Abstract
A battery charger adapted for connection to a standard 12 volt vehicle battery through a cigarette lighter socket includes a transistorized saturable-transformer DC to AC inverter and an AC to DC rectifier for generating a potential higher than the potential from said 12 volt vehicle battery. An integrated circuit pulse width modulated current control is used to control charging current flow to a second battery to be charged and to maintain charging current at a safe level.
