Hello everyone! I just recently imported a Japanese DSi after my American DSi broke and I was wondering if it was safe to use one of these on a US outlet.. It's one of those 3DS/3DS XL/DSi XL/DSi charger replacements sold in Japan (I lost the original charger that came the DSi) What I have heard was mixed, some claim that these chargers accept 100V (The voltage standard in Japan) and 120V (The standard in the US) and work just fine on American outlets however some are saying to get a step-down voltage converter. If anyone has a Japanese 3DS or DSi can you please specify the ratings on the chargers? Thanks!
