It is also possible to charge the Nintendo 3DS without the charging cradle. Just connect the DC plug of the Nintendo 3DS AC adapter directly to the AC adapter connector. You can also charge your Nintendo 3DS using the Power Supply for a Nintendo DSi or Nintendo DSi XL.

Charge up your Nintendo DSi, DSi XL or Nintendo 3DS & 3DS XL console from your USB power point, PC, Playstation or any other source with a USB port. Plug one end into your PC USB port and the other end into your Nintendo DSi, DSI XL or Nintendo 3DS and 3 hours later its fully charged.

Nintendo 3DS, 2DS and DSi Chargers Are The Same From the Nintendo DSi onwards, the charger shape is slimmer and actually the same across all of Nintendo's newer models. This means a Nintendo DS charger will also work with the Nintendo DSi, Nintendo DSi XL, Nintendo 3DS, Nintendo 2DS & Nintendo 3DS XL.

As long as your Apple charger is 110-240v, like a travel charger, then yes it will work. Keep in mind it may be too much for the 3DS, and it's advisable that, depending on the 3DS USB cable's quality, you may have to charge while the system is off. Playing while charging with an unauthorized charger can lead to damage.
