Some consumer products leave a lasting mark on the design world, inspiring others to innovate (and in many cases imitate) for generations — a disproportionate number of those things came from Braun, and in particular, industrial designer Dieter Rams. The Braun ET66 Calculator ($50), though an incredibly simple device, is an often-copied piece of industrial design. Go ahead, grab your iPhone and open up the calculator app — it ought to look pretty familiar. While there are plenty of calculators (and apps) out there with more robust functionality, there are none as iconic.
Keep all the excess cable that comes along with your headphones under wraps, while protecting your iPhone, with the Cordli Case ($15-$25). This iPhone case (designed to accommodate an iPhone 4 or 4s) has grooves and clips that weave across its back, letting you stow away 10 to 20 inches of headphone cable. It's perfect for storing shorter headphones while they're not in use, or for taking out some of the slack in a longer cable, avoiding bulk in your pocket. While not yet available, an iPhone 5 case is in the works, and should be ready soon. Available in blue, black, or white.
Make dead devices a thing of the past with the Dark Energy Reservoir ($129). You've all been in situations where your smartphone, tablet, or camera needed some extra juice — whether you're traveling on a plane, train, or bus, you're in an emergency scenario, or you're outdoors miles from an outlet. This slim, portable charger holds enough power to charge the average smartphone for an entire week, and it does it as fast as a wall outlet. With the ability to charge two devices at once, and compatibility with any USB charging device, you'll never have to worry about charging again.
