this is a link to the image of a charger I recently bought at eb games (my original had a fatal encounter with a washing machine) this was the only one I could find. since it is not endorsed ny nintendo and I can't find any reliable reviews of the product I was wondering if anyone knows anything about it and if it could harm my ds. PLEASe HeLp

it is the gamestop ac adapter for the ds and ds lite.
