Abstract: The present disclosure provides a smart connection device, a jump starter and a battery clamp. The smart connection device includes a power connection terminal coupled to an energy storage module, a load connection terminal coupled to an external load, a switch element, a power supply loop, and a reverse connection detection module. The reverse connection detection module outputs a first control signal to the power supply loop, when the external load is reversely coupled to the load connection terminal. The power supply loop is in a disconnection state and supplies no power to the switch element when it receives the first control signal. The switch element is in an off state when it receives no power supply, to make the power connection terminal and the load connection terminal be in a disconnection state, thereby preventing the energy storage module from providing a discharge output to the external load.
