I am using this charger with an Acer Aspire VX5-591G. All cables are the same length as the original charger and the device itself is the same size and weight. The charger appears to work the same as the original. However, the end of the DC plug that goes into the computer is weaker than my original charger. Unfortunately, this means that the plug becomes too free for charging, although it still looks like it is connected from the outside.
