Abstract
A wireless charging method, a transmit end device (), and a wireless charging device () are provided. A charging process between the transmit end device () and the wireless charging device () may be a cyclic process. To be specific, the transmit end device () sends an electromagnetic wave signal to the wireless charging device () for charging. The wireless charging device () uses a part of the electromagnetic wave signal for charging, feeds back the other part of the electromagnetic wave signal to the transmit end device () for amplification, and then uses an amplified electromagnetic wave signal to charge the wireless charging device (). In this way, the transmit end device () and the wireless charging device () can reach a stable power range to perform wireless charging, so that charging performance is improved.
