Hi, I made a solar powered minty boost a while back (http://ladyada.net/make/solarlipo/). So I'm wondering, what's the difference between this: http://www.adafruit.com/products/259
and this: http://www.adafruit.com/products/390
Is there any difference in performance especially when it comes to solar?
Also, what's the difference between the USB LiIon/LiPoly charger - v1.2 (http://www.adafruit.com/products/259) and the v1.0?
Thanks in advance!
