Solar Mobile Charger is a separate device that uses a small solar panel to absorb light and then transfer to the phone. This process still forces customers to carry around another device along with their cell phones". Solar cell phone chargers use solar panels to charge cell phone batteries. They are an alternative to conventional electrical cell phone chargers[1] and in some cases can be plugged into an electrical outlet. There are also public solar chargers for mobile phones which can be installed permanently in public places such as streets, park and squares.
