Voltaic solar charger takes tablets
Voltaic has opened the blinds on its latest eco-charger, extending its built-in solar panel love to the realm of tablet cases.
After one hour of sunlight, the Spark will provide an iPad with enough juice for an hour of video playback. Ten hours of sunbathing will charge one fully.
The Spark features a 39W hour battery for storing charge and as with the Scosche goBat II which appeared in our Festival survival gadgets  roundup, has two ports, one for tablets and one for other small handhelds.
The Voltaic Spark  is available Stateside for $299 (£187).
If you're looking for something with even greater power, check out the company's solar-powered laptop case , another eco-charger revealed at CES earlier this year that has now gone on sale for $499 (£305). ®
