65 W AC adapter for Compaq Presario

This 65 W AC adapter supplies 18.5 V at 3.5 A for a range of Compaq Presario laptops including the CQ40, CQ45, CQ50, CQ56, CQ60, CQ61 and CQ70 families. It replaces part numbers such as ED494AA#ABA, 391172-001 and PA-1650-02HC and ships with a mains power cord. The unit is a brand-new replacement charger for everyday use.

Check voltage, amperage and connector size

Before ordering, confirm that your original adapter lists an output of 18.5 V and 3.5 A and that the barrel connector measures 7.4 mm outer diameter by 5.0 mm inner diameter. The supplier notes that only an exact match on voltage, amperage and jack dimensions guarantees compatibility. Cross-reference the part numbers on your existing brick to be certain.

Fits Presario CQ40 through CQ70 series

The adapter plugs directly into the laptop’s DC-in jack and draws 100-240 V AC from a wall outlet, so no extra power hardware is required. It frees you from a faulty or lost original charger and restores charging and operation for the listed Presario models. Buyers needing a different voltage, a higher wattage or an alternative connector diameter should look elsewhere.

Questions about this item

Does the adapter come with the mains power cord or do I need to buy it separately?

The package includes the AC adapter and a mains power cord so no extra cable is required.

How do I know if the 7.4 mm / 5.0 mm connector fits my Presario model?

Check that your original charger lists 18.5 V 3.5 A and uses the same 7.4 mm outer / 5.0 mm inner barrel size; the part numbers ED494AA#ABA, 391172-001, 384019-003, PA-1650-02HC, 384019-001, 463958-001 and 463552-001 are also direct matches.

Will the 65 W rating actually run and charge a CQ60 under load?

Yes, 18.5 V at 3.5 A delivers 65 W which matches the factory specification for the listed Presario CQ40, CQ50, CQ60 and CQ70 series so the laptop will operate and charge normally.
