No, the DSi XL has its own charger.
No, the 3DS charger is different than the DS charger. However, the DSi charger (as well as the DSi XL) is the same as the 3DS and 3DS XL
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.
You can't, the DSi XL needs the pale grey DSi/3DS charger. It can't be charged using the black DS charger or the dark grey DS Lite charger.
Yes, the DSi charger is the same as the DSi XL.
Yes, DS games do work in a DSi XL. The DSi XL is part of the DS line, so DS games are meant to work with it.
It's fairly obvious - unless you are trying to use an old DS charger with a DSi. All four models of the DS use completely different chargers to each other. If you have a DSi, you need a DSi charger. A DSi XL will need an XL charger too, etc.
No. The charger for the original DS is only compatible with the DS and Game Boy Advance. The charger that the DSi XL uses is the same as the one used by the DSi and 3DS.
No, though it can use a DSi or DSi XL's charger.
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.
yes a dsi charger fits a dsi XL and a dsi XL fits the dsi
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.
All of the games that work for any DS will work for DSI XL.
