The Dexim Visible Green 2.1 Amp mini car charger includes one Visible Green USB-charger (5V, 2.1A US Plug) and one Visible Green charge & sync cable, but it isn"t your standard 30-pin sync cable. Dexim"s Visible Green charging cables allow you to see the energy current running through the cable. When your device is fully charged, the Visible Green cable"s current will fade as it shuts off power from the source, saving you car"s battery.
