40W 12V AC adapter for Samsung Chromebooks

This 40W AC adapter delivers 12V at 3.33A through a 2.5mm outer, 0.7mm inner barrel connector. It replaces Samsung part numbers A12-040N1A, AD-4012NHF, BA44-00286A and AA-PA3N40W. The unit accepts 100-240V 50-60Hz input for worldwide use. It ships with the adapter and a detachable AC power cord.

40W output with 26W compatible mode

The adapter supplies a full 40W at 12V 3.33A for models that require the higher current. It is also compatible with devices rated for 12V 2.2A 26W, providing headroom for those lighter loads. It runs out of capacity for any system demanding more than 40W or a different voltage. Buyers needing higher wattage or a different output voltage cannot use this unit.

Fixed 2.5mm by 0.7mm barrel connector

The non-detachable DC cable ends in a 2.5mm outer diameter, 0.7mm inner diameter plug that mates directly with the listed Samsung Chromebook and ATIV Smart PC models. No alternative tips or USB-C output are provided. The package includes a standard IEC C7 figure-8 AC cord for wall connection. Users whose laptops require a different connector size or a USB-PD interface will need a different adapter.

Questions about this item

Will this 12V 3.33A adapter power my Samsung NP930X2K ATIV Book 9 alongside the original 26W charger I kept?

The adapter supplies 40W at 12V 3.33A and is listed as compatible with the NP930X2K series; it also supports 12V 2.2A 26W operation, so it can replace the original charger without needing both connected.

How can I verify the 2.5mm by 0.7mm barrel plug is delivering 12V 3.33A to my XE503C12 Chromebook after setup?

The Chromebook charging indicator should light when the barrel connector is seated; the adapter’s 100-240V 50-60Hz input range means it will operate on any mains supply without further adjustment.

Does the package include both the AC adapter and a mains cable for UK sockets, or must I buy a cord separately?

The box contains one AC adapter and one AC power cord, providing the complete connection from wall outlet to the 2.5mm 0.7mm barrel plug.
