Yes. This jump starter supports starting batteries with voltage levels ranging from 0V to 12.6V, including dead batteries when using the BOOST START MODE.
Can I Use It in Winter at -20°C?
Yes, absolutely. However, for the best performance in severe cold conditions, we highly recommend warming the unit inside your jacket or near the vehicle heater for several minutes before use. Extreme temperatures naturally reduce lithium battery discharge performance.

24 Months Ultra-Long Standby. Thanks to our advanced low self-discharge technology, this jump starter can retain its charge for up to 24 months. Even though the hardware can easily survive 24 months without a charge, we strongly recommend recharging the battery every three months; this is highly effective in extending the battery's health and lifespan.
