280W Thunderbolt Dock Adapter

This Vszerda power adapter delivers 20V at 14A for 280W total output. It fits HP Thunderbolt Dock 280W G4 units and compatible Z2 Mini G5 and G9 workstations. The 7.4×5.0mm barrel connector matches the original HP M52952-001 and M52947-003 part numbers. Buyers needing a different connector size or voltage should verify their dock specifications first.

Sustained 280W Delivery

The unit accepts 100-240V input at 50-60Hz for worldwide mains compatibility. It is rated to supply the full 280W continuously while the dock powers attached peripherals and charges the host system. Thermal design supports steady operation during extended workstation sessions. The package includes a US power cord for immediate desktop use.

7.4×5.0mm Connector Constraint

The fixed 7.4×5.0mm barrel limits compatibility to HP devices listed in the supplier data such as EliteBook 860 16 inch G10 and ZBook Fury 16 G10 models. Systems requiring a different pin diameter or centre-positive arrangement cannot use this adapter. Thunderbolt docks with higher or lower wattage ratings need their own matched power supply.
