What's the one thing in the summer months that we are bathed in but can't make use of? And what's one thing a lot of us tend to want to charge a lot? If your answers were "solar power" and "smartphone" respectively, you are correct! Power outlets are not always available for our power-hungry electronic devices. Power-storing devices - external emergency batteries - are good ways of carrying around small bursts of energy with you, but if that runs out and you
still don't have access to a power outlet, what do you do?
What about a power-generating device? A solar panel, perhaps? This leather iPhone 4 case is just that; it has a 0.7W solar panel that, if left in th sun, feeds into a battery with a USB output for your favorite dock connector cable. Next to the USB out is a miniUSB in for charging the 1800mAh battery from more conventional sources, such as a computer or a power outlet, if you happen to find one. Also, just because this charger is also an iPhone 4 case doesn't mean it can only charge an iPhone; simply plug the relevant cable into the USB out port and connect it to your dumbphone, non-Apple smartphone, DS, PSP, or USB-powered flashlight. This battery, at full capacity, can charge iPhone 4s from 10% to 90% in 1.5 hours.
