Start your car. Reinflate your tires. Stay ready on the road.

The BLUSTARX 4000A 4-in-1 with built-in air compressor is designed to handle real roadside emergencies. Whether you are dealing with a dead battery, low tire pressure, or a phone that needs charging, this compact device helps you manage the situation without waiting for roadside assistance.

With a 4000A peak current, it can quickly jump-start 12V vehicles and supports engines up to 8L gas and 6L diesel. Its built-in 150PSI smart air compressor provides fast tire inflation, with automatic shut-off to help prevent overinflation.

It also works as a 12000mAh power bank with an 18W USB-A output, while the built-in 800-lumen emergency LED light offers multiple lighting modes: steady light, strobe, and SOS, ideal for nighttime repairs or unexpected situations.

Equipped with 10 safety protections, including protection against reverse polarity, short circuits, overcurrent, overheating, overcharging, and overvoltage, it is designed for safer and more reliable use.

Keep it in your car, garage, or travel kit — and hit the road with confidence, ready to handle dead batteries, flat tires, and unexpected emergencies.
