When vaping using sub-ohm coils a substantial amount of vapor is produced compared to using coils above 1ohm on the same device. Typically sub-ohm vapers take lung hits meaning they inhale straight to their lungs increasing the vapor they can inhale each puff. Usually those vaping sub-ohm will use lower nicotine strengths (typically 6mg/ml and under) compare to those vaping above 1ohm because of the additional vapor produced and inhaled each pull.
How Does Sub-Ohm Vaping Work?
All 'mods' and e-cigarettes are electrical devices powered by a battery. Sub-ohm vaping utilizes the principles of Ohm’s and Joule’s laws of electricity. For our purposes this means, a non-variable voltage source like for instance the battery in a mechanical mod will increase the overall power output (wattage) of your device when you decrease the resistance (ohms) of your coils. It is absolutely crucial that sub-ohm vaping must be done safely. As you decrease your resistance you will increase the amperage your device uses to supply the current needed. This increases the strain on the battery and also increases heat that the battery and coils generate. For this reason you must ensure that you never exceed the amperage limit of your battery or it could fail causing possible fire or explosion.
