What is sub-ohm vaping?

So, what is this sub-ohm thing?

Sub-ohm vaping, simply put, is vaping on a device with coils that have a resistance of less than one ohm.

Sub-ohming used to be some obscure thing for expert-vapers only, using mechanical mods, 18650 batteries, rebuildable tanks and Ohm/Volt-meters. However, with new devices getting released every day, the term ‘sub-ohm vaping’ seems to rise in popularity. Because, let’s face it. Who doesn’t want to turn their living room into a fog bank in only a matter of seconds?

In the past, sub-ohm vaping required building your own coils and measuring their resistance before usage. The equipment required to build a coil alone would cost the amount of a regular e-cig, and then you’d still have to buy a mod, batteries and a tank.

Since then, a lot has changed. Regulated mods were introduced to the vaping community, prices of sub-ohm thanks have dropped drastically, and pre-wired sub-ohm coils are widely available on the market.

 


Ok, but why would I want that?

If done right, sub-ohm vaping produces more vapor and thus: bigger clouds. This is caused by the fact that a sub-ohm coil has a lower resistance (hence the term ‘sub’-ohm. Because of this, the e-cigarette’s battery generates a higher wattage, causing the coil to become hotter.

The resistance of a heating coil is defined in ohms. This expresses the amount of current that the coil restricts If the voltage of the battery is the same, lowering the resistance of the coil increases the amount of wattage generated.

Using the right setup, sub-ohm vaping generates a lot more vapor and flavor than a standard e-cigarette would. It also drastically increases the amount of liquid consumed. This causes each puff to contain more nicotine. This is why most sub-ohm vapers use lower nicotine strenghts than they would use on an above-ohm coil.

Typically, a sub-ohm vaper takes direct-lung hits, because this increases the amount of vapor they can inhale in one puff. If you are a mouth-to-lung vaper, sub-ohming might not be for you.

Caution: as you decrease the resistance of your coil, you will increase the amperage used to supply the current needed. This increases the strain on the battery, and with that, increases the heat that the battery and coils generate. For this reason, please ensure that you never exceed the amperage limit of your battery. Otherwise, your battery could fail, possibly causing fire or explosion.
