I did not understand the chips with 5 volts and 9 volts. The belkin adapter puts out 5 volts. The maximum power when you need the location of the phone is up to 5.1 watts. Slightly shift by half a centimeter at once 2.3 watts. Landings when charging from 5 to 4.8 volts. In general, I am satisfied, an excellent toy from the high-tech area) Pros: A very interesting gadget. I took it for the iPhone 6S in a compartment with an upvel receiver case and a belkin 2.1 amp power adapter. By the time it charges about the same, if you charge from a standard adapter through a wire. Has some cons Probably the size. I expected at least a plate with a diameter of 12-15 cm, as a result, a tiny surface of 7 cm. You also need to clearly put the phone in order to get the maximum watts, since there is an ammeter and a voltmeter.
