Abstract
A hand held, portable jump starter device includes a housing having a multi-cell rechargeable battery, a USB input port for receiving a charging current to recharge the multi-cell rechargeable battery, and an output port for providing jump starting current to an external vehicle; a USB charge circuit including a DC-to-DC converter circuit for upconverting an input voltage on the USB input port to a higher charging voltage for recharging the multi-cell rechargeable battery; a pair of series connected transistor devices for controlling current flow into and out of the multi-cell rechargeable battery; a control circuit for detecting the voltage of the multi-cell rechargeable battery and configured to turn off the USB charge circuit to prevent over charging of the multi-cell rechargeable battery if the detected voltage exceeds a threshold value; and a battery charge controller configured to prevent over discharging of the multi-cell rechargeable battery.
