150W 19.5V 7.7A Charger for HP ZBook and Omen - High Power Adapter

In this review of the 150W 19.5V 7.7A Charger from NeaHao the bottom line is straightforward: this adapter is for users who need a highpower replacement or spare for HP ZBook Studio, Pavilion, OMEN and compatible mobile workstations. The reviewer found it delivers the advertised power and fast charging performance for demanding 15in and 17in laptops, and it works with several lower current models as well. The unit is not a branded OEM part, so buyers looking for factory labeling should be aware, but most users will appreciate the reliable charging and included power cord.

Key Features

• High output: The 19.5V 7.7A 150W maximum output supplies enough power for heavy GPU and CPU loads on workstation and gaming laptops.
• Wide input range: The 100-240V input lets this adapter be used internationally without a voltage converter.
• Compatibility: Works with HP ZBook Studio G3 through G8, ZBook 15/16/17 series, OMEN and Pavilion 15-17 laptops, covering many mobile workstation needs.
• Multiple supported amps: Also compatible with devices that require 19.5V at lower currents such as 6.9A, 4.5A and 4.5A variants, so it can replace several lower watt adapters.
• Connector size: Uses a 4.5mm x 3.0mm tip as shown in product images, which matches many HP power input jacks.
• Packaged ready: Includes the 150W power adapter and a 3prong AC power cord so buyers get a complete replacement set.

Who It's For

This adapter is aimed at professionals and gamers who own HP ZBook Studio, ZBook 15/16/17, or 15u/15v x360 mobile workstation models and need full 150W power to keep performance steady under load. It is especially useful as a spare charger for travel, a desk replacement, or to restore charging for laptops used for rendering, CAD, or gaming.

Users who require an original HP branded adapter for warranty or corporate procurement reasons should look elsewhere, as this is a compatible thirdparty unit. Also check the 4.5mm x 3.0mm tip size against your laptop port to ensure a correct physical fit before buying.
