6. Setup
- Identify Device Requirements: Before connecting, determine the exact voltage (V) and current (A) requirements of your electronic device. This information is usually found on the device itself, its original power adapter, or in its user manual.
- Select DC Connector: Choose the appropriate DC output connector from the 14 included tips that fits your device's power input port.
- Connect DC Connector: Firmly attach the selected DC connector to the output cable of the adjustable power adapter.
- Check Polarity: The default polarity is inside positive (+), outside negative (-). If your device requires the opposite polarity, use the provided reverse polarity conversion cable by connecting it between the adapter's output cable and the chosen DC connector.
- Set Voltage (BEFORE Connecting to Device): Plug the power adapter into a standard AC wall outlet. Rotate the voltage adjustment knob on the adapter to set the desired output voltage, as identified in step 1. Observe the LED digital display to ensure the voltage is set accurately.
- Connect to Device: Once the voltage and polarity are correctly set, connect the DC output connector to your electronic device.

This image emphasizes the real-time voltage display screen on the power adapter. It serves as a reminder to power on the supply and set the target voltage using the rotary knob before connecting any device, ensuring safe operation.
7. Operating Instructions
Once the setup is complete, operating the power supply is straightforward:
- Power On/Off: The voltage adjustment knob also features an 'OFF' position. Rotate the knob fully counter-clockwise to turn off the power supply without needing to unplug it from the wall. Rotate clockwise to turn on and adjust voltage.
- Voltage Adjustment: To change the output voltage, first disconnect the adapter from your device. Then, rotate the voltage knob to the desired setting, monitoring the LED display for accuracy. Reconnect to your device only after the voltage is stable at the correct level.
- Continuous Monitoring: The LED display continuously shows the output voltage, allowing you to confirm the operating voltage at any time.
8. Maintenance
- Cleaning: Disconnect the adapter from power and devices before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or solvents.
- Storage: Store the adapter and its accessories in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending or crimping the power cables excessively. Do not place heavy objects on the cables.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Incorrect voltage setting. | Verify and adjust the output voltage to match your device's requirements. |
| Incorrect polarity. | Check your device's polarity requirements and use the reverse polarity cable if necessary. | |
| Loose connection. | Ensure all cables (AC input, DC output, and tip) are securely connected. | |
| Device current exceeds adapter's limit. | Ensure your device requires 6A or less. If it requires more, this adapter is not suitable. | |
| Adapter LED display is off. | Adapter is not receiving power or is turned off. | Check if the adapter is plugged into a live wall outlet. Ensure the voltage knob is not in the 'OFF' position. |
