Solar charging is everywhere now, from cars to houses and now even tablets, that get a special case with that ability. I’m talking about the Voltaic Spark tablet cases, making your iPad greener than ever. The product sells for $299 and it’s pictured below.

This accessory comes with an 8W solar panel on the back, that charges an internal battery. These panels can take on water and they’re rugged enough to take on a trip outdoors. To give you an idea of the performance of this case, know that the iPad’s battery can be fully charged if left in direct sunlight for 10 hours.

Other slate models may even take less time and we have to mention that the internal battery can charge two devices at the same time. The Spark Tablet Case also comes with 5 adapters, increasing its compatibility, plus two USB ports. You can also use this case to hold the tablet in landscape mode for better video viewing, as shown above.
