    * This power adapter has constant output voltage, but variable output current.  4.75A is just the maximum output current this power adapter can supply, it is not the actual output current.  Actual output current will be variable depends on the devices it powered.  If the output of a power supply is maintained at a constant voltage,  then the load's resistance determines the output current. It is Ohm's Law. So it will be no problem to use this power adapter to replace any 18V ~ 20V power adapter that has less than 90W output, such as 30W, 40W, 50W, 60W, 65W, 72W, 89W or any power adapter with maximum output  < =  90W
