The core principle of fast charging is to increase the charging power by either raising the voltage or the current. There are several methods to achieve this:

1. High Voltage: Increases the voltage to speed up the charging process.
2. High Current: Increases the current to deliver more power to the device.
3. Bidirectional Adjustment: Adjusts the voltage and current according to the device's needs to enhance efficiency.
