I am vaping a K100 and CHammer with Kanager Pro tank IIs. I am noticing quite a variation in vape quality and taste. I know there is a drop off in battery as it dies, but I am wondering if there are any tips in regulating that simply by how one vapes, as in puffing, less hitting the button, etc. I am also noticing that weather, time of day, and my own hydration seem to play a big roll. I wonder if anyone notices this and what has helped you to get good tasty vapes with mechanical mods.
