The top connecto on the USB board is the input.
The left of the four pins (as it is in the photo) is the +5V one, the right of the four is the 0V side. The middle two are the computer data connections.

If you are trying to make a multi-way charger, I do not know how well that will work.

It looks like a USB switch module, intended to run from a normal USB socket on a computer. Those are only rated at half an amp (500mA) so that, or not much more, could be all you draw from the other sockets in total.

There is also a possibility that it will not do anything at all, depending on if the switch IC on it includes individual power monitoring and control; it may not provide any power without a computer feeding it.

All you can do is try it and see what happens.
