I'm about to go to Europe for about a month and I'm just wondering if the stock charger that comes with the lavatube will work over there. I mean work in a sense of, will I only need a wall adapter or do I actually need to go out and buy an 18650 charger with a Euro plug. I'm not sure if the charger self regulates power internally or not. If anyone has some idea, any help would be much appreciated.
