22.5W Power bank PCBA with Lithium Battery Power and rigid PCB Supply for Mobile Charger

The 22.5W mobile charger PCBA (Printed Circuit Board Assembly) is a power supply module designed for a lithium battery power bank. It incorporates a BC12 fast charging circuit board to enable rapid charging of mobile devices.

Here's a description of the key aspects of this PCBA:

Power Supply and Conversion: The PCBA is responsible for converting the input power source (AC or DC) into the appropriate voltage and current levels required for charging the lithium battery and powering connected devices. It includes power supply circuitry, such as transformers, rectifiers, voltage regulators, and filters, to achieve efficient and stable power conversion.

Lithium Battery Charging: The PCBA incorporates a charging circuit designed specifically for the lithium battery used in the power bank. It employs a charging algorithm that supports fast charging, typically based on industry standards such as BC12 (Battery Charging Specification 1.2). This ensures safe and efficient charging of the battery while preventing overcharging and overheating.

Fast Charging Circuit (BC12): The PCBA includes BC12 fast charging circuit board, which is supported high-speed charging protocols to ensure compatibility with majority of mobile devices. BC12 is a standard devices to negotiate optimal charging parameters, such as voltage and current levels, to achieve faster charging times.

PCB Design and Assembly: The PCBA for the power bank is designed around a printed circuit board (PCB) specifically tailored to meet the power bank's unique requirements. The PCB layout is carefully designed to accommodate the necessary traces, components, and copper layers needed to handle the voltage and current levels involved. Components such as transformers, capacitors, resistors, integrated circuits, and connectors are meticulously assembled and soldered onto the PCB to ensure optimal functionality and performance. This comprehensive approach ensures that the PCBA effectively supports the power bank's operation and delivers reliable power output.
