90W AC Adapter for NP-RC512 Series

This 90W AC adapter replaces the original charger for NP-RC512-A01US and NP-RC512I laptops. It supplies the rated power needed for daily operation and battery charging. The unit is new and built for direct replacement use.

Practical limits of the 90W barrel interface

The adapter delivers up to 90 watts through a barrel connector, so it cannot support devices requiring higher wattage or USB-C Power Delivery. Load should stay below 80 percent of the rated maximum for optimal longevity. Voltage must match the laptop specification exactly to avoid damage.

Replaces a lost or failing OEM charger

This part replaces a missing, damaged or worn-out factory power supply for the listed models. The jump is worth it when the original brick no longer holds a charge, shows cable wear or has been lost. It restores full charging and runtime without modification.

Questions about this item

Is the 90 W rating the right choice for my NP-RC512-A01US or NP-RC512I laptop?

Yes, this adapter is built as a direct replacement for both the NP-RC512-A01US and NP-RC512I models, so the 90 W output matches the original specification.

What does the 90 W output actually deliver when the charger is connected to my laptop?

It supplies up to 90 W of continuous power, enough to run the system and charge the battery simultaneously under normal workloads.

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

It uses the proprietary barrel connector required by the NP-RC512 series, which limits compatibility to those specific Samsung models.
