Review on 40W UL Listed AC Adapter Charger for Samsung Notebook Series 9 UltraBook Ativ 900X 940X NP900 NP900X NP940 NP940X3M NP940X3L NP940X AA-PA2N40S NP540U3C PA-1400-96 Laptop Power Supply Cord by PowerSource by Benigno Reddy

This power adapter is perfect for my Samsung laptop. There is a good long cord. However, you must be careful as the tip that is inserted into the computer can bend quite easily. I tried bending it back but didn't want to press too hard as it might break. It's a little crooked but works fine. I would buy from this seller again. Update: I had to replace it because the tip was becoming too bent and loose. The seller replaces immediately free of charge. Excellent customer service. However, now 16 months later, the replacement no longer works and the wires are visible at the end of the ferrule. I just ordered another one from another company and will see how long it lasts!
