[PSE Certified & 10 Smart Protection Functions] The ASMAX Jump Starter & Electric Pump is PSE certified and comes equipped with 10 safety protection functions, including protection against reverse connection, sparks, short circuits, overcharging, overvoltage, overcurrent, high temperature, low temperature, overload, and reverse current. It uses smart jumper cables, so anyone can use it safely without worrying about sparks or incorrect connections.
4000A Peak Current and Powerful Jump Start: Compatible with gasoline vehicles up to 9.0L and diesel vehicles up to 6.5L. Instantly jump-start a wide range of vehicles, including motorcycles, SUVs, trucks, and lawn mowers. A full charge provides up to 25 jump starts and operates reliably in temperatures ranging from -20°C to 45°C. We recommend leaving the battery at least 50% full during use.
[Stable lithium battery technology, lightweight and portable, ready for use at any time] The high-energy-density lithium battery makes it smaller, lighter, and easier to store in your vehicle. Because it stores its own energy, there's no need to pre-charge it like a supercapacitor, and it can start instantly, even in a cold winter parking lot or on the highway during a business trip. It can withstand hundreds of recharges, has a long life, and provides stable output throughout the year. It boasts excellent cost performance as an "in-vehicle private rescue team" that can save you money on JAF and towing fees.
[150 PSI Electric Air Pump with Auto-Shutoff Function] This high-powered air pump features a maximum pressure of 150 PSI and 35 L/min. It can inflate tires from 28 to 36 PSI in just one minute. It features five preset modes (Ball, Bicycle, Motorcycle, Car, and Custom) for easy operation. Real-time air pressure display (with ±0.01 BAR accuracy) and an automatic shutoff function when the set pressure is reached prevent overfilling for safe use. The 50 cm air hose easily reaches high and low points on your vehicle. Instantly adjusts to any tire!
[12000mAh Large Capacity & Mobile Function] The built-in 12000mAh large capacity battery not only functions as a jump starter but also charges smartphones and tablets. It can be fully charged in approximately 3 to 4 hours. It can also be used as an air pump for 20 to 30 minutes continuously, enough to fill approximately 30 to 40 bicycle tires.
[5-in-1 Multifunctional Design & 3-Year Warranty] In addition to being a jump starter, air compressor, and mobile device, it also features a high-brightness LED light (constant on/flashing/SOS). This multi-functional model has 5 functions in 1, making it useful at night or in emergencies. Your order number serves as your warranty card, and it comes with a 2-year manufacturer's warranty plus an additional 1-year warranty with official registration. In the unlikely event of a malfunction, we'll replace it, eliminating the need to wait for repairs.
