USB-C to 4.5x3.0mm blue tip PD adapter

This adapter converts a USB-C Power Delivery source into a 4.5x3.0mm blue tip DC connector for compatible HP laptops. It contains a built-in PD trigger chip that negotiates 18.5V to 20V output from a supported charger. The unit is designed for HP models that use this specific barrel size and require 65W or less power input. It provides a simple plug-and-play connection for charging.

Suits HP 4.5mm barrel users.

Buyers with HP laptops that accept a 4.5x3.0mm blue tip and run on 65W or below will find this adapter matches their charging port. It does not work with Dell models or any device requiring a different barrel diameter or tip colour. The adapter also cannot supply 5V output, so it is unsuitable for hardware that relies on lower USB-C voltages. Users needing higher wattage than 65W should look elsewhere.

Negotiates 18.5V-20V from 65W+ USB-C PD chargers

The internal PD chip requests a 18.5V to 20V fixed profile from any USB-C charger that supports Power Delivery at 65W or above. Without a compliant PD source the adapter will not deliver the required voltage. This single voltage negotiation step decides whether the connected HP laptop receives power.

Questions about this item

What USB-C charger do I need to power this adapter?

Use a USB-C wall charger with Power Delivery rated at 65W or higher; the adapter has a built-in PD inducing chip and outputs 18.5V-20V DC.

Will this adapter work with my older HP Pavilion 14-n000 that uses a 4.5mm*3.0mm blue tip?

Yes, it supports HP laptops up to 65W with the 4.5mm*3.0mm DC tip, including the Pavilion 14-n000 listed in the compatibility list.

How can I confirm the adapter is delivering the correct voltage after I plug it in?

The adapter outputs 18.5V-20V DC only (no 5V); your laptop should charge normally and show the charging indicator when connected to a compatible PD charger.
