Solar Charger and Adjustable Power Supply

In this instructable I am going to show you how to build a Solar Charger in a very simple way, so that it will be easy and affordable for anyone to build its own one. We are going to use solar panels as our source of energy, to be able to use this device anywhere. We will use some Li-ion batteries to store the solar energy when it is available, so that we can use it at every time, not only when it is sunny.”
