Smarter Charger

Most chargers continue to consume power even when they are not in use, but the Zero Charger eliminates this waste by turning itself off. Intended primarily for use with cell phones, the Zero uses a USB port to deliver electricity and can sense when no device is attached. If that happens, it stops drawing power from the wall socket.
