19.5V 4.62A 90W laptop ac adapter for dell 

Dell Computer Charger 

The 90w laptop power adapter for dell with dc output 19.5V 4.62A , dc size 7.4*5.0mm suit for dell laptop. This 19.5V 4.62A 90W laptop charger Regardless of any laptop accessories , there is a certain internal resistance, so when the laptop adapter  outputs current, a voltage drop will be generated internally, which is equal to the output current times the laptop power supply  internal resistance. It causes two things. One is to generate heat, which is equal to the square of the output current multiplied by the internal resistance, so the computer charger  will heat up. The other is that the output voltage becomes the nominal voltage minus the internal voltage drop, which causes the output voltage to decrease. In general designs, after considering the heat dissipation problem, a current value is generally limited. When the output current reaches this value, the output voltage is reduced to 95% of the nominal voltage
