This article fell into complete failure after 2 months with signs of malfunction. The seller 2URDOOR simply denied warranty and amazon never ceases to make me believe that I will receive a credit. 23 days after my return I still have not been refunded despite the promises of the agents on the phone! Bad choice for this charger even though it is a Samsung product. Keep driving on the item and the seller who certainly book quickly, but that does not honor the warranty !!!
