Picture of Usb adapter for Nintendo DS
How to create an usb power adapter for your nintendo ds out of an usb cable & your nintendo ds charger.

Step 1: Analyzing

I noticed that my ndsl charger supplies almost 6v, so i decided to use a normal usb port to charge my ds, also because my pc can supply 5.1 volts that are perfect for charging it (and also because it is always turned on during the day).

1) Take apart your nds charger.
2) Look inside it & search for the power cord.
3) Using your tester(V), check & write down the position of the tiny cables inside the cord.
4) Close your charger, plug it on an outlet & write down the + & the - on the connector.

really good work!!! but i think it's a little complicate than buy a new cable for DS or a charger for DS!!

hello, i have a friend who supposedly used to have access to a cable that was from the ds charger to something that would connect to a projector (i would assume that it was to VGA) and it would display everything on the screen on to the projector, but it would drain the ds battery life, if any one knows about it plz tell me more, please note it wasn't me who was able to use this cable. and that i have never been able to see it in person. if anyone knows this instructable could help be used to fabricate the cable.

nice Instructable. although it would be far simpler to just use a: USB A to 5-pin USB mini-B Cable (I'm certain it's the mini b). it just takes a little wiggling to get it in right but it'll work at least for the ds lite

No, different connectors. It could damage the port.

i've done this for months with no sign of damage

hmm, for some reason i am drawn to this... good work! i would try but i only have one charger, if i mess this up i can't use my DS.
I got a used DS charger off of Amazon.com for 50cents. (Plus 5 dollars s&h)

LOL. Shipping more expensive than product.

I have only a charger too... just pay attention and don't be in a hurry.
it works fine UNTIL IT BLOWS YOUR DS BATTERY!!!!!!!!!!!!!!
It's not gonna. The DS has internal circuitry to prevent that. The adapter just provides +5 Volts. USB power just happens to be 5 Volts, so this will work fine (so long as you don't screw up).

What is the purpose of this? I mean will I be able to download files from my computer to my ds with out a portable usb card? I would like to know before I tear up my cables...lol
lol, i just have a regular ds, and only 1 charger, hehe

This is exactly what I did when my AC adapter died on me. I used a USB cable from the dollar tree, spliced the appropriate wires and bam. Easy charge for $1. I later bought a commercial-made one which was pretty much identical except for the quality. The beauty of many electronics these days is that they are all 5ish volts to charge with no modifications, which is the same output of a standard USB port.
what exactly would you use that for?
m6233555m (author)  childthesecond7 years ago
I thought that would be an excellent idea to charge the ds with my pc, also because my pc is turned on most of the time...

I done the same project (before reading your guide). That is very close to what I did. Only difference is I did not open up my charger. Instead I used the label in the back of the adapter for a guide what wire is what polarity.
Nice work. I look forward to trying this with my charger.

Heh, I tried to build one of these a while ago, but I got the polarity wrong and ended up frying the usb power chip on my mobo, and if 1 chip dont work, none do. So a 20c chip kept my 1200$ computer from working. Just great. Check your polarities if you try this!
