Get a USB cable for my 2DS?

Doesn’t look like Nintendo makes a USB cable. Some of the third party ones on Amazon break. You can get one for two bucks on eBay. If I had a USB cable for it, I could charge it using my external battery. Not using that battery for anything else, probably enough capacity to charge my phone and the 2DS.

Could also charge it using somebody phone charger, assuming it has a USB port. Just unplug the cable for the phone and plug the 3DS/2DS cable in. 2DS uses the same charger as the 3DS.

Cool battery fits in my case, might fit better then the AC adapter.
