This compact printed circuit board is designed to serve as a single-cell Li-Ion battery charger and power-out module. Its USB-C interface provides 5 V from any compliant source, powering an on-board charger IC that supports charging currents of 250 mA, 750 mA, or 1 A*. Two sets of terminals are available:
- Battery In: for charging the battery safely.
- Battery Out: for delivering battery voltage to a load even while the battery is charging.
Note: The charging current will depend on the battery charge percentage.

The USB-C port accepts a 5 V supply from PCs, charger bricks, or power banks.
Integrated safety measures include over-voltage, over-current protection up to 5A, and thermal shutdown.
Up to 3A output current from output terminals. The module can operate with currents above 3A with proper thermal management. Keep the module below 150°C to avoid permanent damage to the device.
