8ware USB Sync & Charge 1m Cable for Micro USB Devices with Blue LED Indicatior
The USB charge and sync cable is a standard 30 pins & Micro USB cable with a trick up its sleeve: it actively monitors your Android device’s battery level. As the battery reaches its full capacity, the cord glows in a series of running LED lights, getting slower the longer it charges.
When the battery is full, the LED lights switch off, letting you know that your phone’s ready. This little trick is achieved by a string of LED lights built into the plastic section of the cable itself. As your phone charges, the alternating pattern simulates running lights, giving a colourful visual indication of the level of charge in your mobile phones. Since LED lights use a tiny amount of electricity, the loss to the charge itself is negligible. Not only do the lights shut off once your battery is fully charged, the cable keeps an eye on the battery itself, periodically shutting down.
