Charger:
The amperage of the charger adapter is a bit too low.
If one has the same GPS and UMTS on (Google Maps, Google Navigation) and the display for high visibility on full brightness, then the mobile discharges despite charging adapter connected.
While this is happening relatively slowly, but I think it is a bit disappointing (a point deduction).
The length of the charging cable may be slightly longer. "Corkscrew cable" can be stretched, but still a bit short sized (30 to 40cm).
Summary:
For me in the car as Nothaken more than adequate.
Although a pity that the charging function is not optimal, but I was in the last car rental infinitely glad to have had this charger adapter and bracket, as no other car despite Navi Description (Flinkster, Munich City Transport).
