280W AC adapter for HP docks and workstations

This 280W power adapter supplies 20V at 14A through a 7.4 * 5.0 mm connector. It is built for HP Thunderbolt G4 280W Dock part numbers 4J0G4AA and 4J0G4AA#ABA, Z2 Mini G5 and G9 workstations, Z VR Backpack G1 and G2, and Envy all-in-one desktops in the 32-a0000, 32-a1000 and 34-b000 series.

Worldwide input with steady 280W delivery

The unit accepts 100-240V at 50-60Hz for global operation and maintains its full 280W output during extended sessions. Continuous 20V 14A delivery keeps docks and workstations stable under sustained load without thermal throttling or voltage sag.

Check connector size and device part number

Verify that your device uses the 7.4 * 5.0 mm barrel and matches one of the listed part numbers such as L00458-002, M52952-001, TPN-DA25 or TPN-CA25. This adapter will not fit units requiring a different connector diameter or a lower wattage rating.

Questions about this item

Does the 280W output run hot or loud when the dock is under full load all day?

The adapter delivers 20V at 14A for 280W continuous output with a 100-240V 50-60Hz input range; it has no fan, so noise is limited to faint coil whine under load, and the case warms to typical external-brick temperatures during sustained use.

What must I already own for this 7.4 * 5.0 mm connector to work?

You need an HP device that accepts a 7.4 mm by 5.0 mm barrel plug at 20V 14A — confirmed models include the Thunderbolt G4 280W Dock (4J0G4AA), Z2 Mini G5 or G9, Z VR Backpack G1 or G2, and Envy All-in-One 32-a0000, 32-a1000 or 34-b000 series.

Will this 280W brick safely replace the original supply on my older HP workstation that uses the same 7.4 * 5.0 mm jack?

Yes — if the older unit lists a 20V 14A (280W) requirement and the 7.4 mm by 5.0 mm connector, this adapter matches the voltage, amperage and polarity exactly; it also covers 100-240V 50-60Hz input for worldwide use.
