My professional experience.
I attended the U.S. Army Signal School for the study of Electronics. I specialized in the MOS 31S10 Field General ComSec Repairer and 31S10x9 Depot Certification. This required 22 months of hands on electronic training. I attended electronics courses in high school and I have enough Upper Division units for my Bachelors of Science in Electronic Engineering. I worked in the Military on electronics for 11 years. I've since migrated to computers, it pays better.
Sub Ohm vaping presents a unique set of obstacles.
You will have to make your own coils or find a place that can make them for you in your commute range. This applies to "micro coils" as well.
You will need to test your coils to verify they have resistance.
This also applies to micro coils too.
You will be taking an additional risk in using a sub ohm coil, if you use a mechanical MOD.
MOST variable voltage(VV) or variable wattage(VW) battery MODs have electronics circuits that shut off the device when conditions exceed their limits. Too much Voltage from the battery? The MOD shuts off. Too Many Amps at the switch? The MOD shuts off. Too low a resistance from the coil? The MOD shuts off. Some even have thermal sensors. Too much heat? The MOD shuts off.
When you use a sub ohm coil, the typical device used is a mechanical MOD. Mechanical devices are merely a switch and a battery tube. Mechanical devices will NOT shut off if there are problems. They will continue until the switch is released or the battery fails completely. This can lead to battery thermal runaway, which may in extreme cases, result in an explosion of the battery. A battery CAN end up in a thermal runaway condition even in a VV or VW MOD, but the circuitry will typically STOP the MOD long before this can begin to take place.
Use protected batteries, or a safety device such as a kick or a safety fuse, or both anytime you use a mechanical MOD, sub ohm or not.
Even long term experienced sub ohm users need to be vigilant and pay very close attention. A friend set his mechanical on a shelf and the button was depressed by the weight of the mechanical, it melted the battery SIGNIFICANTLY in less than 2 minutes. It burned his hand when he picked it up. He had to replace the mechanical and the battery. This friend: Owns a store; has been vaping for years; builds sub ohm coils professionally; has been using sub ohm coils for years. This happened in front of me, and it can happen to YOU too.
Grimm Green shares an interesting story about his Silver Bullet, and a melt down in one of his videos. Fortunately his Silver Bullet's spring melted, preventing any major issue. He had to replace the spring and toss a battery.
Any rebuild-able atomizer (RBA) or rebuild-able dripping atomizer (RBDA) can be used on a VV/VW standard MOD, with a longer coil, that is 1.5 Ohms or higher, with very similar results to a sub ohm coil on a mechanical MOD. Grimm Green has a very detailed video about making micro coils. There are other sources as well.
One of the huge advantages to sub ohm is the duration and speed of the coil heating. This can also give you a longer battery life. Increased vapor production and increased flavor. Most of those advantages can be accomplished with a micro coil, as well. Is it really worth taking a significant risk, to use that sub ohm coil on a mechanical? I have done it, but I believe the micro coil is a much safer alternative.
I sincerely hope you enjoy vaping, no matter what way you choose to vape, and that it never causes a problem for you.
