Target device and users

This AC adapter replaces the HP Compaq HSTNN-Q74C power supply for notebook PCs. It suits owners of that specific laptop who need a new mains charger. Buyers whose laptops require a different connector or voltage cannot use this unit.

Critical specification

The adapter accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz, matching international mains standards. This single electrical rating decides whether the charger will operate safely on the user's local power grid.

Installation and common issues

Connection is straightforward: plug the detachable mains cord into the adapter, then connect the DC plug to the laptop. The total cord length reaches 10 ft, giving flexible placement. Problems usually arise if the laptop's required tip polarity or output wattage differs from the original HSTNN-Q74C specification.

Questions about this item

What does the 10 ft cord length mean once the adapter is on my desk?

The 10 ft total cord length gives plenty of reach from a wall socket to a laptop on a desk or table without stretching the cable.

What does the 100-240 V 50/60 Hz input cover in practice?

The wide-range input works on mains voltages from 100 V to 240 V at either 50 Hz or 60 Hz, so the same adapter can be used worldwide with only a plug adapter.

What does the adapter need to fit the HP Compaq HSTNN-Q74C?

It is built as a direct replacement for the HSTNN-Q74C model, so the output connector and voltage match the original laptop requirement.
