The Car Holder is operated with me in connection with the Lumia 925. For the Lumia 925, a charging Cover for wireless charging is necessary. However, if the navigation of the phone is active, the charging current via the holder is not sufficient. The phone therefore discharges continuously despite charge. Even with mild temperatures around 20 ° C and sunshine my Lumia on the dashboard is so hot that it turns off. That leaves only the desired mechanical strength that may be considered excellent. The holder will not budge. For the heat shutdown of Lumia 925, the holder can not be sure. Nevertheless, it is the simply not met the claim to use high-priced Nokia accessories. The charging function is too weak and the compatible Lumia 925 on starting cold outside. In midsummer, it will get not work well. For people who want to attach a deactivated phone, it is sufficient. Shame
