Tips and FAQs:
1. Before buying, check whether your adapter is 12V-24V？gear to avoid wasting your time.
2. Check the voltage of your electronic product to see if it matches the voltage of this product?
3. To supply power to high-power equipment, check that the power of your adapter is greater than the required power supply equipment.
4. It is a Center Positive + power supply. Please kindly check what polarity of your device before bidding. You can find the polarity information printed beside the power port.
5. Normally, bigger Electric current one can be compatible with smaller one. For example, 2A works with 0.5A, 1A or 2A works. Conversely, it can't work on electronics larger than 2A.
How to use correctly:
1. Check the voltage and current of your electronic products, such as 12V 1A, 9V 1500mA...
2. Set the right DC output voltage，For example: The voltage of your electronic product is 9V. Please adjust it to 9V. (The set voltage must not be higher than that of your electronic products)
3. Connect the correct adapter tip and make sure that it's firmly attached to the dc input port of your device.
