You need an iPhone case to protect your smartphone. Why not one that also recharges your phone via solar power, as in the SoL Solar Charging Case for the iPhone and iPod Touch?
This accessory from SoL Marketplace boasts an internal battery and integrated solar panel that extends the life of your iPhone and iPod Touch battery by 300 percent. According to the manufacturer, the case actually charges your portable electronic device three times faster than traditional wall chargers via “Rapid Charging Technology,” making it easier to charge gadgets on the go.
Included with the charger/case is a 5-pin mini USB cable, as well as three screen protectors designed for use as a mirror, to protect privacy and to deflect fingerprints, respectively. The case was designed to keep all touch screen features available while the device is charging and/or syncing to Apple iTunes or Microsoft Sync.
The SoL Solar Charging Case is currently available for the iPhone 2G/3G/3G, iPhone 4 and the iPod Touch 2G/3G; other Solar Charging Cases for other models are expected to become available soon.
