Edit (18/12/13): I went on a trip with my pc samsung N150 and charger, and surprise! He no longer works ... So more computer once the dead battery! I do not often use it yet. It is just when I'm traveling. At first it working properly. Everything was going well, but then, nothing. I re-tested the charger at home, and still nothing. So life of three months or less ... :(
If we could replace me, it'd be great! But I do not know if there is a guarantee on the charger ...
(19/10/13) Product perfectly compatible with my samsung N150 computer. The charger is small and not at all cumbersome. I did not notice any overheating.
