Mouth to lung vaping, and the use of a standard non sub ohm vape tank can be beneficial in a few ways. Firstly, because they use a lower power output combined with a higher resistance, these kits often have a longer battery life and use less liquid than that of a sub-ohm device. You won’t need to refill as often, which means carrying less liquid around with you on a day to day basis. Secondly, with a higher resistance coil, you’ll get a cooler vape, so if you’re a chain vaper, using one of these devices might prove more comfortable than that of the warmer vapour produced by a sub-ohm device. Another benefit that might prove useful is the discreteness of these devices. They produce less vapour than some of the larger devices, meaning you can get away with using it in more places!
