TFT Color Screen Fast Charging Module 1 Set DIY Mobile Power Supply Motherboard for Hobby Electronics Making

1. Four-fold intelligent protection: against overcharging, over-discharging, excess voltage, and overheating for assured safety. 2. TFT color screen: displays power level, voltage, and temperature in real time – easily monitor operating status. 3. Integrated safeguard circuit design: protection features are built onto the PCB for direct battery integration, saving room and streamlining the build. 4. Automatic battery power calibration: after initial operation, it self-adjusts for precise power indication throughout use. Specifications Product Title: 22.5W Fast Charge Module Input Specs: 5V3A / 9V2A / 12V1.5A Output Specs: 5V3A / 9V2A / 12V1.5A / 10V2.25A Connectors: 1 Type-C dual-directional charging port, 2 USB quick output ports Features: Complete suite of safety protections, efficient power conversion, reliable voltage, and current supply Build: Plastic, metal Mainboard Dimensions: 62 by 25 millimeters Package: 1 module per set Reminder: 22.5W applies to the ultimate fast-charging protocol, PD20W for two-way charging, and fast charging is disabled when multi-ports are used simultaneously. Assembly: 1. The screen is fragile—test it after tin soldering; improper pressure may damage the display, so handle with attention. 2. Wires must be firmly soldered; alternative connections (twisting, clips, or spring contacts) can lead to reduced performance. Battery terminals must be well insulated. 3. B+ must go to battery positive and B- to the negative side. Reverse connection will destroy the motherboard and leave marks on the IC. 4. Use 3.7V lithium ternary batteries only, connected in parallel. Series connection or lithium iron phosphate batteries will cause hardware failure. 5. The board’s own protection eliminates the need for external protection; external boards may interrupt output if current exceeds limits. Notices: 1. Actual color may differ from pictures due to lighting or monitor variance. Please check the delivered product. 2. Allow minor differences in measurements due to manual measuring. The merchant warrants that their products comply with all applicable laws, and are offered only if they comply with Joom's policies and EU Product Safety and Compliance laws.
