This 135W AC adapter from Zell Electronics replaces the original power supply for compatible HP Compaq Elite and DC series ultra-slim desktops as well as NC, NX and NW business notebooks.

The adapter matches a long list of HP part numbers including 592491-001 HSTNN-HA01 HP-OW135F13LF SE 647982-002 and PA-1131-08H. It is a direct substitute when the original 135W brick has failed or been lost. The upgrade is worth it only if your device requires exactly 19.5V 7.1A and the 7.4 x 5.0mm plug.

Verify Plug Size Voltage

Confirm that the original adapter shows 19.5V output 7.1A current and a 7.4 x 5.0mm barrel connector with centre-positive polarity. Check the label on the HP device or the old power supply for these exact figures. Do not use this unit if the required voltage current or connector dimensions differ.
