This charger plugged in and ran on my computer, but it isn't the same as the ASUS charger.
It will probably work fine on a standard computer, but I don't think I'd use it on a high-end computer that is under warranty in case it goes screwy and voids a warranty.
I didn't look closely, but I took a few measurements under no load.
Works just as you'd expect, came just as promised, perfect replacement after the cat chewed my charger cord.
It works fine .
Bought this as a replacement for an Asus Q504U.
It does not work with this specific model laptop.
And during those short 2 weeks, it charged very slowly.
I was able to return this, thanks to Amazon's great return policy, but it would have been nice if this thing had actually WORKED.
Save your money and buy something else.
