It has been almost three years since the original iPhone appeared in the hands of Steve Jobs, Time that has been necessary until Apple have decided to certify a solar charger as 'Works with iPhone', going on to sell in the Apple Store.
The charger has a built-in lithium battery with a capacity of 1320 mAh able to give us 30 minutes of conversation with a charge of two hours in full sun, something that is not bad for the device we are talking about.
It's available for $ 80 for the iPhone and $ 70 for the iPod touch., and before I forget I mention a good detail that they have had, and that is that they have included a meteorological application to make calculations on when and how long we will have to charge the iPhone.
