I want to preface the following review, that I am not an expert in Electrical ...
definitely reaches the charging current is not sufficient to my Samsung Galaxy S2 in operation (with navigation app, GPS, Internet, display on, etc.) to load let alone to keep the charge level. Possibly it is indeed the car or on the phone or the adapter ????
I dache Autoanzünder are somehow standardized. Since I do not drive a car exotic, I have been surprised that the adapter rather in the "box" rumwackelt. While it's not so bad that the contact breaks, but firmly, you can not call it.
