Anyone know how auto batteries work? Does the suction force somehow turn on the battery? I also tend to associate auto battery with the cigarette like devices that I've tried years ago which didn't do anything for me. They were unreliable.
I've been using the Ego Twist and although you have to press a button, it offered reliability.
So has auto batteries improved on the reliability department?
Are manual batteries going to be obsolete in the future?
thanks
