How to build a solar charger for the smartphone. You will need 1.8+ watt solar panel, battery clip adapter, universal charger with usb for the smartphone, and USB connector. Note: This solar charger is a very slow charger. It takes several hours to charge 10%. This is typical of all solar chargers. Great for camping and hiking where there is no access to electrical power, but still have access to cellular network and/or GPS signals. Tip: To speed up the charging power, turn off the smartphone or put it in sleep mode while charging. Next time I will hook up to a solar panel that is 5 watts, 350mA power to see how fast the charging will be. Thanks. Sipski
