The receiver output short-circuit current can reach 1A, the actual charging is only about 0.3, plug in the mobile phone voltage directly dropped to 3.9V, this voltage can not reach the rated voltage to charge the mobile phone, and the maximum working current of the wireless transmitter is only 600ma, smart phone charging needs more than 700ma~800ma. Therefore, the transmission power of the wireless charger is too small, and it will also make the charge not go in.
