PURPOSE:To prevent overdischarge and facilitate the power feed at a place far from an automobile by providing an external feed terminal at the output unit in which an overdischarge protection circuit is inserted between the terminal and the 1st and 2nd receiving members. CONSTITUTION:There is provided with output unit main bodies 9, 10 on which first and second receiving members 17, 21 to be mounted on positive and negative electrodes 14, 19 of an automobile battery 8 are formed. An output unit main body 9 is equipped with lighter sockets (external feed terminals) 11, 12. By the arrangement, direct power feed is done from the battery 8 to a load, which is not indicated in the Figure, through the main body 9. It is not limited to be done in the vicinity of automobile, because the feed can be readily done at any arbitrary places by transferring the battery 8. If an overdischarge alarm circuit 16 detects an decrease in voltage lower than a specified value of the battery 8 during the feed to a load, an alarm buzzer 24 makes a sound informing the user to call attention to stop the feed and to charge the battery 8. |
