A04I PQ31 2-in-1 PD3.1 Fast Protocol Charge Trigger Decoy Voltmeter

1. Introducció

The A04I PQ31 is a versatile 2-in-1 device designed for testing and triggering various fast charging protocols. It functions as both a fast charge trigger and a decoy voltmeter, capable of inducing specific voltages from compatible chargers and power banks. This device is ideal for aging tests, quality identification, and monitoring voltage and current output from fast charging sources.

It features a voltage gear and mode power-off memory function, ensuring that your last settings are retained. The integrated display accurately shows the current voltage and load current values.

2. Característiques

• Wide Protocol Support: Supports PD3.1/3.0/2.0, Qualcomm QC3.0/2.0, AFC, and FCP fast charging protocols.
• Voltage Induction: Capable of inducing voltages from 5V up to 28V depending on the protocol.
• Visualització en temps real: Digital display shows current voltage and load current values.
• Funció de memòria: Retains voltage gear and display mode settings after power-off.
• Múltiples interfícies: Equipped with USB-A Male (A-IN3), USB-C Male (C-IN1), USB-C Female (C-IN2), and USB-A Female (A-OUTPUT) ports.
• Testing and Aging: Suitable for testing charger stability and performing aging tests on power supplies.

3. Setup and Interface Overview

Before operation, familiarize yourself with the device's interfaces and controls:

• A-IN3 Male Input: Connects to fast charging devices such as QC/AFC/FCP protocol chargers, power banks, etc.
• C-IN1 Male Input: Connects to fast charging devices such as PD3.0 chargers and power banks.
• C-IN2 Female Input: Connects PD3.1/3.0 chargers, power banks, and other fast charging devices through a dedicated fast charging cable. Only this port supports the 28V voltage output of PD3.1.
• A-OUTPUT: Connects to constant current loaders or devices for testing.
• Tecla de canvi de mode: Cycles through three display modes: DUI (Voltage & Current), D-U (Voltage only), D-I (Current only).
• V+ Key Button: Used to increase the induced voltage.
• V- Key Button: Used to decrease the induced voltage.

4. Instruccions de funcionament

4.1 Connexió del dispositiu

1. Connect the appropriate input port (A-IN3, C-IN1, or C-IN2) of the PQ31 to your fast charger or power bank.
2. (Optional) Connect a constant current loader or the device you wish to test to the A-OUTPUT port.
3. The device will power on automatically and display the current voltage o actual.

4.2 Canviar els modes de visualització

Premeu el botó Tecla de canvi de mode to cycle through the display modes:

• DUI: Displays both Voltage i Actual.
• D-U: Volum de visualitzaciótage només.
• D-I: Displays Current only.

4.3 Inducing Fast Charging Voltages

Utilitza el V+ i V- buttons to trigger specific fast charging voltages from the connected power source.

• V+ Key Button:
  • Un sol clic: Sends the voltage upshift protocol, incrementing the voltage.
  • Double-click or Long Press: Cycles through common fast charging voltages: 5V → 9V → 12V → 15V → 20V → 28V.
• V- Key Button:
  • Un sol clic: Sends the voltage downshift protocol, decrementing the voltage.
  • Double-click or Long Press: Cycles through common fast charging voltages in reverse: 28V → 20V → 15V → 12V → 9V → 5V.

The device will attempt to induce the selected voltage based on the capabilities of the connected charger and the protocol it supports.

5. Especificacions

6. Solució De Problemes

• Sense pantalla/Sense alimentació: Ensure the device is properly connected to a power source (charger or power bank). Check if the power source itself is functional.
• Cannot Induce Desired Voltage:
  • Verify that the connected charger supports the desired fast charging protocol and voltage. Not all chargers support all protocols or the maximum 28V output.
  • Ensure you are using the correct input port. The C-IN2 female port is required for PD3.1 28V output.
  • Try a different fast charging cable, especially for high power outputs.
• Lectures inexactes: Ensure connections are secure. If readings seem consistently off, try with a different known-good charger or load to verify.
• Sobreescalfament del dispositiu: While designed for testing, prolonged use at maximum load or voltage may cause warmth. Ensure adequate ventilation. Discontinue use if excessive heat is detected.

7. Manteniment

• Keep the device clean and dry. Avoid exposure to moisture or extreme temperatures.
• Do not attempt to disassemble or modify the device, as this may void any potential warranty and could cause damage.
• Store in a safe place away from direct sunlight and dust when not in use.
