How to use

Select the output voltage that matches your device (3–12 V) and connect the appropriate adapter tip to the device input. Plug the power supply into a 100–240 V AC outlet and verify the LED indicator for correct operation. Ensure the device’s required current does not exceed 600 mA. If the adapter or device becomes unusually hot or the LED indicates a fault, disconnect immediately and inspect connections or device compatibility.

Usage recommendations

Use only the connector that fits securely into the device socket and confirm polarity before connecting. Do not exceed the maximum output current of 600 mA and avoid using the adapter in damp or unventilated environments. For long-term powering, verify that the selected voltage precisely matches the device specification to prevent damage.
