let us help you.
tell me what you did to turn it on again.
is the top box not turning on at all? or is it just not producing vapor? I'm assuming you have the subtank mini tank on there? what coils are you using? do you have a separate charger? and please take the batteries out and make sure they are not rusted and corroded.....
hey, I'm just trying to talk you off the ledge.
the sub tank mini is one of the most reliable vapes I've ever owned. I'm sure we can work it out.
