The present invention relates to a portable low-frequency electrotherapy apparatus comprising a main body which comprises a universal serial bus (USB) port, a charging part electrically connected to a power pin of the USB port to receive a charging voltage from the power pin of the USB port and a low-frequency signal generator electrically connected to a data pin of the USB port to supply a low-frequency signal through the data pin of the USB port a low-frequency signal cable which comprises a low-frequency electrode connector at one end of the low-frequency signal cable to be connected to/disconnected from the USB port and electrically connected to the data pin of the USB port and an electrode pad at the other end to transmit a low-frequency signal to a human body and a power cable which comprises a power supply connector at one end of the power cable to be connected to/disconnected from the USB port and electrically connected to the power pin of the USB port, and a source connector at the other end to be electrically connected to an external power supply device. Accordingly, the low-frequency electrotherapy apparatus according to the present invention has a physical configuration which prevents a user from conducting charging a battery and an electrotherapy at the same time and prevents any accident which may occur when the charging and the electrotherapy are conducted at the same time. Also, only one port is jointly used for conducting the electrotherapy and charging the battery, and thus a charging battery is not additionally needed. Accordingly, the low-frequency electrotherapy apparatus may be small in size and flexible in design, thereby increasing user’s satisfaction for the design and improving product competitiveness.本發明涉及一種可擕式低頻電療設備,包括:主體,包括USB埠、電連接到USB埠的電源引腳以接收充電電壓的充電部分、和電連接到USB埠的資料引腳以提供低頻信號的低頻信號生成器;低頻信號電纜,包括在其一端處的低頻電極連接器,該低頻電極連接器將被連接到USB埠並被電連接到USB埠的資料引腳,或將被從USB埠斷開連接,該低頻信號電纜還包括在其另一端處的電極墊;以及電源電纜,包括在其一端處的供電連接器,該供電連接器將被連接到USB埠並被電連接到USB埠的電源引腳,或將被從USB埠斷開連接,該電
