UTRAI JS40 Multifunctional Car Starter

UTRAI JS40 Multifunctional Car Jump Starter

The UTRAI JS40 Multifunctional Car Jump Starter combines a powerful jump-start booster, an efficient air compressor, and a practical air-blow mode, creating a device that works well both for everyday use and in emergency situations. It delivers a peak current of up to 6000A, allowing you to easily start gasoline and diesel cars up to 12L. The built-in compressor with digital control lets you quickly inflate tires or other accessories, while the fast-charging power bank function keeps your electronics powered on the go. The unit is complemented by a robust design with advanced safety features and a clear, dual LCD display. This is equipment that provides reliability and convenience no matter what situation you find yourself in.

Starting power you can count on

The UTRAI JS40 was designed with the most demanding situations in mind. A peak current of 6000A allows you to start a wide range of vehicles—from motorcycles and lawn mowers, through passenger cars, to SUVs and diesel vehicles with engines 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 predefined modes at your disposal, tailored to various applications—from car tires, through motorcycles and ATVs, all the way to lawn mowers. The device supports both inflating and deflating, and the auto-shutoff feature protects against over-inflation. Thanks to the set of nozzles, you can easily inflate mattresses, boats, or vacuum bags, and the blow-up mode is also great for dusting or preparing outdoor gear.

Power Bank with Fast Charging

The UTRAI JS40 is not only a jump starter but also a functional, high-performance power bank. It supports 30W PD fast charging, allowing you to easily charge smartphones, tablets, and other mobile devices. You have access to USB-A and USB-C ports, which offer both input (18W) and output (18W), allowing you to flexibly manage power in any situation. It’s the perfect solution for longer trips, off-road adventures, or everyday use.

Thoughtful 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 systems and high-quality chips work in tandem with a high-capacity battery and a brushless motor to ensure stable performance. A system of 12 intelligent safety features protects against overheating, overloading, 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 the most important information—from battery level to current operating parameters. Intuitive operation means that even less experienced users can handle it with ease. The features have been designed to simplify the use of the device as much as possible and reduce the time needed to perform a given task.

Emergency lighting that enhances safety

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