230W 19.5V AC adapter for HP Omen and ZBook

This 230 watt power supply delivers 19.5 volts at 11.8 amps through a 7.4mm by 5.0mm barrel connector. It fits HP Omen 17-an series laptops and ZBook 15 G2 or 17 G2 mobile workstations. The unit also powers the HP Thunderbolt Dock 230W G2 and the HP ENVY Curved 34-b000 All-in-One desktop.

Continuous 230W output with wide-range input

The adapter accepts 100 to 240 volt AC at 50 to 60 hertz, making it suitable for international mains supply. Built-in protection circuits guard against short circuit, overvoltage, overcurrent and internal overheating during sustained load. Safety compliance and quality control procedures support reliable long-term operation.

7.4mm x 5.0mm centre-positive barrel connector

This specific plug geometry is the single detail that determines physical compatibility with the listed HP models. It does not fit ZBook 15 G3 through G7 or 17 G3 through G7 units, which use a different connector. Verify the original charger tip dimensions before ordering.

Questions about this item

How much heat or noise does the 230W 19.5V adapter produce when running continuously?

The unit has no fan, so it runs silently; its safety circuitry protects against internal overheating, overcurrent and overvoltage during all-day use.

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

You need a compatible HP laptop or Thunderbolt Dock 230W G2 that accepts a 19.5V 11.8A barrel plug of that exact size.

Will this 230W supply power an older HP EliteBook 8740W alongside a newer ZBook 15 G2?

Yes — it fits the EliteBook 8740W, 8760W, 8770W and the ZBook 15 G2 and 17 G2, but it does not work with ZBook G3 through G7 models.
