Those like me who has had enough of cheap parts that disintegrate either do not work or even worse, when used in all the items that you should treat yourself this well-made charger.
The usable cable length is approximately 40 to 50 centimeters. One can stretch to about 1 meter in length, the spiral cable though, the train on the plug for the cigarette lighter or the iPhone connection is then so great that dissolves the plug connection.
So remeasure in doubt before ordering better in your own car, if the cable length is sufficient to your requirements. Since my phone is deposited in the tray in front of the gear lever and right next to the cigarette lighter, the short spiral cable is sufficient for me. Up to a holder on the windshield, it would probably not long.
