Joysun's emergency auto parts starter integrates four key functions—rapid engine starting, tire inflation, portable charging, and LED lighting—into a single device for versatile use. Compatible with all 12V/24V vehicles, it eliminates compatibility concerns. Equipped with high-performance battery cells, it delivers 150C peak discharge and 40C continuous discharge rates, ensuring reliable starts even in extreme cold and harsh conditions. The 150C peak discharge provides a massive current burst to crank a completely dead engine, while 40C continuous discharge supports repeated start attempts. The entire product line is certified with multiple international safety standards, including UL, CE, and 3C, making it an essential emergency companion for your vehicle, whether for passenger cars or commercial trucks.
