Smart AC Adapter Dongle HP Compaq 414136-001 90W – 3-Pin Smart to Legacy Power Converter – Compatible HP Notebook Power Connector

The HP 406824-001 / 414136-001 Smart Dongle Cable is a DC power converter cable designed to connect a HP 90W Smart AC Adapter (7.4×5.0mm blue pin) to older HP/Compaq laptops that use a 4.8×1.7mm small barrel connector.

This cable does not include the power adapter — it is only the short converter lead used between the charger and the laptop.
