Simply draw on it like you would a cigarette and the battery powers on without having to 
hold a button! This is a great advantage for those who have difficulty locating the button on standard batteries.
There is an automatic 10 second cut off, meaning after 10 seconds of continually drawing 
on the battery it will turn off momentarily, in order to allow you to get ready for round 2!
