PURPOSE:To prevent overdischarge and facilitate the power feed at a place far from an automobile by providing the 1st and 2nd lead wires and external feed terminals at an output unit main body and an overdischarge protection circuit inserted between them. CONSTITUTION:An output unit main body 9 is equipped with the 1st and 2nd lead wires, 16, 17 which are connected with a positive electrode 24 and a negative electrode 25 of a battery 8, and external feed terminals 11, 12. By connecting lead wires 16, 17 with electrode 24, 25 of the battery 8, direct power feed is done from the battery 8 to a load, which is not indicated in the Figure, through the output main body 9. It is not limited to be done in the vicinity of automobile, but the feed can be readily done at any arbitrary places by transferring the battery 8. If an overdischarge protection circuit 13 detects an decrease in voltage lower than a specified value of the battery 8 during the feed to a load, an alarm buzzer 14 makes a sound and lightens a light emitting diode 15 informing the user to call attention to stop the feed and to charge the storage battery 8. |
