120 W USB-C dock power adapter

This 120 W adapter supplies 19.5 V at 6.15 A to HP USB-C Dock G5 and G2 stations. It accepts 100-240 V input at 1.7 A, 50/60 Hz for worldwide use. The blue-tip barrel connector measures 4.5 mm by 3.0 mm and fits the listed dock models. It replaces HP part numbers 710415-001 and L41856-001.

Connector size prevents mismatched docks

The 4.5 mm by 3.0 mm tip is not compatible with the larger 7.4 mm by 5.0 mm barrel found on some HP chargers. Buyers must verify the dock's socket before ordering. The adapter also works with 90 W docks that use the same 19.5 V blue-tip connector. No extra cables or software are included.

Simple plug-in replacement for supported docks

Installation is a direct swap: connect the barrel tip to the dock and the IEC lead to mains power. The main risk is ordering the wrong tip size; the 4.5 mm connector will not seat in a 7.4 mm port. No driver installation or configuration is required for the supported HP dock models.

Questions about this item

Does the 4.5 mm × 3.0 mm blue-tip connector wear out and need replacement?

The 4.5 mm × 3.0 mm blue-tip connector is a fixed part of the 120 W adapter cable; if the tip or cable is damaged the whole unit is replaced, no separate tip is sold.

What limits continuous output at the full 120 W rating?

The adapter is rated for 19.5 V 6.15 A 120 W maximum output; sustained loads at that level are constrained by its internal thermal design and the 100–240 V 1.7 A input capability.

How hot or noisy does the brick get when powering a dock all day?

The power supply has no fan; it dissipates heat through its sealed enclosure, so it runs silently and warms to a typical external temperature for a 120 W class adapter under continuous load.
