The Sun Is Basically an Infinite Battery for Your iPad Now

Nothing kills a magical afternoon with your tablet like having to track down an outlet to charge up. Voltaic's new solar-charging tablet case is designed specifically to keep your magical device off the on-grid energy teat.

The Spark tablet case gets an hour of iPad video playback for every hour of direct sunlight, coming to 10 hours for a complete charge, which is actually pretty good compared to other solar chargers, and great considering how small the case is. Its form factor is designed to fit your tablet, but it charges through USB, so you can hook up pretty much anything to its 39-watt hour battery. Just remember to get out of the direct sunlight while you're trying to use your tablet, lest you be caught in some kind of impromptu Kindle viral campaign. [Voltaic via Treehugger]
