Great point about power outages.... I live in an old house, in an old neighborhood, and we have power outages like crazy. I never thought about it until I just read your post. Another reason why I am actually glad that I purchased a 510, then purchased a mega 510 battery, then purchased a 510 Riva. Because I had two starter kits, the 510 and the Riva 510, plus the additional mega 510 battery, I now have two chargers, and am able to constantly have 4 additional charged batteries...... Whenever one dies, I immediately put it on a charger so that I don't end up with a bunch of dead batteries. But this is a great reason for a car charger.
Thanks to the internet and this forum, I can't say there is really anything that I wish I knew before I started, but I can say that I am still trying to figure out my perfect nicotine level. For instance, today was a rough day, and I feel extremely stressed. Since I got home from work I've been vaping constant at 12 mg. and wonder whether its just not enough. I even picked up my one last virginia slims and lit it. I took two hits and put it out. I am amazed at how much like an ashtray it tasted!!!
