The output voltage and current of mobile phone chargers vary depending on the model and brand, but the majority of ordinary mobile phone chargers typically have an output voltage of 5V and an output current between 0.5A-2A.
Here, the concepts of voltage and current need to be explained. Voltage is a measure of the electronic volt (V) of electrical energy, referring to the electromotive force and the potential difference between two points in a circuit. The current is a measure of the cross-sectional flow of charges per unit time, measured in amperes (A). The output voltage of the charger determines the potential difference generated by the charger during operation, while the output current represents the speed at which the charger transports charges per unit time.
To ensure compatibility between the charger and battery, the output voltage matches the battery charging voltage, and the output current needs to meet the relationship between the minimum charging current of the battery and the maximum output current of the charger. Therefore, the voltage and current of the charger are designed according to the requirements of the mobile phone battery.
Overall, most mobile phone chargers have an output voltage of 5V and an output current between 0.5A-2A; If it is a fast charging charger, the output current will be higher, some even reaching 3A or higher, to shorten the charging time.
