The charger is badged Samsung and after a few weeks of using it continues to fulfill its function: load a Samsung Galaxy phone. It also works without problems for other brands, Sony for example. Strange and annoying especially a Samsung phone is not content with a simple USB charger Lambda, while a Sony model accepts to load up with any standard USB charger. But good to return to the charger, it is perfect, I paid here exactly 10x cheaper than a Samsung dealer.
