Traveling to Munich and Prague next month and picked up an adapter for my charger:
Amazon.com: USA US to EU Euro Plug Converter Travel Charger Adapter For Apple iBook/MacBook Compatible with Apple AC Adapters: A1036, M8482,661-2790, 661-2736, 661-3049, 661-3345,A1021,M8943LL/A: Electronics
Currently I use a plug similar to this from my ipod and it works perfectly and is much more portable than the cords that came with my M9. Does anyone have experience with this or something similar? Only thing I'm worried about is getting out there and finding out it doesn't work. We all know how long M9 batteries last and I'll only have two!
