Product Specifications:

3A (battery side) high-efficiency charging

2.4A maximum output current

Fixed 5V output (always on)

Standby power consumption <150μA

Module Terminal Definitions:

Type-C Port: Module 5V power input terminal (protocol-free when drawing power for output)

USBA Port: Module 5V output terminal (charges phones and powers devices)

5V: Module 5V output positive terminal solder point (can also serve as input connection)

-: Module 5V output negative terminal solder point (can also serve as input connection)

B+: Module battery positive terminal solder point

B-: Module battery negative terminal solder point

Note: The buttons on both modules only activate the LED indicator when it is off. They cannot control input/output or turn off the LED indicator.

Precautions:

1. Reverse battery connection will damage the board. Ensure correct polarity. Soldering is required for normal operation. Discharge static electricity from the soldering iron and your body before soldering.

2. In no-load standby mode, the module optimizes power consumption and detects input voltage by periodically dropping to ~4.8V and briefly rising to 5V every few seconds to check for load connection.

3. All connections must be soldered. Use thickest and shortest wires possible; do not insert intermediate switches.

4. Higher power usage approaches the maximum current rating, increasing heat generation. Ensure adequate heat dissipation during operation.

Frequently Asked Questions:

1. Can the module function as a UPS or provide seamless input/output switching?

Answer: When input is disconnected, a brief switching time occurs between input and output due to circuit design.

2. Can it charge and discharge simultaneously?

Answer: Input and output share the same port. When input voltage is present, output voltage is also generated. Ensure sufficient input power to prevent instability.

3. What does the button do?

Answer: The button only displays voltage usage. It has no other functions. In standby mode, the battery indicator light turns off. Press this button to check the battery level.

4. Can the Type-C port charge phones?

Answer: We recommend using the USB port for phone charging, as it's universally compatible. While Type-C can charge Huawei, Xiaomi, and similar phones, certain models like Apple and Samsung require protocol chips for charging to initiate (the module outputs power but these models need chip recognition). Using the USB port ensures compatibility without issues.
