This is an OEM Nintendo charger and is compatible with the DS, 3DS, 3DS XL and New 3DS XL.it outputs 4.6v, 900mA. It's a class 2 power supply and is made in China. It's ten bucks. There isn't much more to say about it except that it's reliable, OEM and works well, seems to charge up a system faster than cheaper options. I am not sure why anyone wouldn't just spend the money and get an OEM charger. I could see if it were 9 times as expensive than the competitive 3rd parties, but it'sten bucks.
