the resistance, the more current will go through, and vice versa.

Initially, people tried to use more powerful batteries to get higher voltage, but there are limits on how far you can push the amperage. So, the focus turned to reduce resistance in order to get more current, and resultantly thicker vapor. This brings us to sub-ohm vaping.

What is Sub-Ohm Vaping?

The resistance of a coil used in the atomizers 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 vapor. 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 vaporizer whose atomizer 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.

Is Sub-Ohm Vaping Safe?

The brutally honest answer is yes, and no. Depending on what type of tank you choose, there can be some risks involved but sub-ohm vaping isn’t categorically dangerous. For instance, the risk of batteries getting damaged from overheating is possible in a wide variety of other gadgets, let alone vape mods. But if you’re using substandard vaping gear, you will be inhaling more volumes of low-quality flavoring elements as compared to regular e-cigs, and might even inhale some unwanted particles of burnt metals. You can minimize these risks by choosing better products that are carefully made with your safety in mind.

Since there is a wide variety of coils, heating temperatures, wick materials and e-juices, only high-quality products made by skilled and experienced vendors can ensure your safety. In other words, the safest way is to use a regulated box mod instead of a mech mod. But if you want to try sub-ohming with a mechanical mod, make sure its generously vented so that the batteries can cool down during the operation.

Battery Considerations

The most important component in sub-ohm vaping, on which the reliability and robustness of the entire unit depends, is the batteries. Therefore, it’s extremely important to comprehend the capabilities as well as limitations of the batteries you’re using, especially their discharge rate. Some batteries have safe discharge rates under seven amperes, while others are safe at 30 amperes and even higher. As you lower the resistance of the coil, the required discharge rate for the battery goes up. To be on the safe side, the rule of thumb is to use batteries with the highest discharge rate with high resistance coils, however, this could cost you in terms of vapor volume and flavor. You have to find a sweet spot, and this is where experience and skills really count.

Advantages of Sub-Ohm Vaping

Advantages of Sub-Ohm VapingThere are three major benefits of sub-ohm vaping: more vapor, richer flavor, and warmer vapor. You’ll be blowing out the biggest clouds among your friends, shaming the other vapers who are vaping at higher resistance. The flavor 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 atomizer you use, there are three different options for sub-ohming.

  1. Rebuildable Dripping Atomizers
     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 Atomizers
     RTAs are an enhanced form of RDAs that don’t need to be dripped continuously, which surely was a sheer hassle. They are essentially clearomizers with a coil built inside them. The RTAs offer the highest volume vapors, plus very good flavor.
  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.

The Best E-Juices for Sub-Ohm Vaping

Mig Vapor High VG E-Liquid line for sub-ohm vaping

So, the million-dollar question is: do you really need any specific types of e-liquids for sub-ohm vaping? Well, the answer is absolutely yes, because at very high temperature, regular e-juices simply don’t stand a chance of producing decent flavor. In fact, even most so-called sub-ohm e-juices aren’t up to snuff. Just like making sub-ohm mods, making sub-ohm e-liquids is no joke. The issue with most products is that they don’t have the ideal VG/PG ratio, so at high wattages, the flavor simply doesn’t come through or even gives a burnt taste. In addition to unbalanced VG/PG ratios, using poor quality ingredients is the major reasons behind flavorless sub-ohm e-juices.

With seven unique flavors, Mig Vapor’s sub-ohm High VG Red Line juices have the perfect (i.e. 80/20) VG/PG ratio. On top of that, the juices are made in a clean, standardized facility in the United States, under vigilant monitoring and excellent quality control during the entire production process. So, when you’re using your sub-ohm vape mod, no matter you choose the Caribbean Freeze, Dark Angel, Vimanna or any other e-juice by Mig Vapor, you can rest assured that you’ll get the very best flavor. Although customized for sub-ohm vape mods, these e-juices go very well even for dripping and temperature control vaping. And in case if you want a more customized flavor, give the Vimanna e-juice bar a try to mix different flavors and make your unique flavor.

If you wondered why Mig Vapor’s High VG Red Line e-liquids are considered as the best sub-ohm e-juices, now you know our secret.
