⚙️ How the 18650 Dual USB Charging Module Works

The 18650 5V 2.4A Lithium Battery Charging Module integrates multiple power functions into a single board:

1. Battery Charging
   When a power source is connected, the module safely charges the connected 18650 lithium battery using controlled charging logic.

2. Voltage Boost Conversion
   Since a single 18650 cell operates at around 3.0V–4.2V, the module boosts this voltage to a stable 5V output, suitable for USB devices.

3. Dual USB Output
   The module provides two USB ports, allowing users to power or charge multiple devices simultaneously.

4. Digital Display Monitoring
   The onboard digital display shows real-time battery information, helping users monitor remaining capacity or voltage.

This all-in-one functionality makes the module ideal for portable power solutions.
