Abstract: A device for jump starting a vehicle with a depleted vehicle battery includes a power supply, a detecting unit, a microcontroller unit (MCU), and two output ports. At least one of the at least one of the two output ports may include a clamp. The detecting unit may be configured to detect a signal indicative of an open/closed state of the clamp. The microcontroller unit (MCU) may be configured to cut off an electrical connection of the clamp with a power supply of a booster basing on the detected signal indicative of the closed state of the clamp.
