In yet another entry in Android Community's "why didn't I think of that" series, accessory maker Dexim has a new product that should help you stay green and keep a watchful eye on your phone's battery. The Visible Green USB charge and sync cable is a standard MicroUSB cable with a trick up its sleeve: it actively monitors your Android phone's battery level. As the battery reaches its full capacity, the cord glows in a series of running lights, getting slower the longer it charges .When the battery id full, the lights switch off, letting you know that your phone's ready.
