Really not sure if this is the right place and if it isn't I apologize. I was wondering, are there different types of USB wall socket things? I know I have to be careful when I get my setup in regards to charging the battery but I really don't want to rebuy anything I don't have to (would rather use that money on some ecig tech to tryout) but I currently have a USB wall plug thing that I use for my iPod, kobo, backup e-reader and blood glucose meter and if it would work for charging the ecig then that would be perfect for when I travel out of town (won't have to drag along the laptop just to charge my ecig).
