Replacement AC adapter for Hitachi and MSI laptops

This 19V 4.74A 90W AC/DC adapter replaces the original charger for Hitachi CML200UXW monitors and MSI Megabook AE1900, AE2010 and MS-M660 notebooks. It matches the factory voltage and current ratings so the connected device receives the correct power. The unit is supplied new and carries FCC, CE and RoHS certifications. Compatibility extends to several legacy Toshiba and MSI part numbers including PA-1900-04 and MS1421.

World-wide input with multiple safety protections

The adapter accepts 100-240VAC at 50/60Hz for use across different mains supplies. Built-in safeguards include over-current protection, over-voltage protection, total power protection and short-circuit protection. A smart chip provides overheating protection while isolation materials reduce interference. These features help maintain stable output during normal charging sessions.

10 ft power cord and OEM-grade construction

A 10 ft total cord length gives flexibility when positioning the laptop or monitor relative to a wall outlet. The housing uses high-quality wires and components tested under strict quality-control standards. The adapter is designed as a direct OEM-compatible replacement, meaning the connector fits the listed models without adapters or modifications. Buyers needing a different voltage, a higher wattage unit or a USB-C power delivery solution will not be served by this model.

Questions about this item

How do I install the WAWEIS 19V 4.74A 90W AC adapter and what step is often missed?

Connect the DC plug to the laptop first, then plug the AC cord into a 100-240VAC 50/60Hz outlet; the step often missed is ensuring the DC connector is fully seated before powering on the mains.

What maintenance or replacement will the WAWEIS 19V 4.74A 90W adapter need later?

The 10 ft power cord and DC cable should be inspected periodically for wear or damage; replace the unit if the smart chip overheating protection activates repeatedly or if output becomes unstable.

What limit appears first on the WAWEIS 19V 4.74A 90W adapter under sustained load?

The 90W total power protection and over-current protection thresholds are the first limits reached during continuous high-draw operation, causing the adapter to shut down until the load drops.
