Functional Details
- Due to the large capacitance of our power adapter, it is normal for the screen numbers to flash for about a minute after the power is turned off or the AC plug is unplugged when the device is not connected.
- Since ambient temperature, magnetic field, and signal noise also affect the output voltage, it is normal and acceptable for a slight change in voltage during use.
- The short black power cord is a reverse polarity converter, not an extension wire. It is used to reverse the original polarity of the power supply output port. Please confirm the polarity of your device’s power port before use. If the positive and negative poles are reversed, it may cause an issue with your device.

The switching power supply can be for 24V 5050 3528 LED strips lights, LCD Monitors, 3D printers, Switches, LED Driver, car subwoofer amps, audio amplifiers, RC LiPo chargers, computer projects, wireless routers, ITX DC power, webcam router, CCTV camera, massage gun, external speaker, Christmas light decoration, radio, games consoles, speaker and other 3V~24V devices. Noted: Indoor use only!
Usage Precautions and Warnings:
- Please check your devices' voltage, current, and charging interface size before using them.
- Do not expose the power supply to moisture or extreme temperatures.
- Keep the power supply away from children and pets.
- It is normal for the temperature of the universal adapter to increase during powering of the devices.
-Note: This power adapter is not a charger,It is a power supply,it allows to power devices with batteries, but it cannot store power for batteries devie.Because it is not set to the corresponding instructions. This is the difference between a power supply and a charger.
How to Use the Power Adapter Correctly:
- Insert the Plug: Insert the plug of your choice into the output port of the adapter, ensuring a secure connection.
- Connect to Power: Plug the AC adapter into the power outlet. Please note that even after inserting it into the power outlet, the device will not immediately start.
- Power On: Rotate the power switch on the adapter to activate it. Please be aware that upon activating the power, you may hear a slight "click" sound. This indicates that the device has truly powered on. Likewise, when turning off the power, you will hear the same sound, signifying that the device has completely shut down.
- Adjust the Output Voltage: If necessary, use the voltage adjustment knob on the adapter to set the output voltage to match the requirements of your device. When adjusting the voltage, observe the voltage display on the adapter's screen to ensure it aligns with your device's specifications.
- Connect the Device: Insert the DC plug of the adapter into the power port of your device, ensuring a secure connection.
- Use the Device: Your device should now operate correctly. After usage, please remember to power off the device and rotate the adapter's power switch to the "Off" position.
- Remove the Plug and Disconnect Power: When you no longer require the adapter, unplug the plug and disconnect the AC adapter from the power source. If the adapter is not in use for an extended period, it's advisable to disconnect it from the power source.
-Be sure to power on the power supply first and set it to the appropriate voltage before connecting it to your device.
