===This works for GBA/DS (lite) Charger too!====> Do you want one USB charging for your DS? but don't want buy one? Don't worry! you can make one very easly! you can also use a PowerBank and charge it! Wow! What do you need: *Micro USB Charger (one cheapest will be better) *You charger (DSi, 3DS, DS Lite, DS fat, etc.) (if you have one NO ORIGINAL, will be better to no use your original charger, you select if use the original or one chinese, is the same!) *No solderess requried! (Scotch tape will be better for the cables) =========================================== Cut the Micro USB charger, and separate the cables, you should have like this: *4 Pins (Every Micro USB charger have different colors) Now cut every color, except Red (+) and black (-). Now do the same with your DS charger (DO NOT CUT NEAR OF THE CHARGER CENTER!!!) (> DSi Charger) All right, now make contact with USB pins, (+ and -) like this: And test it, if all works, congrats! you have USB charger! One final thing... use Scotch tape in the cables!!! (DO NOT PUT TOGETHER + AND - CABLES!!! ALWAYS SEPARATE IT!!!!) like this: Something important: USB AC Chargers always must be 5V MAX. NO MORE OR YOU WILL KILL YOUR 3DS! FAQ: Can i access to NAND with this? NO. How many time take to charge with USB? Same with AC Can i play while i charging via USB? Stupid question. Of course Can i use a PowerBank with my 3DS? Of course! Can i make more larger the cable? Of course, you choose the size! Can i plug it in my PC? Of course, but don't think you'll have access to NAND/SD SO I CAN TRAVEL WITH MY 3DS USB CHARGING AND POWERBANK?!?!?! Yeah!
