The YUSMAN 9000A Jump Starter with a built-in 160 PSI air compressor is a portable all-in-one emergency power and tire-inflation kit designed to restart 12V vehicles up to 10.0L diesel engines and inflate tires quickly while doubling as a 21800mAh power bank.

Compact but heavy-duty, this YUSMAN unit combines a high-output 9000A jump starter, smart safety jump cables, digital LCD readout, and a fast 160 PSI inflator into a single portable kit. It’s built to operate in a wide temperature range and offers multiple charge cycles, USB output for mobile devices, and a multi-mode LED light for roadside emergencies. The kit arrives with clamps, inflation accessories, and an EVA storage case so everything is ready to use out of the box.

How quickly will the YUSMAN jump starter get my car running?

The 9000A peak current is engineered to deliver enough cranking power to start most 12V gasoline engines and diesel engines up to 10.0L. In practice it can restart an unloaded 12V vehicle within seconds under normal conditions and maintain reliable starts across many cycles.

• Peak 9000A output for fast cranking power
• Supports gas engines and up to 10.0L diesel engines
• Operates between -4°F and 140°F for varied climates
• Up to 60 jump starts per full charge, 1000+ recharge cycles

What does the built-in air compressor do and how accurate is the gauge?

The integrated 160 PSI inflator doubles as a tire pressure monitor and inflates tires, sports equipment, and inflatables. A smart chip keeps the compressor stable and quieter while the LCD displays real-time pressure and allows you to preset a target value so inflation stops automatically when reached.

• Max 160 PSI for cars, SUVs, bikes, and inflatables
• Real-time tire pressure readings on the LCD screen
• Preset stop and four pressure unit options for convenience
• Includes pump tube and four air nozzles for multi-use

How safe and convenient is the YUSMAN unit for everyday use?

Safety features are built into both the smart clamps and the internal circuitry to prevent reverse polarity, short circuits, over-current, and overheating. The pack also functions as a 21800mAh power bank with fast USB charging, plus an LED light with normal, SOS, and strobe modes for nighttime visibility.

• Intelligent jump cables with multi-layer protection
• LCD gives clear status on mode, pressure, and battery
• Two USB ports including a fast-charge output for phones/tablets
• Integrated work light with SOS and strobe for emergencies

What comes in the box and how should I care for it?

The kit arrives with everything needed to jump-start, inflate, and charge devices: heavy-duty clamps, pump tube, four air nozzles, a USB-C cable, an EVA storage case, and a user manual. Initial and ongoing care recommendations help preserve battery health and ensure readiness.

• Includes jump starter pack, clamps, pump attachments, USB-C cable, and case
• Charge fully upon first receipt; recommended start when >25% charge
• Recharge the unit every 2–3 months to maintain battery lifespan
• Store in the EVA case to protect from dust and impact

Who is this for? The YUSMAN 9000A Jump Starter with Air Compressor is aimed at drivers, fleet operators, and outdoor enthusiasts who want a single compact device that covers battery failure, tire inflation, device charging, and low-light emergencies. It’s especially useful for those who travel in varied temperatures, need dependable starts for larger engines, or prefer a well-organized kit that stays ready in a trunk, garage, or truck bed.
