Questions about this item

Does this adapter use a standard 18.5 V barrel connector with 4.8 mm outer and 1.7 mm inner diameter?

Yes, the DC plug measures 4.8 mm outer diameter and 1.7 mm inner diameter, matching the 18.5 V 3.5 A 65 W output specified for compatible HP models.

What physical clearance does the barrel plug need to seat properly in the laptop?

The connector requires a port that accepts a 4.8 mm external diameter and 1.7 mm internal diameter pin, so the jack opening must accommodate those dimensions for a secure fit.
