feature: Large-capacity batteries with low power consumption design, According to the size of the car's displacement/year/car's power loss, the emergency power supply can be fully charged once to support starting the car up to 20-30 times. Support gasoline vehicles with displacement within 12V/6.0L, and diesel vehicles with displacement within 12V/4.0L. *Does not support 24V vehicle useCharge for 4 hours, only use 0.05 kWh of electricity. Once charged, it can stand by for a long time in a fully charged state, and it can still maintain about 80% of the power for a long time. The chip is specially designed for car startup, which can withstand the strong current impact at the moment of car startup. The current is stable and the service life is long, and it does not damage the car battery and digital equipment. 4 USB digital charging ports, fast battery life for mobile phones/digital products, support QC3.0 fast charging protocol, maximum output 24W. Upgraded four strings of batteries, stronger performance, peak current 1200A. Emergency lighting, independent lighting switch, three modes of lighting, flashing, SOS signal lights, LED high-brightness lighting can be used continuously for about 72 hours when fully charged. Automatic alarm when the positive and negative levels are reversed.
