ABSTRACT:
An emergency battery charger device is disclosed which, in its simplest form, includes a pair of cigarette lighter plugs having their negative contacts coupled together by a conductor and having their positive contacts coupled together by means of a current limiting device such as an incandescent bulb. In use, one of the plugs is plugged into the cigarette lighter socket of a vehicle having a discharged battery and the other plug is plugged into the cigarette lighter socket of a vehicle having a fully charged battery. Current will flow from the good battery and from the good battery's charging system to the bad battery through the incandescent light bulb so as to trickle charge the bad battery. The incandescent bulb serves the dual function of limiting the charging current and acting as a charging rate indicator. A shorting sleeve is also disclosed for shorting the contacts of one of the plugs so that the incandescent bulb can also be used as an emergency light.
