It is pretty much pointless to have a smartphone or tablet with absolutely zero energy. Maybe it ran out of
power because of that faulty charging cable you plugged to the device, the moment you plugged it in, you
had to twist it, place it at an angle and see if it charges. But with the Remax 4 Port USB Hub, those days
are over. The name is enough to tell you how many mobile devices you can keep plugged into a wall socket.
