What Is Sub-Ohm Vaping?

Sub-ohm vaping refers to an e-cig user using coils (atomizer heads) in their vape tank that have a resistance of less than 1 ohm. Sub-ohm vapers experience greater flavour and vapour production due to an increased power output of the e-cig or mechanical vape mod, ensuring smooth mouth-to-lung vaping. Sub-ohm vaping is the key to big clouds, or cloud-chasing.

By using sub-ohm coils, you will experience an huge vapour, intense flavour and a warmer vapour than usual. Sub-ohm tanks and sub-ohm coils are just as easy to replace and change as regulars, and you may want to try a variety of vaping setups so you find your perfect vape. High VG liquid is especially intended for sub-ohm vaping as it is thick, smooth and full of flavour, which is needed for sub-ohm setups as the vaper inhales an increased amount of vapour.

Sub-ohm vape tanks & atomizers that you may be familiar with include the Smok TFV8 series, the Aspire Cleito range of vape tanks and other favourites of the vaping community.

How Does Sub-Ohm Vaping Work?

Regulated mods, e-cigs and mechanical mods are powered by battery and sub-ohm vaping makes use of the principles of Ohm's and Joule's laws of electricity. With e-cigarettes, the battery in the mechanical mods, a non-variable voltage source, increases the overall wattage as the use decreases resistance with coils.

As coil resistance lowers, the amperage provided by the battery to supply the current to the mod will increase, which will place further strain on the battery and can make the battery and coil get very hot. It's very important that sub-ohm vapers properly research their devices and understand how to use their device. Users should not exceed the amperage limit of the e-cig battery.

Choosing The Right Battery

Your choice of battery is crucial when vaping using a sub-ohm setup. It is very important that you understand how to choose the right battery and use it safely. Like all e-cigarette batteries, your sub-ohm e-cig battery should never be exposed to water, heat or cold. If the battery wrapper is damaged or the shell is dented or damaged, you should never use the battery. In addition, you should always obtain your sub-ohm vape battery for a reputable or well established e-cig store to ensure safety.

To work out the current that your vaping setup will require, simply divide your battery voltage by the coil resistance. You should always check your resistance before you vape to ensure that you do not exceed your battery amperage limit.

The standard battery of choice for sub-ohm users is often an unprotected IMR or a hybrid lithium battery, which pose fewer risks with their safer construction should the battery be damaged. For the best and safest sub-ohm experience, many vapers choose batteries with the highest continuous amperage limits.

E-Liquids & Nicotine With Sub-Ohm Vaping

As sub-ohm vape setups produce masses of flavour and vapour, sub-ohm users normally elect for e-liquid higher in VG content rather than PG. PG provides a stronger throat hit, whereas VG creates larger clouds and denser vapour.

Sub-ohm vapers inhale vapour straight to the lungs, so it's important the nicotine hit isn't too severe. Using sub-ohm coils, you shouldn't be looking for e-liquid greater than 6mg nicotine, as vapers using sub-ohm coils inhale increased vapour and flavour.
