Works perfectly for my Alienware 13r3.
Bought this for my Dell M4700, its working as expected!
Exactly like my new M15 2018 Alienware laptop.
So, I decided to look for a new one and I found it at Amazon.
As soon as it arrived I tried it and it works perfectly.
Unfortunately Amazon doesn't make it easy to figure out how to replace a part after your order is several months old.
I purchased a new cable and the adapter works fine.
If you are okay with a cheap cable and don't plan to move the adapter around then this will be a good charger alternative.
Lasted just over a month before it stopped working entirely.
Then it stopped and I had to return it.
