You・ve got something important to do but your batteries are almost out of power. We・ve all been there and each of us has discovered ways to milk every ounce of power out of our devices. I・ve found power cycling my iPhone gives it a few more minutes, but what if someone could give your device a jumpstart? The Jump-Start CARD lets one device siphon off power from another. Yea, can・t decide if this is really useful.
