The charger includes an integrated 30-pin connector to juice up your iOS devices in a 7-millimeter thick package. At 400 mAH capacity, it won’t be able to charge up multiple devices like a mophie, but it will give you a bit more Angry Birds playing time. One additional bonus: This charging card has an integrated LED flashlight.

Yours for $11.99. Good deal.
