Samsung laptop power supply 40W, 19V, 2.1A, 3.0/1.1 (A13-040N2A / A40277)

The original power supply unit for the laptop is an intelligent AC adapter that will provide power to your assistant from the power grid, as well as reliably protect it from surges and voltage drops even during lightning strikes. Only the original power supply can guarantee the "correct" process of charging the battery in your laptop and, thanks to this, will significantly extend its service life. Thanks to its compact size, it will not take up much space on your desktop and will fit comfortably in your laptop bag. It does not emit extraneous sounds during operation and is distinguished by the increased quality of the cable.

When choosing a power supply unit for your laptop, pay attention to its power parameters and connector type. The power of the selected power supply must not be lower than the power of the power supply with which your laptop was equipped. Otherwise, the adapter will heat up very much during operation, will not be able to correctly provide power to the nodes of your device and may fail very quickly.

Samsung has also come up with a new type of connector for its ultrabook models. This adapter is intended for Samsung ultrabooks, in particular for the Chromebook line.
