Rather than replace the no-name power adapter with another one, I decided to buy a genuine Dell power adapter.
Was exactly what I was looking for, exactly like the adapter that originally came with my Dell laptop.
This one fit my laptop and does the job.
Although this was purchased for someone else product appears to be a good quality product that is well made.
Works well for travel with Dell Latitude.
I bought this 2 months ago.
It suddenly stopped working.
