Solar Cell Phone Chargers
Since we all walk many hours in the sun each day, does anyone have knowledge of a functional solar charger for phones or cameras?
 

For which type of mobiles you asking about?

Use 3W solar panel to 5v voltage regulator (LM7805 preferable).

Connect the output 5v to the mobile charger connectors.

This circuit works well for old mobiles (Not usb type), which is having 2 wires(inside).

Now all the mobile chargers coming with USB 4-wires.
I don't about this type of chargers.
 

There is a couple of ways.
A solar panel connected to the charging port of your phone; or a solar power 'bank' = solar panel + built-in storage battery that connects to your phone charging port.

The 'candy store' has maaaany choices :
