Solar power is continuously gaining momentum and popularity. There are now solar chargers designed to power cell-phones, cars, laptops, etc. The solar charger harnesses energy form the sun and stores the energy within its battery for later use. Typically, a solar charger can hold on to its charge for up to a year. The advantage to using a solar charger is that it eliminates all of those unnecessary, bulky chargers for every electronic device.

Solar powered cell phone chargers can be a better alternative to electrical cell phone chargers. You have to plug in your cell phone to a home outlet and then you have to wait a long time for your cell phone to be charged.
The charging of your cell phone takes electricity and the electricity costs money. It seems that you need to pay your mobile cell phone service provider for using your cell phone and you also have to pay the electric company for using your cell phone.

You are out of luck if you are outdoors and your cell phone battery dies. There are hardly any places that will let you plug in your cell phone in order to charge it. This is one of the reasons why a solar cell phone recharger is for you. You can charge your cell phone battery outdoors if your cell phone dies. It is true that you need sunlight in order to charge your cell phone, but most solar mobile phone chargers come with a storage device so that you can charge your cell phone even if there is no sunlight.
How Much Time do I Need to Full Charge?
General Rule to estimate total hours of direct sunlights to full charge: (Amperer per Hour of the Battery / Amperes per Hour of the Charger) + 10%
Assuming You have a 5 Watt / Hour Cell Phone Battery (like the one of Sony Ericsson Kurara, Nokia N900 or Razr V3) and a 2 Watt output solar Charger, You need first to convert Watt in Ampere: Ampere= Watt/Volts
It’s about 5/12 = 0.417 Amperes per Hours for the batery and 0.167 Amperes for the charger
To Calculate how much time You’ll need to charge the battery with a 2 Watt solar charger You’ll have:
1° Calculate the Ampere per hour of the charger: 2 Watts /12 Volts = 0.167 Amperes
2° Divide 0.417 amp hours (cell phone batery) / 0.167 ampers (solar charger) = 2.50 Hours of direct sunlight to full charge You cell phone Battery
3° Add 10%: 2.75 hours
Result: You’ll need an average of 3 hours of direct sunlight to full charge Your cell phone battery using a 2 Watt solar charger or 30 minutes if You have one of 18 Watt.
