Is it safe to use a universal charger with my laptop?

[davidsaberxs158602df]

Hi all, this is my first post I just purchased MSI KATANA GF76 11UEK-050FR and I'm happy with it. I need a second charger for home use.
here's a pic of the laptop's charger.
So I'm wondering if I should buy exactly the same charger from an online store? Or is it safe to purchase a cheaper , universal one?
Thanks
David

One that puts out the same DC output or slightly less should work fine. That's been my experience with such things.

OK thanks. So I should look for a charger with this output: 20 V, 9A, 180W ?

Yes

Thanks inf, I ended up ordering the same charger just as in your link. But I found it very expensive though.
