There is another problem to use USB battery (power bank) with Arduino and other dev-boards:

Most USB battery will disable output while charging, which means you can not use Solar panel with USB battery and Arduino, when Solar panel is charging the USB battery, USB battery will cut off the power to Arduino (or other boards).

I'v been thinking for a long time on how to solve this problem with a simple solution. Welcome to any suggestions.
