Hardware Anyone have a USB charger?

[Tyralyon]

So I just received my 3ds imported from Canada (I live in EU, Norway).

It was more or less an impulse buy as I will be working all Christmas, and since it's usually is a little slow during holiday season I will most likely have to kill off some time. Thought it was the perfect time to finally buy a 3ds.

The one thing I didn't think about was the fact that the charger is 110v.
Christmas is just around the corner and I will most likely not have any options of buying a 220v (will buy one from Amazon, but it won't get here in time).

Now I know you can get a USB cable for charging the 3ds, but I'm not sure if there are any resistors or anything involved?
Anyone here have a USB charger and a multimeter to check resistance? Or maybe even the knowledge of any other parts that may be in the cable?
I know you could do a straight from USB to the DS lite, but the DS lite was 5.2v and the 3ds is 4.6v...

I have a spare USB cable and the tools to solder, but don't want to bust my 3ds I got only a couple of hours ago.

HELP save my Christmas!!

The 3DS uses the exact same power as a DSi/XL. And the cable is just a cable. As long as you're connecting it to a computer/laptop, you should be fine. But stand-alone USB chargers? I wouldn't risk it unless you knew the exact details.

EDIT: And if i'm not mistaken, the amperage(?) or whatever is on the charger's sticker, along with the diagram. Mine says 4.6v, 900mA.

The output of a usb port is 5V 1A (iirc), and the input voltage of a DSi is about 4.6V (like ferofax says) so you should be fine.
And if you use a AC to usb adapter thing, be sure it's not some cheap-ass adapter, because those may screw things up.
I use a usb charger for my DSi as well btw.
