Emergency jump starter

**Working Principle** The built-in lithium battery pack inside the device delivers a high-current instantaneous strong discharge. Through the positive and negative terminal jumper cables connected in parallel to the vehicle's battery circuit, it instantly provides the peak current required by the starter motor to crank the engine. The built-in intelligent motherboard features reverse polarity protection, overcurrent protection, short circuit protection, over-temperature protection, and low battery protection. When the positive and negative clamps are connected in reverse, it automatically cuts off power to prevent damage to the device and the vehicle's electrical system. The remaining battery power can be output through an inverter or DC port to supply power to mobile phones, laptops, and in-vehicle appliances outdoors. **Application Fields** 1. **Daily Emergency for Private Cars**: When the vehicle battery is aging or the battery is drained due to forgetting to turn off the lights, it can be used for jump-starting on the spot. 2. **Freight and Construction Vehicles**: Emergency jump-starting for heavy machinery such as trucks, excavators, and tractors when the battery is drained in the field. 3. **Outdoor Self-Driving and Camping**: Serves as a portable power bank to charge digital devices, car refrigerators, and small appliances. 4. **Emergency Rescue Scenarios**: For vehicles that break down in the wild and cannot borrow power nearby, it can independently start the faulty vehicle without the assistance of other vehicles. 5. **Night Emergency Lighting**: Comes with a high-intensity flashlight and SOS strobe warning light, which can be used for road hazard warning and temporary lighting.
