There are two tips listed for Nintendo DS, tip 54002 and 54930. Both indicate in the header they are for DSI but in the description, the 54930 indicate they are for Nintendo DS. I have two year old Nintendo DS Lite - not the new Nintendo XL. Which tip should I purchase? Thank you for any information you can provide.

The Nintendo DS tips are not compatible with the Nintendo DS Lite acording to online information.  The DS Lite tip looks like a Mini USB tip 54907 or 54930. However,  I advise you to contact Nintendo to confirm as I cannot guarantee either tip will work.
