Imagine the scene: You’re in the middle of a particularly intense iPhoneography session, and the photos you’re getting are gold. You snap one keeper after another and then shift over to SnapSeed or some such app to really spice things up. But you’re so engrossed in the process of editing that you don’t notice your iPhone’s battery is almost dead until you get the dreaded pop-up warning.
If you are equipped with Photojojo’s keychain backup charger, then you needn’t worry. Just flip the top, plug it in and continue working.
