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

The BLUSTARX 4000A 4-in-1 with built-in air compressor is designed to handle real emergencies on the road. Dead battery, insufficient tire pressure, or a phone to charge: this compact device helps you manage the situation without waiting for roadside assistance.

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

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

Equipped with 10 safety protections, including reverse polarity, short-circuit, over-current, overheating, overcharge, and over-voltage, 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 deal with dead batteries, flat tires, and unexpected emergencies.
