Compatible Charger for Samsung XE303C12

This 40W AC adapter delivers 12V at 3.33A through a 2.5x0.7mm connector for the Samsung Chromebook XE303C12. It replaces part numbers A12-040N1A and BA44-00286A and includes a 2-prong US power cord. The unit is CE and RoHS certified for safe operation.

Input Range and Connector Fit

The adapter accepts AC 100-240V at 50/60 Hz, making it suitable for international voltage standards with the correct cord. Compatibility depends entirely on matching the output voltage, amperage, and the 2.5x0.7mm tip diameter to the original charger specifications. The supplier notes it is not compatible with Samsung ATIV models XE500C21, XE550C22, or XE700T1A.

Decisive Specification: 2.5x0.7mm Tip

The connector tip diameter of 2.5x0.7mm is the single specification that determines whether this adapter fits the device. Buyers who need a different barrel size or a higher wattage output for another laptop model cannot use this unit. Verify the original charger's jack dimensions before ordering.

Questions about this item

Does the 40W rating mean the adapter will charge my XE303C12 at full speed?

Yes, the 12V 3.33A output matches the original Samsung A12-040N1A specification, so the Chromebook draws its maximum supported power.

Is the 2.5x0.7mm barrel connector the only physical difference between this adapter and the ATIV models listed?

The connector size is the critical match; ATIV models XE500C21, XE550C22 and XE700T1A use a different jack and are explicitly noted as incompatible.

Can I use the included 2-prong US cord with a 3-prong cable from another charger?

Both 2-prong and 3-prong cables work interchangeably on this adapter; the supplier notes 3-prong is not inherently better and the 2-prong cord keeps the kit lighter.
