ok ok lets evaluate this then...
open box, unscrew screw from back side, put in a vtc4 positive side to positive post, and negative side to negative post, screw in kayfun, says short, screw in aerotank, fire vape and repeat, set down unit, ????, smoke from unit.
you're right, i totally made an error, didn't I?
Is it possible that it was vapor escaping from your tank and not smoke just wondering
