This unfortunately is not a good alternative. That it is a bit larger than the original, would get over it. In the 10 months that I already have this charger, however, it is already gone twice broken. The first time for the same reason as the Samsung PSU. The second time, a few days ago, the silver connector has come off easily from the black plastic cover due to severe overheating and got stuck in the laptop. For me unacceptable and comes for a new purchase, therefore, not in question. Only recommended for users that their charger hardly claim (back and forth, carrying, bending in and out or stuck), or some who need a quick cheap stopgap.
A star only for the low price, but satisfies the quality.
