As far as I can judge the charger works, but it produces annoying sound in the process of charging. As I released it from a blister there was something loose in the power adapter so I had to open it. Transformer frame was loose and the general expression was that the assembler was drunk or sleepy - poor assembly quality.
The charger itself produces a sound too and has too tight sockets.
Still, it charges...yet. We'll see how long it will last.
