Instructions for Use

1. Check the working voltage of your device by referring to its spec label. Make sure it is between 3V~24V DC.
2. Check the max current your device will draw. Ensure it is equal to or less than 1.5A.
3. Choose the correct DC tip for your device from the 14 included tips. If unsure, measure the power input port of your device with a ruler.
4. Plug the chosen DC tip into the output port of the power supply adapter.
5. Connect the reverse polarity converter cable if needed. This cable reverses the internal positive pole to negative and the external negative pole to positive. Confirm the polarity of your device before use to avoid short-circuiting and damaging your device.
6. Plug the power supply adapter into an AC outlet.
7. Rotate the voltage adjustment knob to set the desired output voltage. The LCD display will show the output voltage.
8. Connect the DC tip to your device's power input port.
9. Make sure to use the power supply adapter within 80% of its full load capacity to avoid overheating and shortening its service life.

Troubleshooting Tips

• If your device is not working or receiving power, double-check the voltage setting and ensure it matches your device's required voltage.
• Make sure the DC tip is securely connected to your device.
• Check if the reverse polarity converter cable is needed and connected properly.
• If the power supply adapter is overheating, reduce the load on the adapter by using it with lower power-consuming devices.

Frequently Asked Questions

Can I use this power supply adapter to charge electronic devices with batteries, such as laptops?

No, this product is an AC to DC adapter and not a charger. Using it to charge electronic devices with batteries may damage your device.

Why does the voltage change slightly without adjusting it?

It is normal for the voltage to change slightly when your device is working. Ambient temperature, magnetic field, and signal noise can also affect output voltage. However, the change is slight and acceptable and should not damage most electronics.

What is the purpose of the reverse polarity converter cable?

The reverse polarity converter cable is used to reverse the original polarity of the power supply output port, changing the internal positive pole to negative and the external negative pole to positive. This increases the compatibility of the power supply with various devices.

How can I ensure the power supply adapter lasts longer?

Use the power supply adapter within 80% of its full load capacity to avoid overheating and shortening its service life. Always double-check the voltage and current settings before connecting it to your device.
