12 Volt DC adaptor for Europe? Where can I find adaptors that will work in
Where can I find adaptors that will work in Norway and Germany?
Answers: Most power "bricks" will work on both 110V and 220V.
(Just check the sticky label. If it says Input 100V-220V AC, you can use them as is)
If you enjoy already the adaptor, say 110V AC to 12V DC, consequently you can buy a 220V AC to 110V AC adaptor where you can connect the 12V power supply. Most travel-related stores market them (even in European airports).
If you don't own anything, you can buy adaptors in electronic stores at the country you call in.
