A wireless charger authentication system includes an electronic device and a wireless charger. The electronic device includes an emitting module configured for producing an unauthenticated signal and a modulating module configured for modulating the unauthenticated signal into a high-frequency signal. The wireless charger includes a source signal produced by a power supply, a mixing module, an analyzing module, a comparing module and a triggering module. The mixing module is configured for mixing the high-frequency signal and the source signal to get a recognized signal. The analyzing module is configured for analyzing the parameters of the recognized signal. The comparing module predetermines a number of preset parameter values and is configured for comparing the parameters with the preset parameter values. The triggering module is configured for triggering the wireless charger to charge the electronic device if the parameters of the recognized signal are substantially equal to the preset parameter values.
