Mobile Power Supply Motherboard 1 Set DIY Fast Charging Module with TFT Color Screen for Maker Labs and Workshops

Description: 1. Four-level safety design: Offers overcharge, over-discharge, high-voltage, and overheat protection via intelligent electronics to ensure safe operation. 2. TFT color display: Live monitoring of charge, voltage, and temperature. Status is instantly visible. 3. Board-level integrated protection: Solder battery directly to mainboard—no need for added protection boards, simplifying the structure and reducing space. 4. Intelligent power indicator: Auto-calibrates after first use to ensure battery percentage accuracy. Specs: Product: 22.5W fast charge board Input: 5V 3A, 9V 2A, 12V 1.5A Output: 5V 3A, 9V 2A, 12V 1.5A, 10V 2.25A Connections: 1 Type-C (bi-directional fast charge) + 2 USB fast output Highlights: Overheat/overcurrent/overcharge/overdischarge/overvoltage protection, excellent conversion ratio, voltage and current are stable Construction: Plastic & metal Dimensions: 62mm x 25mm Included: one set per package Please note: 22.5W refers to super-fast charge protocol; PD20W protocol supports both ways. All interfaces cannot output fast charge simultaneously. Assembly Details: 1. Fragile screen, so always power on and check after tinning. Mishandling or applying pressure can shatter the display. 2. Always solder battery leads—twisting wires, crocodile clips, or spring terminals may cause erratic power delivery. Isolate all battery connectors. 3. Solder B+ to positive, B- to negative; incorrect connection can irreversibly damage the PCB and control IC. 4. Only parallel 3.7V lithium batteries allowed. Series setup or lithium iron phosphate cells will destroy the motherboard. 5. The board’s own protection circuit makes additional battery protection unnecessary—external protection boards may introduce output limits. Disclaimers: 1. Actual product color can vary from pictures due to display and lighting differences. 2. Expect minimal measurement variance from 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.
