The charging plug is great, my iPhone and Galaxy can now in the car at the same store, but only if I do not use the cable from Belkin.
Although it is indicated that a cable is plugged in, but it is more likely discharged as charged.
Did it then tried still in the house with an original Apple connector (outlet USB) and the laptop: same result.
With an original Apple USB cable it comes.
Will it but keep me anyway, because I want to have the adapter.
Conclusion: As a precaution an Apple USB cable with order, then there is no problem
