Powerful Jump Starter: Engineered to deliver a robust 5000A peak current, this car jumper starter portable quickly revives 12V vehicles with gas engines up to 9.0L and diesel engines up to 8.0L. Its intelligent automatic boost function activates when it senses an extremely low battery, providing that extra surge needed to turn the engine over. Fully charged, it can deliver up to 50 jump starts and operates dependably across a wide temperature range, from -4°F to 140°F, so you can trust it in both summer heat and winter cold.

Versatile Air Compressor: More than just a jump box for car battery, it features a high-performance tire inflator capable of reaching 160 PSI. With four preset inflation modes (Car, Motorcycle, Bicycle, Ball) and 5 included nozzles, it handles everything from car tires to sports equipment. The 30L/min airflow quickly inflates a standard 195/65 R15 car tire from 29 PSI to 36 PSI in about a minute. You can easily switch between four pressure units (PSI, BAR, KPA, kg/cm²) on the clear LCD screen.

5 IN-1 Multi-Function: This single device consolidates five essential tools: a portable car jump starter, a precise tire inflator, a high-capacity 20,000mAh power bank for charging devices via its USB-A port, a bright LED flashlight, and an SOS emergency signal light. It’s the ultimate preparedness kit for road trips, daily commutes, and unexpected emergencies, ensuring you’re never stranded without power or light.

Smart Wireless Inflation: The integrated smart LCD screen in this portable jump starter for car provides real-time pressure readings, so you always know exactly where you stand. Set your desired pressure, and the unit will automatically shut off when reached, preventing over-inflation. The detachable extension hose offers extra reach to valve stems, and the backlit screen remains perfectly readable even in direct sunlight for hassle-free daytime use.
