So, after I got my 3DS, I found out that it has this "charging cradle" where you plug it in on te back of the holder and place the 3DS on top. I think that the chargers should all be same instead of seperate chargers. Dizcus.
I like to use the charging cradle because it's just too much work to plug the cord into the back of the 3DS. With the charging cradle I jsut plop it on there and it charges.
