About This

• 【6000A POWERFUL JUMP STARTER】Powered by a powerful lithium battery with up to 6000A peak current, the UTRAI JS-40 car battery jump starter features smart clamps with forced start. Reliably jump-starts all gasoline engines and up to 10.0L diesel engines, including trucks, SUVs, and pickups—the jump pack are perfect for emergency roadside situations.
• 【High-Quality Copper Cables】Made with pure copper cables supporting up to 60A continuous current (30A for aluminum wires). These ratings refer to long-term use like household appliances, but car engines only need short bursts of high current for 1–2 seconds, which is fully safe. In fact, car batteries can produce instantaneous currents over 1000A for very short durations (~0.1s), so the cables easily handle engine starts.
• 【Inflate & Deflate Air Pump】The car jump starter is equipped with a 150 PSI, 19-cylinder high-pressure air pump for tires and a separate blower mode. This car jump starter makes it easy to inflate car, motorcycle, and bike tires, as well as sports balls and air mattresses—or use blower mode to inflate swim rings, blow away dust, or vacuum-seal down jackets. Includes 1 hose + 4 nozzles.
• 【150 PSI TIRE INFLATOR】The car starter supports real-time tire pressure monitoring and automatically stops when preset pressure is reached. The jump box with air compressor has six modes including Car, Motorcycle, Bicycle, Basketball, Blower, and Custom, ensuring safe and accurate inflation every time.
• 【PD30W FAST CHARGING OUTPUT】Functions as a portable power bank with PD 30W Type-C output, QC3.0 18W USB-A output, and 18W Type-C fast input. This portable car jump starter lets you quickly charge your phone, tablet, smartwatch, Bluetooth speaker, and other devices wherever you are.
• 【10 Safety Protections & Emergency Lighting】The jump box with air compressor features 10 integrated safety protections for reliable, worry-free use, including reverse polarity, short circuit, over-current, over-voltage, over-charge, over-discharge, overload, overheat, spark-proof, and low-temperature protection. Made with V0 fire-retardant materials, operating safely from -20°C to 60°C. Includes 3-mode LED light (Steady / SOS / Strobe), LED digital display, and a portable storage bag.
