The Dual USB 5V 2.4A Power Bank Charger Board is an advanced DIY charging module featuring an integrated backlit LED digital display screen. Designed for 3.7V lithium-battery setups (like parallel 18650 cells), it provides dual USB output ports alongside Type-C, Micro-USB, and Lightning input options. The smart controller delivers safe, steady 5V 2.4A output distribution while the real-time numeric display shows exact battery percentage, input status, and active load monitoring.
Full Product Description
The Dual USB 5V 2.4A Power Bank Charger Board (Model H961-U V6.1) is an advanced, highly integrated power management module designed for creating custom 3.7V lithium battery banks. This versatile board features a built-in backlit LED digital display screen that provides a real-time numerical percentage readout of remaining capacity, along with clear “IN” and “OUT” active status indicators. This all-in-one motherboard manages battery charging, stepping up voltage, and safety shutoffs, eliminating the need for complex multi-board wiring configurations.
Engineered with exceptional connectivity options, the board hosts a triple-input layout including USB Type-C, Micro-USB, and Lightning ports, allowing you to recharge the power bank using almost any standard smartphone cable. Dual intelligent USB Type-A outputs deliver a combined 5V 2.4A of power, automatically optimizing the current draw based on your connected device. Its dual-layer design optimizes circuit board real estate, making it easy to fit into compact custom housings or 38650/18650 3D-printed battery cell enclosures.
Key Product Features
- Real-Time LED Digital Readout: Provides an explicit numerical battery level percentage indicator (0% to 100%) alongside operational input/output icon indicators.
- Triple Universal Input Ports: Incorporates Type-C, Micro-USB, and Lightning ports to give you total flexibility when recharging your power bank.
- Dual Smart Current Balancing: Dual USB ports intelligently distribute a stable 5V 2.4A output to charge up to two small consumer electronics devices simultaneously.
- High Efficiency Step-Up Design: Employs a low-profile synchronous 2R2 power inductor to optimize DC-to-DC conversion efficiency and minimize heat generation.
- Integrated Safety Shield: Features hardwired on-board protections against battery over-discharging, input overcharging, overcurrent, and short circuits.
