After replacing everything as expected

As others have written, interferes with the part with me massively on the radio. In principle, I can not hear more radio if I want to charge my phone, because then it just roars. Really a pity.
The power is not enough to charge an Xperia Z while it is in operation (as Navi).
And the stop at the cigarette lighter is also rather poor.
All in all, AUH for the cheap price not worthwhile.

Update:
Today I call from a nice HandyNow get and it is very hard to locate the fault. Mir will be sent to test a new adapter. Really nice service! Maybe my problems really lie only in a defective adapter.

Update2:
After I was able to test some replacement items now I'm quite satisfied. The new adapter no longer interferes noticeably with radio reception and even charging the Xperia Z works, although a bit slow and depending on the "hunger for energy" of the Z only the current battery level is maintained, but on the whole, I'm still very satisfied. The Z is quite high demands on the charger, with my Belkin charger I can not charge the Z also, so far, the performance of mumbi perfectly fine!
