22.5W 5V 4.5A QC4.0 PD3.0 Dual USB Type C Micro USB 18650 PowerBank Module

22.5W 5V 4.5A QC4.0 PD3.0 Dual USB Type C Micro USB 18650 PowerBank Module is an advanced, high-efficiency bidirectional fast charging circuit board engineered for custom lithium-ion portable power solutions. This controller integrates intelligent multi-protocol fast-charging technology that supports Quick Charge 4.0+, USB Power Delivery 3.0, Huawei SCP/FCP, and Samsung AFC protocols to achieve up to 22.5W output power. Consequently, it enables ultra-fast charging and discharging across a broad spectrum of modern smartphones, tablets, and embedded development systems. Furthermore, the board features five dedicated interface ports, including dual USB Type-A female sockets, a bidirectional USB Type-C port, a Micro USB port, and a Lightning input connector. Therefore, electronics hobbyists and engineers can design versatile, high-capacity 1S battery power banks with comprehensive hardware protection and clear digital status indication.

Pinout and Wiring:

• B+ (BAT+): Solder pad for the positive terminal of the 3.7V / 4.2V lithium-ion battery pack.
• B- (BAT-): Solder pad for the negative terminal of the 3.7V / 4.2V lithium-ion battery pack.
• NTC: Solder pads for an optional 10kΩ temperature-sensing thermistor to monitor battery pack thermal conditions.
• Note: However, connecting batteries in series (such as 2S, 3S, or 4S) will destroy the module, so you must wire multiple 18650 or 21700 cells strictly in parallel.
