HELP PLEASE! I am returning to vaping after a year. I have a provari, 2 provari minis and an OMG Box. I recharged my battaries and while the light would turn on,there was absolutely no vaping power in any of these 4. I went out and bought all new batteries, figuring the battaries were old and just had insufficient power. I have recharged them. Same problem. Can anyone tell me what I am doing wrong? All 4 units? Really? I am desperate and would appreciate whatever help you can give me.
