Order and shipping were running as usual from easily and quickly, the power supply also made a good impression at first. Strikingly, however, was from the beginning a loud hum, like a transformer, once you get used it to recharge, and a significant heat generation. Nevertheless, it did what it should - until about the 4th or 5th application. Here was suddenly a loud bang heard, the operation lamp remained from then and the adapter stopped working. In addition, you could fry an egg on it can at this point, so hot he had become.
CONCLUSION: good idea, seemingly less good quality. I'm going to pick up the original adapter.
