USB-C to 4.5 mm charging adapter with power display

This adapter converts a female USB-C input into a male 4.5 x 3.0 mm DC barrel plug for compatible HP laptops. It includes an integrated wattage display so the user can monitor real-time power delivery. The unit supports 19 V at 5 A for up to 100 W of Power Delivery charging.

Thermals noise and power draw in normal use

The adapter operates passively with no fan or moving parts, producing no audible noise during charging. Power draw is determined by the connected USB-C charger and the laptop's negotiated PD profile up to 100 W. Heat generation remains low thanks to the smart PD and E-Mark chip regulating current flow.

Replaces a lost or damaged proprietary barrel

This adapter lets owners of supported HP Zbook, EliteBook, Pavilion, Spectre, Envy, Stream and ProBook models use a standard USB-C PD charger instead of the original barrel supply. The jump is worth it when the original charger is unavailable and a 65 W or higher 20 V USB-C source is already owned. It is not for laptops requiring a different barrel size or voltage.

Questions about this item

How do I connect this adapter to my HP laptop and USB-C charger, and what step is often missed?

Plug the male 4.5 x 3.0mm DC jack into the laptop and a USB-C PD charger into the female port; the step often missed is confirming the charger outputs 20V at 3.25A or 5A, otherwise the adapter will not deliver power.

What part of this adapter is most likely to need replacement after extended use?

The 4.5 x 3.0mm DC plug end sees repeated insertion and cable strain, so its centre pin or barrel contact can wear out before the USB-C port or the display electronics.

At what power level does the adapter hit its hard limit during continuous charging?

The adapter is rated for 100W maximum via 20V at 5A; sustained loads above that will trigger its protection or overheat the converter.
