Sounds faulty to me. You could try a different charger I guess, but unless there is some strange procedure (usually there isn't) those pen type
batteries which is what I think yours is? (IDK quite know, sorry) there is no special "thing' you do besides plugging it in.
Was it bad when you got it? Have you watched a youtube video or two (if there is one)? Do you have a vapes store near you to test it for you?
Sorry to not be of more help, I'm sure someone more knowledgeable may come along. You did use five clicks to turn it on? IDK. It may be faulty or it may be you, but I am sort of leaning toward faulty since it is not actually charging.
