Loads very fast, stable

The charger is doing exactly what it should. It invites my Samsung Galaxy S3 on in no time, regardless of whether it runs during which or not. With other charging cables I had there are problems, they invited the phone while on, but so slow that you had partly fear that the mobile phone during use consumed more electricity than it could invite. That's not the case here. The spiral cable may be a bit longer, depending on it is just a bit under tension, but it is not yet further disturbing.
