40 W AC Adapter for Samsung NP740U3E Series

This 40 W AC adapter supplies power to Samsung NP740U3E series laptops. It accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz. The unit includes a 10 ft power cord for flexible placement. It is built with new components and carries FCC, CE and RoHS certifications.

Capacity and headroom for daily charging

The adapter delivers 40 W, matching the original charger specification for the listed models. It comfortably handles normal operation and battery charging for the NP740U3E series. Protection circuits guard against over current, over voltage, short circuit and total power faults. The 10 ft cord gives reach without needing an extension lead.

Replaces a lost or damaged original charger

This unit replaces the factory power supply when the original is lost, damaged or worn out. The jump is worth it if your existing adapter shows frayed cables, intermittent charging or no output. It is not for buyers who need a higher wattage unit for a different laptop model or a multi-voltage travel kit with interchangeable tips.

Questions about this item

Will the 10 ft cord reach a wall socket while I keep using my existing Samsung NP740U3E laptop on a desk?

The adapter includes a total 10 ft power cord, giving enough length to connect from a wall outlet to a desk without moving the laptop.

How can I confirm the 40 W adapter is delivering power correctly after I plug it in?

The laptop charging indicator will light up and the battery icon will show charging, confirming the 100‑240 VAC input and 40 W output are working.

Does the box contain only the 40 W adapter and 10 ft cord, or do I need to buy a separate AC plug?
