An electricity feature identification device and a method thereof are provided. The device comprises a receiver, a storage, and a processor. The receiver is configured to receive an electricity signal continually. The processor is electrically connected to the storage and the receiver, and configured to sample the electricity signal to obtain a piece of testing electricity information, and store the testing electricity information in the storage. The processor is also configured to sample the electricity signal every sampling interval to individually obtain a piece of reference electricity information until the number of the reference electricity information is equal to a preset sample amount, and store the reference electricity information in the storage. Finally, the processor is configured to compute a statistical feature of the reference electricity information, and compare the testing electricity information with the statistical feature to obtain a comparison result.
