On the one hand the Micro USB piece does not fit properly in the Galaxy S4. It's always kind of not making contact available so that it beeps continuously and the battery charge is constantly interrupted and begins anew and is again interrupted.
If one then fixes the Micro USB piece with a rubber band, although there is no loose contact, but also the adapter does not really seem to be original Samsung goods. The Battery charging time greatly exceeds the charge time with the charger that came with the phone.
Product name "seems" While consistent, but that does not mean anything ... yes
I'd rather spend one or two euros more and buy directly from Samsung.
