Astrum CL520 · Replacement adapter reference
The Astrum CL520 is a 90 W replacement laptop adapter whose current manufacturer reference specifies 19 V DC, 4.74 A and a 7.4 × 5.0 mm connector. This differs from the listing title and main photograph, which indicate a 4.5 × 3.0 mm blue tip. Confirm the supplied adapter identity before selecting it for a notebook.
Identify the supplied model
The manufacturer’s CL520 specifications describe a 7.4 × 5.0 mm big-pin connector. This differs from the blue-tip 4.5 × 3.0 mm catalogue title and main photograph. Confirm the actual connector before ordering; a similar brand or wattage does not make the tips interchangeable.
A complete compatibility check
Compare the laptop’s original power-adapter requirements with the supplied unit’s output label and connector. Voltage, current or power requirement, polarity, connector geometry and any identification pin all matter. No exact supported-notebook matrix or output-polarity specification was established in the checked references.
Manufacturer design references
Astrum describes smart IC control, fluctuation absorption technology and a 94 V-0 material reference for this adapter family. These are manufacturer statements, not an independent safety certification or a guarantee against every electrical fault. Do not treat the charger as universal across HP notebooks.
Check the complete package
The manufacturer lists one CL520 laptop charger in the box. Its technical dimensions are 115 × 50 × 30 mm with an approximate 250 g weight. AC lead inclusion, cable lengths and country-plug configuration are not established by the checked package information.
Identity needs confirmation: the commercial blue-tip 4.5 × 3.0 mm title/main image conflict with the manufacturer CL520 7.4 × 5.0 mm reference. Do not rely on a brand-name or tip-colour match. Confirm the supplied label, polarity and notebook requirements.
