Solar energy for e-books, iPad, iPhone, other mobile phones and USB devices

Solar Panel Cover For The Kindle E-reader, by Energy Matters, 9 Jan 12 Using solar energy to provide power for hand-held devices has huge potential and while solar panels embedded in mobile phones mightn’t be much chop (yet) in terms of performance; it seems a new solar cover for the Kindle e-reader delivers.

The SolarKindle, weighing just 215 grams, incorporates a flexible, lightweight triple junction amorphous solar panel and is able to provide some level of charging even in the shade.  A one hour charge in direct sunlight can provide almost three days worth of reading time according to the company that created the device, SolarFocus Technology.

After fully charging the Kindle, the solar panel automatically switches to charge the SolarKindle’s 1500mA reserve battery. A fully charged reserve battery requires around eight hours of direct sunlight and provides up to 80% of backup power to the Kindle.

……. sticking your SolarKindle enshrouded e-reader out in the sun on a 40 degree day for extended periods may be unwise.

The SolarKindle also incorporates an 800 lux LED reading lamp. If the reserve battery is used for lighting alone, it can power the light for up to 50 hours. An LED indicator incorporated in the SolarKindle shows battery power level and status of charging and discharging.

The SolarKindle can be purchased online for around AUD $80, plus delivery.
SolarFocus was named an International CES Innovations 2012 Design and Engineering Awards Honoree for its SolarKindle Lighted Cover. The company says it holds several solar technology patents with their products used in extreme environments such as the Himalayas and the North Pole.

SolarFocus also manufactures a folding solar charger for the iPad, iPhone, other mobile phones and USB devices called the SolarMio Pro. While certainly not as compact as the embedded solar panel Nokia recently trialed, the 5 watt SolarMio Pro watt system can provide 6 hours of talk time on the iPhone 3Gs with just an hour of solar charging..   http://www.energymatters.com.au/index.php?main_page=news_article&article_id=1972
