Alright packaging (bubble wrap envelope) and fast shipping (about 3 weeks to Belgium). The item works very good! It could hold a stable 20V output when the input changed from 4 to 25V! Could sustain 20V 3A with a 12V input just fine. Got a bit hot but nothing too major. The components inside seem to be of good quality. THE DC JACK IS 5.5x2.5 mm though, so not all "regular" adapters fit (but I suppose this is because this bigger inner pin can carry more current). The USB A 5V output seems to be limited at 3.4A. The Type-C input tries to ask for 20V. Too bad it can't display the current protocol/voltage but that's fine, the unit is very compact this way. Heat sinking is alright. You can't plug both a type A and type C connector in the outputs at the same time because they are too close together. I'm very satisfied!
very good~!
