Why is it that your phone hits 2% about 15 minutes before you know you're going to have access to power? It's almost as if the phone knows that you will be out of touch for a while. You can carry a large battery with you all the time, but that is inconvenient, especially if you don't have a laptop bag with you.

911 Boost offers a solution to this problem: a small backup battery that can clip directly onto your keys. About the size of a keyfob, this battery can recharge your phone without the need for cables or wall outlets, while not weighing you down. It is available now for $24.99.
