Shaped like a business card, Charge Card is actually a USB cable for iPhone. As thin as 0.1″ (2.54mm), it perfectly fits into your pocket, wallet and purse. Whenever you need to charge your iPhone, take it out, pop open its ‘cable arm’ and plug it into a USB port. As simple as that! Charge Card’s creator Noah Dentzel and Adam Miller are also working on an Android version. I like its sleek and practical design. What do you think?
