HP 45W Smart AC Adapter

The HP H6Y88AA#ABA is a 45W Smart AC Adapter designed to power compatible HP laptops and tablets. It delivers 45 watts of output power with an 8 A current rating. The unit weighs 1.14 units and features a black finish. It serves as a replacement or spare charger for supported devices.

For users needing a 45W replacement

This adapter suits owners of HP devices that require a 45W input and accept the supplied connector sizes. It is not for buyers who need a higher wattage unit for larger laptops or workstations. Users with devices that only charge via USB-C Power Delivery without barrel connector support should look elsewhere.

Includes 4.5 mm and 7.4 mm connectors

The package provides a 4.5 mm connector for newer, smaller form factors and a 7.4 mm connector cable for legacy platforms. This dual-connector approach enables charging across current and older HP hardware generations. The included cable extends compatibility without requiring separate accessory purchases.
