Our iPhone batteries always seem to send us that 10% warning at the worst of times. Most recently, when we were on an elevator and hoping to avoid creepy-guy-eye-contact by playing Draw Something. Fortunately for us, we just invested in a Solar-Powered Battery Pack ($39). Solar power isn't a new concept, but having it at our fingertips is certainly convenient. We'll keep this little keychain close!
