The new power supply is smaller than that of Samsung and the cables appear to be thinner and more rigid. Also the connector to the laptop is no longer so fat. The power consumption is slightly larger than the previous volume of data. (1.4A to 1.6A) When product is a velcro added, with which one can tie the cord quickly.
In operation, there have been no problems, even the one and unplugging when the laptop is working properly. But I notice that the adapter is very warm. Usually not a good property, but I suppose that the manufacturer is providing a normal operating temperature and it also guaranteed.
Whether the device has the same service life as an original accessory to be seen. But even if not, the price would still justify a second purchase!
Addendum 7:01:10:
Have found that my touchpad reacts sensitively since the new power supply. Sometimes such extreme that without a control mouse is unreasonable. Have test with old PSU done so was not a problem. 1-star deduction (with USB mouse is still properly)
