Quick Overview

Teach any child or student the power of solar energy by building a USB solar charger! The finished charger is capable of charging small electronic devices.


Two rechargeable AA batteries, that when soldered to the solar panel, create a charging circuit that allows solar energy to be stored in the batteries. A Baltic Birch enclosure houses all of the internal parts and is held together by screws. We recommend painting or staining your enclosure to add a personal touch to it.

Note: Additional USB Cable not needed. It's an option in case you need one. When in doubt use the USB cable that came with your gadget.
