This charger with original battery of Samsung for me is the "iron" current reserve. The battery charging via micro-USB cable or USB 3 cable (not supplied) and the charging phase is indicated by a LED. The battery is well protected in the charger and can be transported in the charging cradle (with closing cap). The price is in a very good relationship with the quality. The product offers very good workmanship. The charging station with battery is priced in the same segment as the ACCU solely with well-known shops in the electronics industry. In this regard, were my thoughts. For my purposes, this charger is sufficient.
