Questions about this item

What connector size does the adapter use for HP DV5121 and DV5122 models?

The DC plug has a 1.7 mm internal diameter and 4.8 mm external diameter, matching the barrel jack on those HP laptops.

How do I connect the adapter to mains power and what mistake should I avoid?

Plug the supplied AC cord into the adapter's IEC inlet, then into a 100-240 V 50-60 Hz outlet; the common error is inserting the DC plug upside down — align the centre pin before pushing.
