Seems to work OK. I have had it a couple of months with no problems.
I am able to use it more that four hours without re-charging in performance mode.
At first i was unsure if this would work properly for my computer or not but when I received it I was over joyed because it works very well. It definitely gets the job done of charging my computer and it seems to charge it faster than my old one. I strongly suggest this charger.
It works and has continued to work for well over a year which is better than the factory model did. No complaints here.
