Compatible replacement adapter

This 65 W AC adapter is built as a direct replacement for the HP 27EA 27-inch monitor. It delivers the required 19 V at 3.42 A so the display receives the exact power it was designed for. A 2.5 ft US power cord is included in the box. The unit is new and matches OEM specifications.

Input voltage and connector limits

The adapter accepts a wide AC input range of 100 to 240 V at 50 to 60 Hz, making it usable on mains supplies worldwide. Output is fixed at 19 V DC with a maximum current of 3.42 A, so it cannot power devices that need a different voltage or higher amperage. The barrel tip size must match the monitor's DC jack exactly.

Checks before ordering

Verify that the monitor's original power brick lists 19 V and 3.42 A on its label. Confirm the DC plug dimensions are identical to the original connector. Ensure the wall outlet can accept the supplied three-prong US power cord or that a suitable cable is available.
