Starting power you can count on

The UTRAI JS40 was designed with the most demanding situations in mind. Its 1,000 A peak current allows you to start a wide range of vehicles with a nominal voltage of 14.8 V —from motorcycles and lawn mowers to passenger cars, SUVs, and diesel vehicles with engine capacities up to 12 L. The force start function provides additional support in critical moments when a standard start proves insufficient. This solution eliminates the stress of a dead battery and gets you back on the road quickly.

Compressor and inflation mode

The integrated digital compressor offers fast inflation and the ability to set a target pressure, which significantly simplifies operation. You have 6 preset modes at your disposal, tailored to various applications—from car tires to motorcycles and ATVs, all the way to lawn mowers. The device supports both inflating and deflating, and the automatic shut-off feature protects against overinflation. Thanks to the set of nozzles, you can easily inflate mattresses, boats, or vacuum bags, and the blow-up mode is also great for removing dust or preparing outdoor gear.

Fast-charging power bank

The UTRAI JS40 is not only a jump starter but also a functional power bank with a capacity of 37 Wh / 10,000 mAh. It supports 30W PD fast charging, allowing you to easily charge smartphones, tablets, and other mobile devices. You have access to a USB-A output port and a bidirectional Type-C port that supports both input and output, allowing you to flexibly manage power in any situation. It’s the perfect solution for longer trips, outdoor adventures, or everyday use.

Well-thought-out design

Every component of the device has been designed with durability and safety in mind. The housing is made of Class V fire-resistant materials, and the use of thickened copper wires enhances reliability during operation. Advanced electronic circuits and high-quality chips work in tandem with a high-performance battery and a brushless motor to ensure stable operation. A system of 12 intelligent safety features protects against overheating, overload, and reverse polarity, so you can use the device with confidence.

Convenient operation in any situation

The high-contrast dual LCD display provides quick access to all key information—from battery level to current operating parameters. Intuitive operation means that even less experienced users can handle it with ease. The features are designed to simplify use as much as possible and reduce the time needed to complete a given task.

Emergency lighting that enhances safety

The built-in LED with a wide beam angle is ideal for both working after dark and in emergency situations. You can choose between continuous, SOS, and strobe modes, allowing you to tailor the lighting to your current needs. Whether you’re changing a tire at night or need a warning signal, the UTRAI JS40 will provide adequate visibility and extra support where it’s needed most.
