If you’re thinking of picking up a case for your iPhones, better it be the Smart Cover case that has a solar panel at the back, which can give you added talk time hours.

All you have to do is slide the case at the back of the iPhone or iPod and it will automatically charge your gadgets once it catches some rays from the sun. If you can leave it under the sun for an enough amount of time, you will be able to charge it fully and use it for 390 hours of standby time or a total of 9.5 hours of actual talk time.

Priced at $139.99, you can even use the Smart Cover to charge your laptops by simply pulling out a USB cable and plugging it in.
