Abstract: A battery clamp is provided that includes a first inner metal battery clamp member having a handle portion and a clamp portion, a second inner metal battery clamp member having a handle portion and a clamp portion, a pivot pin pivotally connecting the first inner metal battery clamp member to the second inner metal battery clamp member, a first outer insulating battery clamp member having a handle portion and a clamp portion connected to the first inner metal battery clamp, and a second outer insulating battery clamp member having a handle portion and a clamp portion connected to the second inner metal battery clamp, the first outer insulating battery clamp member or the second outer insulating battery clamp member including a protective cover section covering an end of the pivot pin.

Abstract: An electrical port device having an electrical port and a cap or cover removable connected to the electrical port having a plug. An electrical cord or cable or cable section connects the electrical port to an electrical cord or cable or cable connector or splitter into a pair of electrical cord or cable or cable sections each provided with an electrical receptacle. Further, the cap or cover and the electrical port have cooperating sealing surfaces to ensure a tight waterproof sealing when the cap or cover is installed on the electrical port to prevent water or moisture reaching the plug.

Abstract: A rechargeable battery jump starting device and a rechargeable battery assembly for use in the portable rechargeable battery jump starting device. The portable rechargeable battery jump starting device maximizes the power conducted from the rechargeable battery assembly to a battery being jump started.

Abstract: A jump starting apparatus configured for jump starting a vehicle battery includes a rechargeable battery, a first battery cable having a first battery terminal connector for connecting the jump starting apparatus to a first battery terminal of the vehicle battery, a second battery cable having a second battery terminal connector for connecting the jump starting apparatus to a second battery terminal of the vehicle battery, a first conductor bar or plate connecting a conductor of the first battery cable to a first tab or terminal of the rechargeable battery, and a safety control system or circuit configured for detecting when the jump starting apparatus is properly connected to the vehicle battery and then switching on power from the rechargeable battery to the vehicle battery only when the jump starting apparatus is properly connected to the vehicle battery.

Abstract: A rechargeable battery assembly includes a rechargeable battery having a positive terminal and a negative terminal, and a rigid electrically conductive frame electrically connected to at least one of the positive terminal or the negative terminal of the rechargeable battery. The rigid electrically conductive frame is bent along multiple axes and includes a plurality of conductive frame members that are mechanically coupled together. The rigid electrically conductive frame surrounds the rechargeable battery on at least five sides, thereby providing structural stability to the rechargeable battery assembly during storage and use.

Abstract: An apparatus for jump starting a vehicle includes a handheld booster device comprising a rechargeable battery pack, a control circuit, a power switch, and an output port, wherein the control circuit detects when it is safe to couple the handheld booster device to the vehicle's battery and connects the rechargeable battery pack to the output port thru the power switch; and a jumper cable device comprising a plug and a pair of cables integrated with the plug, the plug being configured to connect to the output port of the handheld booster device in a specific orientation.

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.

Abstract: A rechargeable battery jump starting device and a rechargeable battery assembly for use in the portable rechargeable battery jump starting device. The portable rechargeable battery jump starting device maximizes the power conducted from the rechargeable battery assembly to a battery being jump started.
