Target Laptop Models

This AC adapter is designed for Compaq Presario notebooks in the CQ50, CQ56, CQ57, CQ58, CQ70 and CQ71 series. It supplies the correct DC output for those specific chassis and charging circuits. Buyers who own a different Presario line or another brand will need a separate unit.

Critical Compatibility Check

The single specification that determines fit is the exact model number printed on the laptop base or the original charger label. The listing photographs show the connector tip and cable layout; these must match the old adapter precisely before ordering.

Sustained Operation Behaviour

Each unit is tested before dispatch to verify stable voltage delivery under continuous charging load. The adapter maintains consistent output during extended sessions without thermal shutdown or voltage droop that could interrupt battery charging.

Questions about this item

What does the 100 % compatibility claim mean once the adapter is installed?

The adapter is tested before shipping and designed to match the original power requirements for the listed Compaq Presario models.

Which connector standard does this adapter use and what does it limit?

It uses the barrel connector shown in the product photos, which limits use to laptops that accept that exact tip size and polarity.

What physical checks are needed to ensure the adapter fits and mounts correctly?

Compare the tip diameter, length and centre pin against your original adapter, and verify the cord length reaches your wall outlet.
