Virtually any load

Buy to replace the charger 6 of my devices and I am delighted. Apart from a slight buzzing march has no worries signal. By very careful against a power: if I put 2 tablets to load (and iPad tab S), he rowed a little at charging time. But as I plug in general all night, ca suits me. I keep even qd original charger plug into one of my catch for fast charging (even if I have only one branch unit, the charge is slower than the original charger power ... question?). it is good, not too expensive and seems pretty solid. Only negative point, the hum that can be annoying when the unit is close enough for you.
