AC 100 - 240V, 50/60Hz,Output:5V 4A,as amperage isnt forced.
If your previous Adaptor was less than 4A then this will be a perfect replacement as amperage is NOT Forced)
This Adapter is for Low Volts DC5V Single colour or DC5V RGB LED strip lights.
And easy to connect the wires and work well.
Low fever & No Noise | Full Wattage 20 W | Long Lifespan.
>>The notebook Power adapter is actually a high-precision, high-efficiency switching-type regulated power supply.
>>Its function is to convert 220V AC mains power into low-voltage DC power to provide stable power for the normal operation of Laptops.
>>The notebook power adapter is made up of two parts connected, one side is the power adapter, the other side is the power cord and the socket for inserting the notebook. When the power adapter part fails, sometimes we can just replace that part. No need to change the connection hole here.
>>Since the inside of the power adapter is a switching power supply that works under high voltage and high current, the work load is relatively heavy, and it is a fully
>>There is no heat dissipation hole on the shell and no internal fan to assist heat dissipation. Therefore, the power adapter is working The internal temperature is high.
>>Especially in the hot summer,you can feel hot to touch the surface with your hands, and the internal temperature is higher.
>>Therefore, it must be properly maintained and maintained during daily office and entertainment.
>>When using the notebook in a high temperature environment, the power adapter should be placed in a place that is not exposed to direct sunlight and ventilated.
>>Do not place the power adapter near the cooling air outlet of the notebook, otherwise not only the heat of the power adapter will not be dissipated, but also To absorb some heat.
>>In the hot summer we can put the power adapter on its side to increase the contact area between the adapter and the air, so that the heat of the adapter can be better dissipated.
