I go through really unpredictable stuff with all my PTs. I have a bunch of chargers and a few PTs. All go through an extension cord to a wall plug. Some days they work right off the bat, others, like yesterday, I spent with various combinations and magically my 510 manual PT worked and now will work like a charm until I dare unplug it. I will not do this because the
vape from this particular PT is so sublime.
Still working on the voodoo.
