Little Black Box uses AA batteries to power iOS devices

Rechargeable battery packs and cases are great for extending the life of your iPhone or iPad, but what happens when you use up both your device’s battery and your rechargeable battery pack? If you have a QuickerTek Little Black Box, the answer is simple: throw in some fresh AA batteries and go about your business.

QuickerTek’s Little Black Box lets you charge and power your iPad, iPhone or iPod touch with four ordinary or rechargeable AA batteries. Just insert the batteries in the box, plug the box into your device using Apple’s standard USB connector, and you’re good to go.

The $30 device can handle Alkaline, Carbon, NI Metal Hydride or NiZinc rechargeable AA batteries, so long as all your AA batteries are the same kind and brand. QuickerTek says the rechargeable NiZinc batteries are best to use, since they have the highest capacity.

Weighing in at a mere 1.6 oz. without batteries, and boasting a slim, low-profile design, the Little Black Box could make for a useful travel companion, and a good way to put your spare AA batteries to use.
