Can you charge it from a battery pack? I seem to remember reading before launch that might not have been possible
Yup. I have a 20,000mah USB battery and it charges it fine.
For games like Zelda, you'll need one that pushes a higher current through 2.1amp rather than 1amp otherwise it can't charge quick enough for you to use it at the same time.
