I'm about ready to make my first purchase,and will go with an eGo.The kit contains all the normal stuff,but the one question I have that I haven't asked is,what are they talking about when they say the kit includes One x USB Charger and One x Charger Adaptor?I think I understand the USB charger,they are for plugging into the computer to charge.But what is the charger adaptor?Am I getting a charger that I can't plug into a wall socket?
