Can't charge my 3DS

[Nokturnal]

Hey guys, my charger isn't working here in Korea. We brought a converter and it works fine charging our phones and laptop, but not for the 3DS. Have you guys heard anything about this? Do I need to buy a separate ac adapter to be used here in Korea and Japan? If you guys find anything, let me know! If I can't find anything here, I might just wait for Japan and pickup an ac adapter there. Thanks guys!
