Just want to make sure this AC adapter will fit my laptop

[Matan_2]

Hi!
I have an Asus x550c laptop.
As I mentioned I need to replace my adapter which is:
19V 65w 3.42A

The adapter I want to connect is:
19V 90w 4.74A

and the output fits of course.

I understood that what matters is the voltage, and the watts and amper are supposed to be equal or higher so I'm supposed to be in the clear, but I just wanted to make sure so nothing goes wrong.

I'll be glad if you could help

Check also the POLARITY (oftenly neglected), it should be the same as the adapter you are replacing, should look something like this:

Yes, the voltage (19V) should be the SAME while the amperes (3.42A) can be the SAME or HIGHER (never lower).

As long as the polarity isn't reversed. You should be fine.
