With the same battery capacity, our new Quick Discharge Start Power jump starter has 3-5 times enhanced current compare to the old 2nd generation. At the same time, it can balance the temperature by reducing the start-up temperature through disruptive innovation of the battery/assembly structure to ensure a safe start.The car jump starter can jump-start your vehicle (up to 7.5L gas or 6.5L diesel engine) up to 20 times with 2000-amp peak current and heavy-duty clamps and cables. Additionally, our battery starter could start trucks, motorcycles, snowmobiles, ATV, UTV, lawnmowers, and yachts up in a few minutes, even in extreme temperatures (-4°F~140°F). The car battery jump starter pack is safe and easy to use without the worry of incorrect connections or sparks. It is spark-proof, has reverse polarity protection, low voltage protection, high-temperature protection, and over-load protection. You can safely connect it to any 12-volt automotive car battery. The specially designed indicator notifies you of incorrect use with an audible buzz and flashing lights.
