120W USB-C Dock G5 Power Supply - HighOutput 19.5V 6.15A Adapter

In this review the HNHTKJ 120W AC Adapter is evaluated as a direct replacement power supply for HP docking stations and select Envy laptops. The bottom line: this adapter is for users who need a reliable, highoutput replacement capable of driving a USB-C dock or charging compatible laptops that expect a 19.5V, 6.15A feed. It earns recommendation mainly for its precise voltage rating and long cable reach, which make it an easy swap for a failed original or for running a docking station from a convenient outlet without changing desk layout.

Key Features

• Power output: The 19.5V 6.15A 120W rating supplies sufficient power for demanding USB-C docks and many Envy notebook models without throttling.
• Tip compatibility: The 4.5 x 3.0mm tip matches the connector found on HP Dock G5 and related docking stations for a direct physical fit.
• Wide compatibility: Works with Dock G5 models listed and multiple Envy M6 and M7 series machines, reducing the need to hunt for an exact OEM number.
• Global input: The AC 100-240V, 50/60Hz input supports worldwide voltages so the adapter can be used in multiple countries with the right plug.
• Long cable run: A total 10 ft of cable (6 ft charger cable plus 4 ft power cord) gives flexible placement options for docks and power outlets.
• Complete kit: The box includes the charger and a detachable power cord so the unit is ready to install immediately.

Who It's For

This adapter suits IT technicians, home office users, and anyone running an HP USB-C Dock G5 or Universal Dock G2 who needs a like-for-like replacement power supply. It is especially helpful when desk layout requires extra cable length or when an original OEM unit is unavailable.

It is less appropriate for users who require USB Power Delivery negotiation via a USB-C port for newer laptops; this model is intended as a direct power brick for specific docks and legacy Envy series laptops rather than a universal PD charger for every modern USB-C notebook.
