Generally speaking, Samsung a54 chargers are divided into two kinds, one is the charger that supports 12V/2A output voltage and maximum 2.5A output current, and the other is the charger that supports 10V/2A9V/2A output voltage and maximum 2.5A output current. These two types of chargers have different output voltages and currents for different devices, as well as different charging speeds and efficiencies. When choosing a charger, you need to choose the right charger according to the charging needs of the device and the power supply to get the best charging effect and safety.
