Product Interface Introduction Diagram
Figure 2: Product Interface Introduction. Labels include A-IN3 Male input, C-IN1 Male input, C-IN2 Female input, A-OUTPUT, Mode Switch Key, V+ Key Button, and V- Key Button.
  • 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 to PD3.1/3.0 chargers through a dedicated fast charging cable. Fast charging devices such as power banks only support PD3.1 with this feature (28V voltage output). This port is specifically designed for 28V voltage output of PD3.1.
  • A-OUTPUT: Connected to constant current loaders, etc.

To begin, connect the PQ31 to your PD3.1 protocol charger, power bank, or other compatible device using a dedicated data cable (preferably with an E-marker for PD3.1). The display screen will light up upon successful PD3.1 protocol handshake.

5. Operating Instructions

Button Functions:

  • MODE Key: Short press to cycle through the three display modes: DUI (Voltage/Current alternate), D-U (Voltage only), and D-I (Current only). Ensure a dedicated fast charging cable is connected to the C-IN2 port during PD3.1 operation.
  • V- Key Button: Click to send a voltage downshift protocol. Double-click or long press to cycle through fast charging voltage protocols in descending order (28V-20V-15V-12V-9V-5V).
  • V+ Key Button: Click to send a voltage upshift protocol. Double-click or long press to cycle through fast charging voltage protocols in ascending order (5V-9V-12V-15V-20V-28V).

Display Modes:

  • DUI Mode: Displays voltage only when there is no load output. When a load is connected, voltage and current are displayed alternately.
  • D-U Mode: Displays voltage only.
  • D-I Mode: Displays current only.

Power and Voltage Memory Functions:

The PQ31 incorporates both power-off memory and voltage memory functions to enhance testing efficiency.

  • Power-off Memory: The device remembers the last measurement mode used. Upon next power-on, it automatically recalls this mode, significantly reducing setup time for repetitive tests.
  • Voltage Memory: When you manually adjust the voltage and then power off/on the device, it will recall the previously stored voltage. This allows for intelligent and automatic negotiation of the corresponding protocol to activate the stored voltage, ensuring fast charging.

PD3.1 28V Testing Method:

To conduct a 28V test, you need a charger that supports PD3.1 28V. Insert a dedicated test line with an E-marker chip to conduct the 28V test through the PQ31 voltage bus terminal (C-IN2 female input).

7. Important Warnings and Safety Information

WARNING:

This device is designed to extract high voltages from fast chargers, power banks, and other devices that support the PD protocol. The output voltage can be relatively high (e.g., 9V, 12V, 15V, 20V, 28V), which is not suitable for directly charging ordinary mobile phones that typically support only 5V. Incorrect application by the user, such as directly inputting high voltage into an ordinary mobile phone, can cause damage to the phone.

The PQ31 is not a charging accelerator. Instead, it induces the voltage of PD protocol products by simulating the standard PD handshake protocol of mobile phones. Its purpose is to help identify true PD protocol compatibility and can be used for aging testing with an electronic load. Always ensure the total power requirements are met when using the induced voltage to power other devices.

8. User Tips

  • Always use a dedicated E-marker cable for PD3.1 28V testing to ensure proper communication and safety.
  • When testing, start with lower voltage triggers and gradually increase to avoid unexpected issues with the power source or load.
  • Utilize the power-off and voltage memory functions for repetitive testing scenarios to save time and improve efficiency.
  • The PQ31 can be a useful tool for repurposing old fast chargers to power other devices (e.g., routers, optical modems) that require specific voltages, provided the total power consumption is within limits.

9. Troubleshooting

  • No Display/No Power: Ensure the PQ31 is correctly connected to a compatible fast charger or power bank. Check the cable for damage.
  • Incorrect Voltage Triggered: Verify that the connected charger supports the desired protocol and voltage level. Some chargers may not support all advertised voltage steps (e.g., 15V or 20V for some PD chargers).
  • Inaccurate Readings: Ensure connections are secure. If issues persist, refer to the official PDF manual for advanced calibration or contact support.
  • 28V Trigger Failure: Confirm that both the charger and the cable (E-marker required) support PD3.1 28V. Use the C-IN2 female input for 28V output.

10. Maintenance

  • Keep the device clean and free from dust and moisture.
  • Avoid dropping or subjecting the device to strong impacts.
  • Store in a cool, dry place when not in use.
  • Do not attempt to disassemble or repair the device yourself, as this may void any potential warranty and could cause damage.
