The charging current is just 1.2 Ah and therefore falls too low to charge the phone while driving, if you use it at the same time as a navigation device. It discharges more slowly than one would use it without charger, but it is just not loaded.
If the mobile phone but does not continue to be used while driving with any apps, so it loads quite well.
So who is instructed while driving on navigation by mobile phone, which should engage more with the Wicked Chili adapter, which is carried at more than 3000 mAh. I had previously unfortunately overlooked.
Therefore only 3 stars for this car adapter, since it is compatible with the mentioned smartphones. To load, however during use unsuitable and therefore rather not recommended.
