65 W AC adapter for Samsung Notebook 9 Pro

This 65 W AC adapter replaces the original charger for Samsung Notebook 9 Pro models NP940X5N-X01US and NP940X3M-K02US. It delivers 19 V at 3.42 A and automatically adjusts to 40 W requirements at 2.1 A. The unit is built with safeguard features against incorrect voltage, short circuit and internal overheating.

Plug-in replacement with worldwide input

Installation is a simple plug-in swap: connect the barrel tip to the laptop and the IEC lead to any 100-240 VAC, 50-60 Hz mains supply. The smart chip negotiates the correct output automatically, so no driver or software setup is required. The only common issue is using a damaged or loose DC jack on the notebook, which can cause intermittent charging.

Check tip fit and power rating before ordering

Verify that your Notebook 9 Pro uses the same barrel connector and that 65 W meets or exceeds the original adapter rating printed on the laptop label. Confirm the model number matches NP940X5N-X01US or NP940X3M-K02US, as other Samsung series may use different tip sizes or voltages. The adapter carries CE, FCC and RoHS certification for regulatory compliance.

Questions about this item

How can I verify the adapter is delivering the correct 19 V 3.42 A output after plugging it in?

The charger auto-adjusts to 19 V 3.42 A (65 W) and includes a smart chip that confirms compatibility with the Notebook 9 Pro; the laptop's battery icon should show charging within seconds.

What comes in the box and do I need a separate mains lead?

The package contains the 65 W AC adapter unit with integrated safety protections; a standard C5/C6 mains cable for your local 100-240 V socket is not included and must be sourced separately.

My Notebook 9 Pro originally used a 40 W brick — should I choose the 65 W version instead?

Yes, this adapter auto-adjusts down to 19 V 2.1 A (40 W) so it safely replaces both the 65 W and 40 W originals for models NP940X5N-X01US and NP940X3M-K02US.
