⚡ Working Principle of 22.5W Power Bank Module QC4.0 Fast Charging

The module first charges the connected lithium battery using a three-stage charging process consisting of trickle charging, constant-current charging, and constant-voltage charging. This ensures efficient charging while maximizing battery lifespan.

When a USB device is connected, the onboard controller identifies the supported fast-charging protocol and negotiates the appropriate voltage and current. A high-efficiency boost converter then raises the battery voltage to the required USB output voltage, allowing compatible devices to receive fast charging while maintaining stable output and built-in safety protections.
