Heavy Moon out of Japan has released the "smartCharge" adapter for a car cigarette lighter. It appears as though it is designed for use with the iPod shuffle—given the Shuffle is using rechargeable batteries—but theoretically it could be used with almost any rechargeable USB device, just so we don
t want to jump to any iPod-based conclusions. Thirty-two bucks will make this all yours over in Japan.
