Im new here as well as to this kind of electronic cigarrettes, i was used to simple variable watts devices, so please pardon my ignorance, i read all about the device so i purchased a dna200 and applied sp5a. On device monitor it let's you choose amperage, does that stay? At the price point i was between 4 but having it all pre-set i chose Sdna75. Is it just me or battery is put backwards! Why? Its just confusing also i didn't know the wires would stay on my software! Pretty much just made it easy to use both my devices what are the changes for dna250? Other than bigger fuse 'reverse polarity protection' and more power. .. im coming from a 40w device, 200w is a lot, unless there is stuff not on youtube about chip upgrades?
