Important Compatibility and Safety Notes
Use a compatible, good-quality single-cell 18650 lithium-ion battery with the correct polarity.
Do not connect a 120V AC supply directly to this module. The board is intended for low-voltage USB charging inputs and a single-cell battery.
The advertised 2.4A output may not be available simultaneously from both USB ports. Verify the manufacturer's total output rating.
Confirm the board's battery connection, charging current, and protection specifications before use.
Why Choose This Power Bank Module?
This module provides a convenient starting point for building a custom USB power bank without designing a boost converter and display circuit from scratch. Multiple input connectors, dual USB outputs, and battery-level indication make it useful for compact DIY charging projects.
