The built-in compressor with digital control allows rapid inflation of tires and other accessories, while the 37 Wh / 10,000 mAh power bank with fast charging keeps your electronic devices powered on the go. The device features a robust design with advanced safety mechanisms and a clear dual LCD display, providing reliability and convenience in any scenario.

Reliable Starting Power

Designed for demanding conditions, the UTRAI JS40 offers a 1,000 A peak current to start a wide range of vehicles at 14.8 V nominal voltage, including motorcycles, lawn mowers, passenger cars, SUVs, and diesel engines up to 12 L. The Force Start function provides extra support when a standard start is insufficient, eliminating the stress of a dead battery and enabling quick vehicle restart.

Integrated Compressor and Inflation Modes

The digital compressor supports fast inflation with the ability to set target pressure, simplifying operation. It includes 6 preset modes tailored for various applications such as car tires, motorcycles, ATVs, and lawn mowers. The device supports both inflation and deflation, with an automatic shut-off feature to prevent overinflation. A set of nozzles allows inflation of mattresses, boats, and vacuum bags, while the air-blow mode is useful for dust removal and preparing outdoor equipment.

Fast-Charging Power Bank

Beyond jump-starting, the UTRAI JS40 functions as a power bank with 37 Wh / 10,000 mAh capacity. It supports 30 W Power Delivery (PD) fast charging, compatible with smartphones, tablets, and other mobile devices. It offers a USB-A output port and a bidirectional USB-C port for both input and output, providing flexible power management during travel or outdoor activities.

Durable and Safe Design

The device housing is made from Class V fire-resistant materials, and thickened copper wires enhance operational reliability. Advanced electronic circuits and high-quality chips, combined with a high-performance battery and brushless motor, ensure stable performance. Twelve intelligent safety features protect against overheating, overload, and reverse polarity, allowing confident and safe use.

User-Friendly Operation

A high-contrast dual LCD display provides clear information on battery level and operating parameters. The intuitive interface allows easy operation even for less experienced users, streamlining tasks and reducing completion time.

Emergency Lighting

The built-in wide-angle LED light offers continuous, SOS, and strobe modes, ideal for nighttime work or emergencies. It provides adequate visibility and warning signals when changing tires or in other roadside situations.
