So I have a question on these safety bags/sleeves. Should I be charging any of my devices in there? Not only my Evod2, but also cell phones & such? I normally charge overnight, so is it safest to utilize these bags? I'll certainly make the investment to get more safety if that's what I need. I'm waiting on my innokin MPV2 to come in the mail, but now I think I may need to invest in some of these bags (1-2). Are some better than others?
