3~24V Adjustable Voltage
Before purchasing, check your device's label for the operating voltage. It should be between 3V and 24V, avoiding voltages below 3V or above 24V to prevent malfunctions.
Pure Copper Wire Core
The use of pure copper wire cores in our power adapters not only enhances conductivity but also ensures exceptional durability, resulting in a significantly extended lifespan for your power supply.
LED Display Voltage
The power supply features a clear LED display that shows the real-time voltage output, allowing you to monitor your device or project. Please note that due to a voltage drop of 0.5V caused by the power cable between the power block and the DC plug, the displayed voltage range is designed to be 3.5V to 24.5V.
Compatible with Most Home Appliances
- Our AC to DC power adapter is compatible with a wide range of small household electronic devices that operate within the voltage range of 3V to 24V and draw a current of less than 3A(such like 3A,2.5A,2A,1.5A.1A...). These include but are not limited to LED light strips, under-cabinet lights, humidifiers, USB fans, and various other small appliances.
- 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.
- 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.
3V~24V 3A 72W Adjustable Power Supply
How to Choose the Right Plug:
1:Check the input port size from your device's specification information
2: Measure the Inside Diameter of Your Device's Plug: Use a ruler or tape measure to accurately measure the inside diameter of your device's plug.
The Size of Plugs:
A:6.4x4.0mm+Pin,C:5.5x2.5mm,H(yellow):5.0x3.0mm+Pin,D:5.0x2.5mm,B:6.3x3.0mm,E:5.5x1.7mm,F:4.8x1.7mm,G:4.0x1.7mm,H(red):3.5x1.35mm,L:3.0x1.1mm,I:2.5x0.7mm, Micro-USB,Type-C and DC terminal connector.
The Polarity of plugs:inside"+", outside"-".
Package included:
- 1 x 72W Power Supply Adapter
- 14 x DC Tips
- 1 x Reverse Polarity Converter Cable
- 1x Instruction Manual
- 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.
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.
