No, they use different sized plugs, so they're incompatable with each other
No, the DSi charger is different than the DS lite charger
No, the DSi uses a different charge to the DS lite.
you cant use the 3DS charger for the DS/DS Lite, but you can use the 3DS charger for the DSi and the same with the DSi charger, you can use it for the 3DS.
No, the DSi and the DSi XL both have different plug-in holes in the side from the DS Lite, and so they cannot use the same charger. You figure that out after you sleepily try to use the wrong charger a few times.
On the original Nintendo DS yes they use the same charger, but on the Nintendo DS lite and Nintendo DSi that is not the case.
No, though it can use a DSi or DSi XL's charger.
When you bought the DSi a charger, it should of come with one. If not you can easily buy a DSi charger from any gaming stores. Also a Nintendo DSi XL charger as well as the Nintendo 3DS (and XL) charger will work since they are the same.
No. The black charger for the DS and the dark grey charger for the DS lite are incompatible with the 3DS. You need the pale grey charger that has been released with all of Nintendo's handhelds from the DSi onwards.
It would be pointless to keep the charger unless you have a second DS Lite with which to use it. The DS series have different types of chargers for each individual DS, so a DS Lite charger would not work with a DSi.
The 3DS uses the exact same charge cable that is used on the DSi and DSi XL (Part #WPA-002). You can charge the unit either with the cable alone or on the cradle, which the cable plugs into.
Yes. The DSi, DSiXL, 3DS, and 3DS XL all have the same charger.
No. A DSI cant use a 3DS charger.
