This original HP power supply delivers 19.5 V at 3.33 A for a total of 65 W output. It uses a 7.4 mm barrel connector and ships with a detachable power cord. The unit is finished in black and carries part number 790946-001.

It matches the factory charger for EliteBook 820 G1, G2, G3 and EliteBook 840 G1, G2, G3 models. Buyers whose laptops require a different connector size, a higher wattage rating or a USB-C power input should look at other options.

The adapter maintains its rated 65 W during extended charging sessions without dropping voltage. A 2-pin desktop-mount design keeps the brick stable on a desk, and the included cord supports everyday transport.
