Dell D620 laptop power adapter 90W and 65W What is the difference
To see the models, some models are relatively high configuration, you need to use the 90W adapter.
Note that the 90W adapter can be used on a 60W machine. The 60W adapter can not be used on the 90W machine.

Hello,
Look at models, some models configuration is relatively high, you need to use the 90W adapter. Note that the 90W adapter can be used on a 60W machine. The 60W adapter can not be used on the 90W machine.
90W than the power of 65W to be larger, or depends on your machine's power consumption is how much to choose the adapter.
Look at your computer's bottom shell, the above will write the input voltage and current, the two values multiplied by your machine's power consumption.
19V 3.42A is 65W
19V 4.74A is 90W.
Of course, if your battery is an enhanced version of the 9-cell battery, it is recommended to use the 90W power supply.
The greater the power certainly the better, but the adapter will be more expensive, and the power output power is how much you use the machine on the number of input, if the 65W machine selection 90W power, of course, will not have any problems, just a little waste The But on the contrary, 90W machines use 65W power supply, will be a big problem, ranging from burning the adapter, while the machine board is burned down!
