The processing of the connector works well and the load values are clearly and legibly placed on the connector. The small size (a little larger than a normal plug) it is visually pleasant.
There may be two different devices are connected. The one with a voltage of 5 V, 2.4 A and one with V 1.0 A. It is also loading on both USB ports is not warm and completely silent to my ears.
Conclusion: power from a socket, two USB connectors with different voltages and that at a reasonable price
