Sub-Ohm and Plus-Ohm Vaping

With sub-ohm or regular ohm vaping, it all comes down to the kind of tank you're using – or more specifically, the actual coil in the tank. Each coil comes with its own ohm rating, usually written on the side. Ohm is a unit of electrical resistance, and to put it simply if the coil is below 1 ohm it is sub ohm and if it's above 1 ohm it is plus ohm. But how does this relate to vaping? Well, this simple difference has dramatically different effects. Let's look at each in turn.

Plus-Ohm Vaping
If a coil has high resistance, eg. if it's 1.8ohms, this means it is resisting more power from the battery and will take longer to heat up and reach a certain point. In turn, this means your e-juice is vaporized at a lower rate compared to a sub ohm coil. This means batteries for plus-ohm vaping don't have to give out as much power, and can be small and subtle. Regular-ohm vaping is most suited for a style of inhale known as Mouth To Lung (MTL).

Sub-Ohm Vaping
Sub-ohm coils have lower resistance meaning they heat e-liquid quicker and more powerfully. This makes for a dramatically different sensation from a regular ohm vape, with much more vapor production and a warmer and more substantial mouthfeel. This is a relatively Plus-Ohm vs. Sub-Ohm vaping new form of vaping and only became widespread over the past couple of years as vape technology became more advanced. Batteries need to be bigger to be able to produce more power meaning safety is a more pressing issue when using this kind of set-up. Sub-ohm vaping lends itself to the Direct Lung Inhale (DLI) style of draw.
