Differnt Power connector for a laptop?

[Inkz]

So I have a friend who has a Dell Inspiron 7559 and they have the same head connector but different outputs wattage. So they want to see if it works, would that damage it if they used my Alienware 17 R4's charger?

Never use a different voltage that specified on the label on the laptop.

 

You'll blow up the regulators on the board, or damage other components.

Actually idk about voltage, I meant to say output wattage. Mine is 240 and theirs is 130.

Look for where it says "OUTPUT: " on the labels.  Make sure it says the same voltage (18.1VDC, 19VDC, etc)

 

If your supply is the same voltage (probably 18.6ish), but higher wattage, then go for it.  Never go lower on wattage, but going higher is fine.

So they have same voltage but different amps?

You can use the 230W unit on the smaller laptop, but not the 130w unit on the larger laptop.

So this works?

It should, yes.  As long as your Alienware's was the 230 watt unit

240 yes
