Replacement AC Adapter for Samsung Notebook 9 Pro

This 19V 2.1A 40W power supply replaces the original charger for Samsung Notebook 9 Pro 13 and 15 models including NP940X3N-K01US, NP940X3NI, NP940X3M, NP940X3G, NP940X3K, NP940X3L and NP940X5N. It matches the AD-4019A specification and carries FCC, CE and RoHS certifications. The unit is brand new and built with 100% new components.

Installation notes and common issues

The adapter uses a standard mains lead and a single output tip that fits the listed Samsung notebooks directly. No driver or software setup is required. The total cable length is 10 ft, giving flexibility for desk or floor routing. The only frequent problem is selecting the wrong tip size for a model not listed above; verify the exact NP number before ordering.

Deciding specification — 19V 2.1A 40W output

The critical figure is the 19V 2.1A 40W output rating, which must match the laptop's original power requirement. The wide 100-240VAC 50/60Hz input handles mains voltages worldwide. Built-in protection covers over-current, over-voltage, short-circuit and total power faults. Buyers whose device needs a different voltage or amperage cannot use this adapter.
