This 65W AC adapter supplies 18.5V at 3.5A for the listed HP laptops. It accepts 100 to 240V input at 50 or 60Hz for worldwide use. The barrel connector measures 1.7mm inner diameter and 4.8mm outer diameter. An AC power cord is included in the box.
Thermals noise and power draw

Questions about this item
How do I install the adapter, and which connector detail is often missed?
Plug the AC cord into a 100 to 240 volt 50 to 60 hertz outlet, then connect the DC barrel plug; the tip must match the 1.7 millimetre inner and 4.8 millimetre outer diameter used by the HP Zt3420ea series.
What maintenance or replacement will this adapter need over time?
The detachable AC cord can be swapped if damaged; otherwise the sealed 65 watt 18.5 volt 3.5 amp unit has no user-serviceable parts and is replaced as a whole when output drops or the connector wears.
