We have a 3DS that we take everywhere. I'd like to build a portable charger using AA's. On the wall wart (AC adapter) it says the output is: DC 4.6V, 900mA.
My current parts list:
Case for project
3 AAs in series
Battery holders
3DS charging tip (I can get this)
wires/solder/glue
I don't think I need a voltage regulator since 3 AAs in series should be sufficient (please correct me if I'm wrong).
I'm a electronics newbie. Here's are my questions. Because a 900mA draw is alot, do I need a Current regulator? Does such a thing even exist? Once the current left in the batteries can't supply 900mA, what will happen? Will the 3DS continue to charge? Will it damage the 3DS?
Thanks in advance!
