From the research I have done, it requires an org cable, an USB y-cable for hooking up an external power, and a from with org support. The two cables can be found on Amazon for 2-5$. You could use any USB charger or for portability... get one of the battery packs with USB output. Portable, but it is a lot to carry around.
You can also use a powered USB hub in place of the y cable.
