The ChargerLeash Charge and Sync Smart 30 Pin Cable with Loss Prevention Technology for Apple iPhone, iPad, and iPod. Our patented Loss Prevention Technology is a fully functional, high-performance charge and sync Apple 30 pin cable with built-in intelligence that pairs or "leashes" your iPhone, iPad or iPod with any USB charger. If your device is disconnected from the cable (charging source) the ChargerLeash will alert you within seconds using an audible alarm. No more chargers left behind in hotel rooms, meeting rooms, airports or even at home as you rush out the door for that important trip. The ChargerLeash also works as an anti-theft device to keep your iPhone secure from would be thieves that might walk away with your Apple smartphone or tablet while charging in public places.
