Answer:please dont charge like this because 2 usb output charge for other mobile    together、will give up tp 20W、that means up to 5V\/4A、quick charge 2.0 already takes    18W、that will makes another usb output only deliver 5V\/0.4Notice: if charge for device with quick charge 2.0、please dont charge for    other device at the same time
