This charging station is unable to load the phone faster than it discharges in a powered navigation app.
Say:
In Here Drive + the Lumia920 is empty after 2/1 / 2h, although it loads.
In Navigon Europe even after 1h.
A full charge of the Lumia 920 thus lasts more than 4 hours. This applies only if the phone otherwise does nothing (no navigation for example).
This accessory is therefore expressly not for those who want to use their mobile phone while driving as a navigation solution. More for those who are looking for a holder for your phone charging function, if they want to make calls from time to time.
The only alternative is to additionally connect a USB power cable to the phone. But I do not need this expensive NOKIA equipment.
Anyone who has since devised this misconstruction ?!
