About this item
【Large Capacity】The YUSMAN car battery booster delivers a powerful peak current of 5000A and a capacity of 21800mAh, designed for most 12V vehicles—especially all petrol and 10.0L diesel engines. This car jump starter starts your battery instantly, even in harsh temperatures ranging from -40°C to 60°C. Suitable for cars, trucks, motorcycles, water scooters, lawnmowers, yachts, pick-ups, snowmobiles, and more. With this booster, you’ll never worry about unexpected breakdowns—it starts your vehicle in seconds.
【Versatility】The YUSMAN car battery booster features an LCD screen that clearly displays real-time working status. It includes 4 practical LED modes: Lighting, SOS, Strobe, and Warning—ideal for travel, outdoor activities, and emergencies. Equipped with two USB ports (5V/3A), it can quickly charge smartphones, tablets, and other USB devices. Compact and lightweight, this portable car jump starter is easy to carry and store without taking up much space.
【Tyre Inflation Function】The YUSMAN battery booster has a built-in mini compressor with a maximum pressure of 150 PSI, perfect for inflating car tyres, air cushions, kayaks, sports balls, and more. Simply connect the hose to the tyre, press the start button, and inflate with ease. The LCD screen displays real-time tyre pressure, so you can always stay aware of your tyre conditions.
【Smart Clamp Safety Protection】The YUSMAN jump starter is equipped with large smart clamps and an intelligent protection system. The smart cables provide protection against short circuits, overheating, overvoltage, overload, deep discharge, overcurrent, and reverse polarity. Built with longer, thicker wires for better conductivity and wider openings, the clamps ensure a reliable connection. If connected incorrectly, audible and visual warnings activate immediately—making the device safe and user-friendly.
【Package Contents】The package includes: 1 x YUSMAN jump starter with air compressor, 1 x smart jump lead, 1 x air pump hose, 4 x air nozzles, 1 x USB-C charging cable, 1 x user manual, and 1 x portable EVA carrying case. If you have any issues with your YUSMAN car battery booster, feel free to contact us—our customer service team will respond within 24 hours.
【Note】Upon receiving your car battery booster, please fully charge it before first use—even if it shows partial charge. It is recommended to start your vehicle only when the jump starter battery is above 25%. To maintain performance and extend battery life, recharge the unit every 2–3 months.
