Is the desktop adapter's power adapter and laptop power adapter common?
As long as the interface, the output voltage and current, you can use, otherwise no
As long as the interface is completely consistent, voltage, current, etc. are also exactly the same, you can universal.
Not common, most of the notebook power supply is 18.5V, the display was only 12V, to compare the voltage, current, interface, positive and negative direction. If it can be achieved can also be common.
