19V AC adapter for Samsung Ultrabooks

This 19V AC adapter replaces the original charger for Samsung Series 7 Chronos NP740U3E and ATIV Book NP940X3L ultrabooks. It delivers the exact voltage the laptops require and is built as a direct replacement for the factory unit.

Questions about this item

What AC input range does the 19V adapter accept?

The adapter works with a worldwide 100-240VAC 50/60Hz supply, so it can be used on mains voltages from 100 V up to 240 V at either 50 Hz or 60 Hz.

What connector and cable length are needed to reach the laptop?

A single 10 ft power cord is integrated, ending in the barrel plug that fits the Samsung NP740U3E and NP940X3L charging ports.

How do I install the adapter and what step is often missed?

Plug the mains lead into a wall socket, then push the barrel connector firmly into the laptop until it seats; the step people skip is confirming the LED on the plug lights up to show charging has started.
