I’ve seen plenty of supplemental batteries for mobile gadgets, but they’re usually just rectangular bricks without any particular style about them. The guys over at Apel-π (pronounced “apple pie”, of course) decided to do something about it, by releasing a line of external batteries that look like a slice of Apple.
The Opso Slim works with most iPhones and Android phones, while the Opso Plus provides more power, and works with tablets like the iPad and Galaxy Tab and Kindle Fire. The 16mm thick, 3 oz. Slim is powered by a 3200 mAh Li-Po battery, while the fatter, 26mm thick, 7 oz. Plus has double that capacity at 6400 mAh.
