This 40W AC adapter supplies 12V at 3.33A through a 2.5mm by 0.7mm barrel tip. It accepts 100-240V input at 50-60Hz for worldwide use. The package includes the adapter and a detachable power cord. It replaces Samsung part numbers AD-4012NHF, A12-040N1A, BA44-00286A, AA-PA3N40W and PA-1250-98.

Fits Chromebook 2, 3 and ATIV models

Owners of Samsung Chromebook 2, Chromebook 3, XE303C12, ATIV Book 9 and ATIV Smart PC models listed in the compatibility table can use this charger. Buyers with laptops that require a different voltage, amperage or connector size should look elsewhere. Units needing USB-C Power Delivery or a higher wattage rating are not supported.

2.5mm by 0.7mm barrel connector decides fit

The tip diameter of 2.5mm outer by 0.7mm inner is the single specification that determines whether this adapter will connect to your device. Verify the port on your Samsung laptop matches this exact size before ordering. A mismatch means the plug will not seat or charge correctly.
