Introduction to sub-ohm vaping
Sub-ohm vaping devices are very popular in the vaping community. Among many other things, they are popular because sub-ohm vaping devices are ideal for cloud chasers. In other words, the lower the resistance of the coil, the more power you can pump through it.
Back in old days, the only sub-ohm devices were all RDA atomizers or atomizers designed for dripping e-juices directly on the coils and wicking material.
That changed when Aspire designed the first sub-ohm tanks in the market. The Atlantis sub-ohm tanks with 0.5 ohm coil resistance were the first sub ohm tanks ever designed.
Sub-ohm vaping with high quality tanks is completely safe and enjoyable. Let’s cover some important topics for an amazing sub-ohm vaping experience!
What’s Sub-ohming or Sub-ohm vaping?
Firstly, to better understand sub-ohm vaping, we need to explain Ohm and Joule’s law.
Joule heating is basically the passage of an electric current through a conductor and producing heat in the process.
The Ohm’s law in this case, means that the lower the resistance of the coil the more power output we get.
Or, the bigger the current the more electricity is flowing. In other words, the electric current measured in A (amps) equals the voltage (V) divided by ohms (Ω). Below, the formula to calculate the electric current:
I = V/R
In conclusion, the lower the resistance (sub-ohm vaping) the more power we can get. For instance, the Atlantis sub ohm devices have a resistance lower than 1 ohm (Ω), hence the name “sub ohm”. This means that atomizers like the Atlantis are the most suitable ones for sub-ohm vaping.
Is sub ohm vaping dangerous?
Sub-ohm vaping isn’t dangerous. However, the problem is that some batteries aren’t intended for too high amps. If you are going to sub ohm, you need a battery that can generate enough amps. Moreover, there are some batteries with a screen that shows the device amperage, voltage and W. In other words, you need a battery capable of generating at least 40 W of output power.
For instance, Aspire has several mods with amazing power output generation. The Aspire SkyStar Mod generates up to 210 W or Aspire Archon (150 W) and Aspire Dynamo with a power output of 220 W! Or one of our latest devices, the Aspire Vrod kit (200 W).
All these mods are suitable for an amazing sub-ohm vaping experience!
What type of e-juices are suitable for sub-ohm vaping?
Sub-ohm vaping is ideal for cloud generation, which means you need a type of e-juice for sub-ohm vaping capable of producing big vaping clouds.
You need e-juices that contain more vegetable glycerin (VG) than propylene glycol (PG). Why? Because VG is thicker and generates denser and thicker vaping clouds.
There are many e-juices in the market with high concentrations of VG. Just surf the net and you’ll find lots of options for your sub-ohm vaping experience.
What about nicotine e-juices?
There are different nicotine concentrations of e-liquids ranging from 3 mg/ml, 6 mg/ml, 12 mg/ml, and 18 mg/ml and some e-juices containing concentrations of 24 mg/ml or even higher.
The production of vapor increases drastically with sub-ohm vaping. Hence, you need to choose a lower nicotine concentration.
Sub-ohm vaping: Conclusion
It’s not very complicated to understand sub-ohm vaping. To summarize, you need to think about:
1. The mod: You need a powerful one capable of generating enough power input. As previously mentioned, you need mods capable of generating at least 40 W.
2. Coil resistance: sub-ohm coil resistance. The lower the better. Basically, choose coils with a resistance lower than 0.5 Ω.
3. Right e-juice: you want e-juices capable of producing big vaping clouds. For that, you need more vegetable glycerin. It’s denser and produces thicker clouds. However, it’s also sweeter than PG.
