USB gadget solar charger

Hi,

A few days ago i built a solar charger for usb gadget with some of parts from sparkfun and adafruit industries. Did you plan to make a kit with DC-DC converter, battery and solar charger ? It could be very interesting for all our electronics gadgets :wink:

Hi, Iā€™m interested in more details:

What voltage and current does your charger produce?

Where did you get the solar cell array from?

Do you have a schematic for the charger?

Thanks in advance

Hi,

Iā€™m using sparkfun LiPoly Charger - Single Cell 3.7-7V Input to charge a lipo battery with a 6v solar panel. I convert 3.7v from the battery to 5v for usb output with a mintyboost MintyBoost Kit. It should be better if we have the lipo charger on mintyboost PCB.

Cell array is from adafruit industries.
