What is sub-ohm vaping?
When you push electricity through a conductor (such as a coil) it meets resistance.
This resistance is measured in Ohms (Ω).
When you use coils with a resistance of less than 1 ohm, you are sub-ohm vaping.
Today, sub-ohm resistances are common in off-the-shelf tanks and pre-built coils, but it hasn’t always been this way.
Only a few years ago, safe & sub ohm capable batteries like the Smok Morph 2 were not readily available. The only way to experience sub-ohm vaping was by building coils and using them with a mechanical mod.
But sub-ohm vaping has matured…
Mechanical mods are still available, but battery and chip technology has moved on a great deal. The evolution of hardware has brought safe sub-ohm vaping to the masses.
How does sub-ohm vaping work?
There are two ways to increase the amount of vapour you get from your coil. One is to increase the power of your battery. The more power you provide to your coil, the hotter it gets and the more vapour you can produce.
But there are limits to the amount of power you can put through a coil before it stops producing more vapour and starts producing excessive heat.
Excessive heat can cause the vapour to get uncomfortably hot or even burn your wick. Burnt cotton doesn’t taste too good!
By combining a lower resistance coil with more airflow you can use more power before you start creating excessive heat.
