120W 19.5V 6.15A Charger for HP USB-C Dock G5 - Reliable Replacement

In this review the 120W 19.5V 6.15A charger is evaluated as a practical replacement for HP docking stations and compatible laptops. The bottom line: it is for anyone who needs a highpower, simple swap-in adapter for HP USB-C Dock G5 models or select HP Pavilion and Omen laptops, and the single biggest reason to buy is its correct 120W output and the common 4.5mm x 3.0mm connector size that matches many HP docks. The reviewer found it performs consistently and restores full docking power without fuss.

Key Features

• 120W output: Delivers 19.5V at 6.15A to supply power-hungry docks and laptops that require a higher wattage source for charging and peripherals.
• Wide input voltage: Accepts 100-240V 1.7A 50/60Hz so it works worldwide with the correct plug or travel adapter.
• Connector size clarity: Uses a 4.5mm x 3.0mm barrel that matches the specified HP docks, reducing the risk of ordering the wrong plug size.
• Compatibility list: Notes compatibility with multiple HP USB-C Dock G5 and Universal Dock G2 part numbers, making it easy to match with existing hardware.
• Replacement fit: Intended as a direct substitute for P/N entries like 710415-001 and L41856-001, offering a practical way to replace a lost or failed factory adapter.

Who It's For

This charger is best for users who own an HP USB-C Dock G5, HP USB-C/A Universal Dock G2, or HP laptops in the Pavilion, Envy and Omen 15 series that accept a 4.5mm x 3.0mm connector and require up to 120W. IT staff and home office users who need a dependable replacement power supply to restore full docking station functionality will appreciate the straightforward match to listed part numbers.

Users who should look elsewhere are those with laptops or docks that use the larger 7.4mm x 5.0mm barrel, devices requiring USB-C PD negotiation via a USB-C plug, or models not mentioned in the compatibility list; the product is a barrelstyle charger and not a universal USB-C PD brick.

Pros & Cons

Pros

• Restores full power to compatible HP docks and laptops with the specified 120W output.
• Works on global voltages 100-240V for travel and mixed power environments.
• Clear connector size reduces wrong-fit purchases compared with ambiguous listings.

Cons

• Uses a barrel connector (4.5mm x 3.0mm) so it is not compatible with devices needing a 7.4mm x 5.0mm plug or native USB-C PD charging.
