Will a high-power charger break the phone? The answer is: No. Because when the charger is charging the mobile phone, they will conduct a series of communication and exchange, and can adjust the voltage and current at any time. For the charger using USB-A interface to charge the mobile phone, the two will report the "connector code" respectively. If it is matched, it will be charged, and if it is not matched, it will refuse to charge; If the USB-C port charger is used for charging, the communication between the mobile phone and the charger will be more frequent, accurate and continuous to ensure the best charging scheme.
The power parameter of the charger is one of its performance indicators, indicating how much output power the charger can achieve.
To use a simple and understandable example, the charger is a car, and the output power of the charger is how fast the car can drive (200 kilometers per hour). The mobile phone is like a driver. He controls the accelerator pedal of the car.
How fast the car drives depends on the driver's needs. You can drive slowly to buy vegetables, and you can drive at a speed of 120 kilometers per hour. The output power of the charger also depends on the mobile phone. How much power the mobile phone needs, the charger will output to the mobile phone.
So, don't worry about the high power charger that will damage your mobile phone.
However, do not use some fancy chargers, or 48V, 72V power adapters that are not used to charge mobile phones, or even use 220V to poke mobile phones directly. This will definitely be bad. We must pay more attention.
