The workmanship is excellent and makes a very high-quality impression. According to the manufacturer they have an energy efficiency by over 90%, which is excellent. The different angled plug adapters also make a very robust and are polarized. I tested one for a Samsung notebook and one for an Acer notebook. The match as well as the original plug. The temperature during loading is comparable to the original power supplies.
I would not hesitate to buy it again, because my automatic voltage adjustment, the robust adapter and the flat case very much. Although there are cheaper power supplies, but this is worth the money.
