So the price is of course top but the processing is not really good ... the plug for the power socket is only 2 pin the original power supply has NEN 3 pole ... the plug to the power supply itself lies only loosely in the power supply ... the plug which is part of the notebook is also very loosely ... who before has should operate his laptop without battery not buy this power supply as the power connection can break even with smaller movements !!! Conclusion: Cheap in every way PS have a Acer 5290g
