Apple's new Lightning connector for the iPhone 5 is great, but it's just so darn expensive. If you're looking to save a few bucks, Bloomberg Businessweek discovered a cheaper cable hidden away on Apple's web site.
Apple sells two Lightning-to-30-pin adapters: one that retails for $39, and another that costs $29. They'll both connect your iPhone 5 to your old charging cables, but at an absurdly expensive price. However, Apple sells another, less publicized product: the regular ol' Lightning-to-USB cable, which costs only $19.
You already have a bunch of old chargers that come with USB-to-AC adapters, so the USB cable is all you really need to charge your iPhone 5. It isn't highly publicized on Apple's site, but it's there, and it's better than shelling out $30 or $40 just to charge your phone. Hit the link below to check it out.
