What is sub-ohm vaping?

To put it simply, it means vaping on a device that comes with a resistance level of less than 1.0ohm. If higher than this, then you should have a regular resistance for vaping. As the coil resistance gets less, it allows a higher current to flow through, which makes the coil heat up quicker, thus resulting in the e-liquid being vaporized super fast, and finally bringing you a huge vapor cloud and great flavor.
