22.5W Fast Charging Power Bank Circuit with 5 Ports, Bidirectional QC4 + PD3.0, 3.7V Input

The 22.5W Fast Charging Power Bank Circuit with 5 Ports, Bidirectional QC4 + PD3.0, 3.7V Input is an advanced power management circuit designed for high-performance and efficient power distribution. This circuit supports fast charging protocols such as Qualcomm Quick Charge 4 (QC4) and Power Delivery 3.0 (PD3.0), allowing users to charge devices rapidly while also enabling the power bank to be charged quickly.

Key Features:

• 5 Charging Ports: Features five USB ports for charging multiple devices simultaneously. The ports support both output and input functions, providing flexibility for a range of devices.
• Bidirectional Charging: Supports bidirectional charging, meaning the power bank can both charge connected devices and be charged itself through the same ports, making it a versatile solution for portable power.
• QC4 + PD3.0 Support: Utilizes the latest fast-charging technologies like Qualcomm Quick Charge 4 and Power Delivery 3.0, ensuring fast and efficient charging of compatible devices, reducing charging time significantly.
• Efficient Power Management: Designed for efficient power distribution to multiple devices, ensuring that each connected device receives optimal power for fast charging while protecting against overheating or overcharging.
• 3.7V Input: The power bank circuit operates on a 3.7V input, typically from a lithium-ion or lithium-polymer battery, providing a portable, reliable power source.
• Compact and Portable: The circuit design is compact and lightweight, ideal for creating custom power banks that are easy to carry and use on-the-go.
