Little Black Box Powers Your Mobile Devices with AA BatteriesWhitson Gordon  — We've shown you how to make your own battery-powered USB charger, but if you aren't up to the task, the Little Black Box will charge and power all your USB devices with a few AA batteries, and without taking up much space.If you just find yourself in a lot of situations where outlets aren't available, you may long for the days when you could just pop a few AA batteries into your device to get it back to full power. The Little Black Box is a very small battery case that plugs into any USB device, giving it the power it needs to keep going. It'll set you back $30, but if you're, say, a frequent traveller and that smartphone isn't lasting you a whole plane ride or two, it's well worth the price—despite how retro it may feel to stick AA batteries into your iPhone.
