I would appreciate it very much if someone could explain the difference between the manual and automatic batteries.I have no idea why these pushbutton PTs/batteries are the preferred way to power ecigs. So far I notice the atty is not as hot and the juice is lasting longer. Also, I use that little hole on the atty to get a burst of vapor, but now that I have to push the button too, I can't figure out how to coordinate both things. I drip plus use a cart that I fill til its close to spilling. I tend to chain vape. Anyway, I am totally confused as to the difference so TIA to anyone who is willing to take the time to enlighten me.
