Who goes out with their iPhone charger? nobody, that’s who. And who’s forever crying, wish they had? yeah, that’s what we tend to thought. however we tend to bet that if you’d had the ChargeCard, which is the same dimensions as a mastercard (only a little thicker, of course), you may have saved yourself a couple of hours of hand wringing once your phone died following a marathon session of Candy Crush. It’s $25 and works with pretty much every iDevice and robot machine.
