A vehicle battery jump starter that is powered by a removable and rechargeable battery pack, such as a battery pack used with various hand-held power tools. The battery pack removably connects to a vehicle battery jump starter and can be selectively used to charge a power boost module within the vehicle battery jump starter. The power boost module includes, for example, a plurality of supercapacitors or lithium polymer battery cells. The power boost module in combination with the battery pack 100 can be used to jump start a vehicle battery.

A cable connector, a cable clamp, and a method for detecting bridging of car batteries. The cable connector includes a housing and a wiring circuit, wherein the wiring circuit is arranged in the housing and includes a first wiring terminal, a second wiring terminal, and a detection module and voltage absorption module electrically connected between the first wiring terminal and the second wiring terminal, and a voltage absorption module. The voltage absorption module includes a piezoresistor bridged between the first wiring terminal and the second wiring terminal. The detection module includes a first switch circuit and a second switch circuit which are oppositely bridged between the first wiring terminal and the second wiring terminal to be alternatively turned on, wherein the first switch circuit includes a first illumination unit, and the second switch circuit includes a second illumination unit.

A motor starting assembly for starting a pull start motor includes a cup that is attachable to a flywheel of a pull start motor. A cylinder is insertable into the cup and the cylinder engages the cup when the cylinder is rotated in a first direction. In this way the cylinder can rotate the crankshaft of the pull start motor for starting the pull start motor. The cylinder disengages the cup when the when the rotational speed of the cup exceeds the rotational speed of the cylinder. In this way the cylinder facilitate the pull start motor to run without rotating the cylinder. An adapter is releasably attachable to the cylinder and a power drill thereby facilitating the power drill to rotate the cylinder when the power drill is turned on for starting the pull start motor.

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.

A starter box for small scale fuel powered vehicles includes a rigid container with two sets of mounting hardware on the top surface of the container. The mounting hardware engages suspension components of the vehicle. The starter box includes a drive wheel assembly connected to a brushless motor. The assembly includes a drive wheel with a frictional perimeter surface. The drive wheel extends partially through an opening in the top surface to engage a flywheel of the vehicle. Both sets of mounting hardware are horizontally movable to adapt to different vehicles. One set of mounting hardware is spring loaded and moves vertically when the vehicle is pressed downwardly to engage the drive wheel and a switch connecting the motor to a battery through an electronic speed control (ESC). The ESC is programmable to control the motor speed, acceleration, and latency of engagement while monitory the charge level of the battery.
