For a long time, I wanted a similar charger for myself, it was made qualitatively, now you can charge 3 devices.

Already tried to use it in extreme conditions, well, as extreme, on the train, showed itself not very bad, the voltage itself selects for each type of device, tried different generations of phones, their charge was carried out in voltage from 0.65 to 1.3.

Unfortunately, it is not possible for me to measure how much voltage it produces on each of the ports.
