85W Dell AC Adapter for HP Laptops

This Dell SK90195231 adapter delivers 85W at 20V and 11.8A for compatible HP laptops. It replaces numerous HP part numbers including 740015-001 and PA-1450-56HA. The unit is new and features a blue tip connector. It suits owners of supported HP models needing a replacement charger.

Blue Tip Connector Compatibility

The single deciding specification is the blue tip connector that fits HP laptops requiring 19.5V at 2.31A. Only models listed in the compatibility data will work with this adapter. Buyers must verify their original charger uses the identical blue tip before purchasing. Units with a different tip size or voltage will not connect or charge correctly.

Thermals and Power Draw

The adapter supplies up to 85W output while drawing power from a standard 2-pin mains cord. Normal operation stays within the rated 20V and 11.8A limits without additional cooling requirements. No fan or active cooling is present. The corded electric design keeps the brick at typical adapter temperatures during charging sessions.

Questions about this item

What does the 85W output mean for my laptop in daily use?

The adapter can supply up to 85 watts at 20 volts and 11.8 amps, so it will charge compatible laptops at their maximum supported rate and run them under load without draining the battery.

What connector standard does the blue tip use and what does it limit?

The blue tip is a proprietary HP barrel connector that fits only models designed for 19.5 volt 2.31 amp 45 watt input; it will not mate with USB-C or other barrel sizes.

What physical space and mounting does the adapter need?

The brick weighs 8.8 ounces and uses a two-pin North American plug with an attached cord, so it sits on a desk or floor near a standard wall outlet.
