What is Sub-Ohm Vaping?

As more and more new products in the vape industry are geared toward Sub-Ohm vaping, many new and existing customers have the same question: What exactly is Sub-ohm Vaping?

What is Sub-ohm Vaping?

As the name implies, sub-ohm vaping deals with electricity, and this is not a subject that should be taken lightly. A traditional tank atomizer or cartomizer has a range of about 1.5 to 2.8 ohms. With sub-ohm vaping, atomizer coils or series of coils, with a total measurable resistance that is less than 1.0 ohm, are used. According to the laws of science (Ohm’s Law), a non-variable voltage source (like the battery in a Mechanical Mod) can produce more power (wattage) by lowering the resistance (ohms) of a circuit. So, using a lower ohm atomizer coil will result in bigger clouds, hotter vapor, and an intensified flavor.

Previously, to vape at sub ohm levels you would have to use a rebuildable atomizer to build your own coils. Now that sub-ohm tanks have arrived to market, consumers can now vape at sub ohm levels without having to resort to DIY. The basic concept behind sub-ohm tanks is to attempt to duplicate the effects of rebuildable dripping atomizer without all the hassle.

The Pros and Cons

Pros

  • Bigger clouds

Not everyone has the urge to blow massive plumes of vapor that are bigger and thicker than their neighbor’s, but if cloud chasing is something that you’re into, sub-ohm technology might be something worth trying.

  • Hotter vapor

The higher wattage creates a warmer, hotter vapor. This hotter vapor is why the RDA’s, RBA’s, and sub-ohm tanks have the airflow controls that cool the e-juice slightly so that it won’t burn the lips of the user. Many vapers prefer the hotter vapor because it simulates the effects of smoking traditional tobacco cigarettes.

  • More intense flavor

Steeping e-juices takes a great deal of time, in most cases. And leaving those tiny bottles lying around in closets and refrigerator shelves is very dangerous, especially for homes with small children. Because the e-liquids burn hotter, they also taste fuller, richer, and more intense. Many vapers who try sub-ohm methods often say that they will never again go back to the high-resistance, ceramic fiber clearomizers ever again.

Cons

  • Mouth-to-Lung Hitters

Sub-ohm vaping tends to give the user a massive lung hit of vapor. This extra “kick” is a feature than many sub-ohm enthusiasts simply love. Others in the vaping community call these people “Mouth-to-lungers.” Newbies to the technology might be a bit surprised at first.

  • Hard to Hide

The massive plumes of smoke and intense aroma produced from sub-ohm tanks draws a lot of extra attention from those around you. If you are trying to sneak a vape at the office, it’s going to be much tougher to hide. For the stealthier vaper, this might not be the best choice of tank.

  • Juice Monsters

It takes a lot of juice to make those massive clouds. For those just entering the world of sub-ohm vaping, don’t be surprised if you start going through e-juice like crazy. If you are vaping-on-a-budget, then this technique may not be your best choice. On a more positive note, vapers who use sub-ohm technology also tend to prefer lower nicotine levels in their e-liquids of perhaps 6mg or less, which can save you a little money. Some even opt for the zero-nic options. The bigger blast of vapor means a bigger blast of nicotine.

Methods of Sub-Ohm Vaping

  • RDA or Rebuildable Dripping Atomizer:

Before the release of the Aspire Atlantis and other sub-ohm tanks, RDA’s were the only method available to sub-ohm vape. RDA’s are also
called drippers, and we can use them with almost any Mechanical or Box Mod. Drippers are usually smaller than tank atomizers and include a deck for building the coil that we then attach by using a screwdriver. We then wick the coil with cotton. Users then drip a tiny amount of e-liquid on the coil and wick, re-dripping once every few puffs.

  • RBA, RTA, or Rebuildable Tank Atomizer:

This method is for people who want to avoid dripping completely but who still want to build their own coils. RBA’s are basically clearomizers that require the user to build the coil or coils inside. The great thing about this option is that users can custom design any coil imaginable to produce the precise vaping experience that they want. Not all RBA’s are for sub-ohm vaping though. So be careful. Some do not have the appropriate airflow controls and insulation required for sub ohm vaping. Without proper airflow an RTA can create a very hot vapor that may burn your lips.

  • Sub-Ohm Tanks:

This method is likely the perfect choice for first-timer sub-ohm vapers. They work very much like an RBA, but these use pre-made, disposable coils that can be purchased from the manufacturer. Some sub ohm tanks have optional RBA heads so users can choose to either build their own coils or use pre-built coil heads. This technology is the basis of the Kanger Subtank Mini , Aspire Atlantis V2 , the TFV4, among many others.

What are the ingredients of eJuice?

eJuice, the liquids that is used in our vapor devices, is made up of two main components.

Propylene Glycol - a moisture holder that helps retain flavoring

Vegetable Glycerin - a vegetable sugar that helps give eJuice shape

Propylene Glycol

Propylene Glycol is used in the flavor retention process in making eJuice. In the early days of eJuice, many companies were producing eJuice with at least 50% propylene glycol, resulting in slightly harsher hits and "watery" liquids. Many pharmaceutical companies began mass producing eliquids due to their access to Propylene Glycol, which is often used in many consumer products including foods and household items. There is a certain percentage of people (~10%) that have a Propylene Glycol allergy, which has led to the advancing of higher ratio Vegetable Glycerin eJuices

Vegetable Glycerin

Vegetable Glycerin is a vegetable sugar often used in cooking. This is an ingredient that can be found in niche grocery stores such as Trader Joes or Whole Foods. As vaping grows in popularity, and subohm tanks and cloud chasing becomes more of a popular market, high to 100% Vegetable Glycerin eJuice is making its way into the top liquids today. Many flavors are being produced with 70/30 or 80/20 (max VG) ratios. Due to the viscosity of vegetable glycerin, high VG eJuice helps users produce larger and denser vape clouds.

Flavoring

Outside of these two ingredients is the factor of flavoring, which is often the same extracts used in today's baked goods world. It's in this endless combination of flavoring types that individual and independent testing is warranted. Many companies have begun experimenting with different sweeteners and many cream flavorings have been known to test high in Diacetyl and Acetyl Propionyl, both being carcinogenic. Crystal Vapor pushes all the companies we work with to give full disclosure using independent lab testing and each company's ability to provide ISO (Lab Isolation) certification.

Nicotine

The final factor in eJuice is Nicotine, which is what gives eJuice and vaping the properties of smoking cessation. Nicotine is used to give users back control of their nicotine addiction. As Sub-Ohm Devices become more popular, the trend of lower to zero nicotine levels is growing stronger, with a success rate of smoking cessation higher than the patch. Nicotine is not a necessary ingredient in eJuice, and higher nicotine levels actually affect flavor negatively.
