Is Sub-Ohm vaping really that dangerous?

i've read a couple stories about super sub ohm multi coil builds like dual and quad .2 or .3 coils. It sounds like in most cases the issue comes down to a large amount of airflow to the coils and a wide drip tip which kind of allows really hot vapor and heated droplets of liquid to actually be inhaled.

I myself never go below 0.4 ohms and only build dual coils and even with my bigger RDA's that have tons of airflow, I have never had a problem.

The one thing that you need to worry about however is battery safety when sub ohm vaping. You need to be able to check the resistance of your coils using an ohm meter (you can get one specifically for RDAs), have batteries that can handle the coil you build, and a good charger for the batteries.

One tool you can use to see if your batteries can handle the build you set up is this Ohms Law calculator
Ohm's Law Calculators and Formulas

Basically, if your batteries can't handle the coil you build, they can go into runaway mode and catch fire.

 

The sad part is sub-ohming is becoming so talked about and so commonplace that everyone wants to do it. They don't read up on safety or the correct way to do things. They buy some Kanthal, a dripper, and a cotton ball and go to town. THIS is where accidents happen. Burns, explosions, fires, seriously. If you MUST sub-ohm, PLEASE do your homework.

Personally, I'm fine at .08 or higher, but that's all personal preference.

One more thing, if you're going to sub-ohm, do NOT subohm at your normal nic level. Step it down a whole bunch of notches. You'll thank me later.

 

Could someone explain what Sub-ohm vaping is please? Thank you

 

Basically, what you want to remember is that your battery has to be stronger than the atomizer. Wherever you go to buy yours, ask the sales staff about the ratio. If they don't have a clue as to what you're talking about, find another store.
