If your e-cigarette has an automatic battery, the vapor puffs the e-cigarette creates will unlikely be as large as those produced by an e-cigarette with an included manual battery because of the short retention between inhaling and vapor production.
With a manual battery, you can pre-heat the coil in the atomizer or cartomizer by clicking the button down before you inhale.
You can get nearly the same powerful effect with an automatic battery by taking one or two short puffs before taking the long puff that you want to inhale. These short puffs are called “primer puffs.”
When you get this long puff, you can get an absolute sensation of satisfaction and freedom. The smoking process has given the desired effect! Life could not be better!
