AT&T announced yesterday their new green charger. This device powers most low-power USB devices, including the iPhone, and is purportedly the world's first charger to avoid power draw. When a device is full, the ZERO automatically stops charging and therefore avoids a trickle of energy when a device is left plugged in. The interchangeable "block" design also reduces the obsolescence of the charger once owners replace their devices.The packaging itself helps and is made entirely of recycled paper.No pricing has been given, but AT&T expects the ZERO Charger to cost as much as a regular power adapter. It will ship sometime in May.
