- Emergency jump starter: 1000A peak current allows you to quickly start most 12.0V voltage cars with engines up to 4.0 litre petrol or diesel. This provides reliable ignition when the battery is weak or depleted, helping you get back on the road faster. - Low temperature performance: built-in high-performance chip ensures cold-start capability and reduces frost risk. It can be used normally in low temperature environments, and the built-in temperature protection resistor helps it operate accurately even in environments with large temperature differences. - Integrated air compressor: doubles as an inflation pump with multiple air nozzles to easily inflate car, motorcycle, and bicycle tyres, as well as balls and other inflatables such as swimming rings. Preset tyre pressure and auto-stop when full prevent over-inflation and save time. - Built-in battery and LED light: contains a high-capacity battery with long service life, and can be used as a power bank to charge phones, tablets, or other devices. The built-in LED light provides normal lighting, SOS mode, and flashing options, making it useful for night use or emergencies. Use scenarios: - Roadside jump-start in cold weather: quickly start a vehicle with a dead or weak battery to resume driving without needing a separate charger. - Road trip tyre maintenance: inflate car, motorcycle, or bicycle tyres to the desired pressure with automatic stop, saving time and ensuring correct inflation. - Outdoor camping or emergency lighting: charge mobile devices on the go and use the LED light for illumination, signaling, or SOS in low-light situations.
