Take Honor 10 and Huawei p20 charger as an example, the two charger models are the same, the DC output of the charger is: 5V\/2A or 4.5V\/5A or 5V\/4.5A, it can be said that there is basically no difference between the two chargers.
The charger can be divided into power frequency machine and high frequency machine according to the working frequency of the design circuit. The power frequency machine is designed based on the traditional analog circuit principle, the internal power devices (such as transformers, inductors, capacitors, etc.) are larger, and there is generally less noise when the load is larger, but the model has strong resistance performance in the harsh grid environmental conditions, and the reliability and stability are stronger than the high-frequency machine.
