Power Bank Module 2xUSB 5V 2.4A USB-C A compact module designed for building a portable power source (power bank). The circuit is intended for use with popular Li-Ion 18650 cells with a nominal voltage of 3.7 V (maximum 4.2 V). The module allows parallel connection of cells to increase the total capacity of the battery pack. It has a built-in LED display that shows the current charge level, charging and discharging status, and which port is in use. The device features an extensive connector panel, consisting of two USB A outputs with support for fast charging (FastCharge and QuickCharge) and three inputs for replenishing energy: USB-C, micro-USB, and Lightning. The maximum charging current is 2.4 A. Example applications * Building portable power banks based on Li-Ion 18650 cells * Emergency power for electronic circuits and LED lighting systems * Portable power sources for mobile measurement devices * Reviving worn power banks by replacing the control module * Powering circuits that require standard USB A interfaces Key technical features * Compatible with cells: Li-Ion 3.7 V (maximum 4.2 V) * Maximum charging current: 2.4 A * Output connectors: 2x USB A (QuickCharge and FastCharge support) * Input connectors: USB-C, micro-USB, Lightning * Overcharge protection: 4.20 V ±0.05 V * Over-discharge protection: 3.00 V ±0.10 V * Current draw (active / standby): below 60 µA / below 50 µA * Module dimensions: 68 x 27 x 10 mm Benefits * Versatility thanks to three popular charging connectors on one PCB * Enhanced safety with built-in overcurrent protection and against over-discharge and overcharge * Clear readout of operating parameters from the integrated LED display * Time savings through support for fast charging standards for connected devices * Compact dimensions for easy installation in enclosures with limited space Note: When connecting cells to the B+ and B- pads, correct polarity must be strictly observed. Reversed polarity will damage the module. https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-05-09 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-05-10 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-05-11 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-05-16 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-05-27 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-05-29 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-12 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-13 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-14 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-15 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-16 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-18 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-19 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-23 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-24 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-27 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-06-29 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-07-01 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-07-07 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-07-16 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-07-24 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-07-26 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-07-29 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-08-08 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-09-11 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-09-24 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-10-04 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-10-21 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-10-23 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-10-24 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-10-29 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-11-03 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-11-04 https://elecena.pl/product/30234017/power-bank-module-2xusb-5v-2-4a-usb-c 2026-11-05
