The invention discloses a portable elevator brake action reliability testing device and testing method. The device comprises a driving power supply, a high-voltage switch, a voltage detection circuit,a current detection circuit, an action detection assembly and a main control circuit. The driving power supply is connected with the high-voltage switch. The high-voltage switch is connected with a power supply control end of an elevator brake to be tested. The action detection assembly is mounted on the elevator brake to be tested. The voltage detection circuit and the current detection circuitare connected with the elevator brake to be tested. The method comprises the following steps that elevator brake parameters are input to the main control circuit, and the power-on time, the power-offtime and the testing frequency of the high-voltage switch and the working current of the elevator brake are calculated and controlled by the main control circuit; the output voltage of the driving power supply is output to the to-be-tested elevator brake to simulate the use condition; the main control circuit collects the action signal, the voltage signal and the current signal in real time; and the main control circuit calculates the reliability data of the elevator brake.
