Product Identity

The Hadepa A1800 is a 45W AC adapter built for HP laptops that require a 19.5V 2.31A supply through a 4.5 x 3.0mm blue tip connector. It replaces part numbers such as 741727-001, L25296-001 and 213349-109 across Pavilion x360, Envy x360, Spectre x360, Stream and standard Notebook models.

Sustained Output

The unit delivers a continuous 45W at 19.5V 2.31A from a 100-240V 50-60Hz input rated at 1.2A. It is not a 65W adapter and will not meet the demand of laptops that require higher wattage. The blue tip with a 90-degree angle must match the original charger exactly for correct fit.

Thermals and Power Draw

Normal operation stays within the stated 45W ceiling, so heat output remains proportional to that load. The package includes the power adapter and a detachable AC cord. Buyers needing more than 45W or a different connector size should select another model.

Questions about this item

Does the 45W Hadepa A1800 run hot or make noise when powering a laptop all day?

The adapter delivers 19.5V at 2.31A with no fan, so it stays silent; normal warmth is expected under continuous load.

What must I already have for the 4.5 x 3.0 mm blue tip connector to work?

Your laptop needs a matching 4.5 mm by 3.0 mm blue tip DC jack and a standard C7 figure-eight mains lead for the AC side.

Will this 45W charger work alongside my older 65W HP brick on the same Spectre x360?

The 45W unit supplies less current than a 65W brick, so the laptop will charge more slowly or only maintain battery while in use.
