I was looking for a car charger, which charges my phone while driving, during the phone navigates.
I had previously to provide an adapter that does not have enough power to it (the phone was despite charging adapter empty). According to the data (2.1 A charge current) should work with this new adapter!

But does not it! Even with this adapter, the mobile phone is behind empty as before driving.
What does the (slow) charging, if the phone is not turned on. But that was my old adapter already ...

The good news: There are other adapters to buy at Amazon, where the data is correct also, and the phone is actually loaded (I have a third time bought one and make sure that more than a hundred reviews what nobody writes of insufficient charging current , tested and had success).

So folks, this adapter not buy and find another useful - which you get here at Amazon and also less than 15. Good luck!
