Vehicle power device (100) supplies storage battery (21) with charging power from power conversion circuit (1a) to charge it with connector (3) attached to inlet (22) of electric vehicle (101). Stress detector (4) detects force exerted on junction (5) by tensile strength of electric cable (2). Controller (1b) is configured: to start an output operation of charging power through power conversion circuit (1a) if the detected force is below a first threshold (K1); to raise an alarm through display (1d) and sound output device (1e) if the detected force is the first threshold (K1) or more when power conversion circuit (1a) outputs the charging power; and to stop power conversion circuit (1a) outputting the charging power if the detected force is a second threshold (K2) or more when power conversion circuit (1a) outputs the charging power, where K2>K1.
