It is important to know what an Ohm is before you try out sub-Ohm vaping. An Ohm is the standard unit used for measuring the resistance of a coil. The symbol used for an Ohm is; Ω. Most mouths to lung tanks have a resistance of 1.2Ω to 2.0Ω. A sub-Ohm occurs when the resistance of a coil is below 1 Ohm.
If the resistance of a coil reduces and constant voltage passes through it, the current passing through it increases resulting to heating and production of vapour. Thick wires have little resistance to current flow since they have a big surface area.
Sub-Ohm Vaping is when you use a vaporiser whose coil has a resistance of below 1 Ohm. You can inhale the vapour in two ways, putting the smoke in your mouth briefly before inhaling or inhaling directly to your lung. This might sound like a simple thing, but it is somewhat complicated. So, let’s talk about it more.
Sub-Ohm Vaping involves three things:
Sub tanks usually have high airflow for two reasons:
Sub tanks use unique kind of batteries. Sub tanks generate more heat than regular tanks, drawing a lot of power from the batteries. So you need sub ready batteries. The batteries come if various shapes and you should check while purchasing to ensure you buy the right type.
The primary ingredients in the e-liquid are PG and VG. PG produces a scratchy feeling at the back of the throat. People looking for a cigarette substitute usually enjoy this sensation. VG provides a smooth taste and emits more clouds. Most people use E-liquids with high VG quantities to produce big clouds while inhaling little nicotine.
Well, the answer to this question can be no, and yes. Sub Ohm vaping is not regarded as dangerous but depending on the sub tank you use, there can be some risks. For example, the batteries you use can be damaged just like in any other gadget.
If you use low quality vaping gear, you will most likely inhale substandard flavoured vapour compared to the usual e-cigs. There is also a risk of inhaling burn metal vapour. In order to minimize such risks, ensure you buy high quality vaping gears that are designed with your safety in mind.
