Disclosed is a communication signal amplifier with a standby power supply. The communication signal amplifier comprises a shell internally and fixedly provided with a signal amplification module, a signal reception module, a signal transmission module and a standby power supply module, the standby power supply module is provided with an electric energy output interface electrically connected with external equipment; the input end of the signal amplification module is electrically connected with the signal reception module to amplify a wireless signal received by the signal reception module; the output end of the signal amplification module is electrically connected with the signal transmission module to transmit the amplified wireless signal outwards through the signal transmission module; and the standby power supply module is electrically connected with the controlled end of the signal amplification module to control the opening/closing of the signal amplification module. The utility model is capable of enhancing the intensity of communication signals and providing emergency electric energy for external equipment, and has the characteristics of being small in size and convenient to carry. |
