Build your own 1A+ 5V USB Charger with AA Batteries! by tristech

I couldn't find a usb charger that takes AA batteries with >1A power so I made one yesterday using a spare cable, some solder, and a couple 3d-printed parts I whipped up. I used mrbenbritton's AA battery holder design for speed of assembly and small design profile (http://www.thingiverse.com/thing:132966).
Use 4 batteries if they are 1.2V and 3 if they are 1.5V - and wire them in series (google it if you don't know how). This will work with pretty much any USB powered device... including gs3, gs4, google glass etc
