Mir is the original power supply the way the square Pinnöppel canceled that comes into the notebook. Rather unstable everything, so be careful ... And a shame that you indeed can settle the power cord, but unfortunately not the other side, then I would in fact need to buy a new cable. But well, the plug can yes the power supply is not, just as designed. One would have to criticize rather the notebook.
The price is also Just OK, so buy rating on Samsung Series 9 900X4D A02.
