Compatible with my tablet Samsung Note 10.1, but some strange behavior

Finally a good solution to avoid plugging a multitude of specific transformers to each of my equipment.
However, sometimes there is no power on any ports, irrespective of the port used and the number of connected devices. So stick to some of the comments posted so far.
The intelligence of the electronic module is not necessarily a sufficient level to start up and adjustment of amperage distributed on ports.
Go a little effort Mr. builder, and you will have 4 or 5 stars !!!
