The Chargers (or the LED ring) lights up in different colors. White is out, red is willingness Orange is charging and Gründ is loaded. It bothers nor when driving at night.
The only drawback: The cable is indeed a spiral cable but much leeway you have not. But every car has determined any shelf near the cigarette lighter.
All in all it's a solid and well-made charger for the iPhone and Co. While it might be slightly cheaper but quality just comes at a price.
