Sub ohm vaping: what you need to know (if you are a beginner vapor)
If you have decided to open this article, it means that you are also part of that group of curious people who would like to know more about sub ohm vaping, right?
Understanding how it works and knowing its advantages and disadvantages is essential to personalize your vaping experience and avoid making the usual mistakes.
You are wondering which ones, right?
In this article we have decided to collect all the information related to the sub ohm that every interested person should know.
Let’s start!
What is sub ohm vaping?
When electricity passes through a conductor (such as a coil), it encounters resistance, which is measured in ohms (Ω). In our case, if coils with a resistance of less than one ohm are used, we are talking about sub ohm vaping.
But what does it mean?
Imagine a country road and a four-lane highway. Many more cars can pass on the highway than on the road: this is what happens when we talk about sub ohms (therefore with a resistance of less than one ohm).
In this sense, you should know that there are some ways to increase the amount of vapor you get from your coil, and one of them is to increase the power of the battery: the more power you supply to the coil, the hotter it gets and the more vapor it collects can produce.
But there are limits to the amount of power that can be delivered to a resistor before it stops producing more steam and starts to overheat – you risk burning the cotton!
By combining a low resistance coil with increased airflow, more power can be enjoyed before excessive heat starts to be produced.
But how to do it?
Once the holes of the atomizer have been adjusted, the resistance of the coil will have to be lowered by using a thicker wire. If the same power is applied to two wires of the same length but different thicknesses, the thicker wire will heat up more slowly.
To reach a similar temperature at the same time with a low resistance coil, more power must be supplied.
By increasing the thickness of the thread, the contact surface of the bobbin with the wick is also increased. This allows you to vaporize a greater amount of e-liquid and therefore produce more vapor, resulting in the formation of those typical clouds of sub ohm vaping.

Sub Ohm Vaping and Ohm’s Law
If you have been dealing with vaper jargon for a while, chances are you have heard of Ohm’s Law.
Let’s see why it is so important for sub ohm vaping.
Today, most regulated box mods have built-in safety systems that prevent a coil with too low a resistance from being used for the battery, or worse, a coil that creates an electrical short.
A mechanical mod, on the other hand, does not have security systems. If you short a coil, there is nothing stopping you from completing the circuit when you press the power button. Therefore, if you are enthusiastic about building coils, you should be aware of the risk of a short circuit and pay attention to any contact between the coil and the base.
And this is where Ohm’s law comes into play: knowing it is essential for the proper functioning of the device, especially if it is mechanical. You will be able to calculate:
👉🏻 the value of the resistance of the coil (measured in ohms).
👉🏻 the amount of current flowing through the resistor (measured in amps).
👉🏻 the voltage applied to the coil based on the energy supplied by the battery (measured in Volts).
For these reasons, it is crucial to check the resistance of handmade coils with an ohmmeter before attempting to use them, and the application of Ohm’s law is more than essential.
However, if you use pre-built coils, there is no need to measure the resistance before using them because there is little to no chance of a short circuit.
Power Configurations and Benefits of Sub Ohm Vaping
Many vapers start with a low wattage or temperature and by combining that with a low resistance coil gradually build it up. However, it is better to do this practice only if you have experience or there is a risk of burning the coil.
A good starting point is the manufacturer’s instructions that come with your sub ohm tanks. In fact, many of these recommend the power and temperature range that can be achieved.
But at this point, you are wondering why vapers like sub ohm vaping, right?
Let’s just say that most people vape sub ohm because they want more vapor – for many it can be very satisfying to see huge clouds of vapor fill a room and dance in front of your eyes.
Also, it is possible to increase the throat hit although sub ohm vapers use high VG e-liquids to offset this increase.
Speaking of which, the larger atomizer holes are also required to manage VG e-liquids.
But that is not all.
Others find that sub ohm vaping gives better flavor.
Summarizing, we can say that the advantages of the sub ohm are:
✅ the increase in steam.
✅ improvement of taste.
✅ the production of a hotter vapor.
On the other hand, here are some disadvantages of the sub ohm:
❌ use more e-liquid.
❌ may require a change in inhalation technique.
❌ the battery drains much faster.
❌ Coil life is reduced.
