Solar Powered Cell Phone Charger |
| The simple circuit below
regulates the voltage from a 6v solar panel to a fixed +5v. That voltage can be
fed to any cell phone or USB connected portable device, to charge its battery.
The circuit uses a Reg113-5 voltage regulator from Texas Instruments. The tiny device
can handle up to 400ma of charging current. I would suggest using a solar panel
rated for less than 2 watts and one which contains 12 solar cells. One such
panel is shown below. |
