UTRAI JS9 Multifunctional Car Starter

UTRAI JS9 Multifunctional Car Jump Starter

The UTRAI JS9 multifunctional car jump starter is a device you’ll want to keep on hand at all times—whether you’re heading out on a long trip or just popping out to the store. It combines powerful starting power, an efficient air compressor, a power bank function, and practical LED lighting, making it ideal for both everyday use and emergency situations. It’s a device that enhances the comfort and safety of every trip.

Power to start almost any vehicle

Hidden beneath the starter’s housing is an efficient starting system that can easily handle starting 12V vehicles—from motorcycles and passenger cars, through ATVs and snowmobiles, all the way to boats, RVs, and tractors. It supports gasoline engines up to 8.5 L and diesel engines up to 6.5 L, and allows for up to 40 starts on a single charge. Importantly, the device maintains high performance even in harsh conditions—it operates in a wide temperature range from -20°C to 60°C, ensuring a reliable start regardless of the weather.

Built-in Compressor

The integrated compressor, with a maximum pressure of 150 PSI, allows you to quickly inflate tires or other accessories. Simply set the target value in your chosen unit (PSI, BAR, or KPA), and the device will automatically stop once the appropriate level is reached. Inflating a standard car tire to 20 PSI takes about 3 minutes, making the JS9 a practical tool for drivers, cyclists, and outdoor enthusiasts alike (it also works with balls, air mattresses, and inflatable accessories).

Clear display and intuitive operation

The 2-inch LED display provides full control over the device’s operation. You can check the battery charge level, compressor operating mode, current pressure, and saved target values in real time. Additionally, the smart jumper cables are equipped with an indicator system—a green light signals a proper connection to the battery, which significantly simplifies operation and eliminates the risk of errors.

Power always at your fingertips

The built-in 15,000 mAh battery allows the device to also function as a powerful power bank. You have access to USB ports with various specifications (5V/3A, 9V/2A, 12V/1.5A) and Quick Charge 3.0 fast charging via USB-C (5V/2A, 9V/2A). This allows you to easily charge your smartphone, tablet, headphones, watch, or even a drone. Compared to heavy, traditional battery-powered jump starters, the JS9 offers significantly greater mobility and ease of use.

LED Lighting and Emergency Features

The integrated LED flashlight with three modes (standard light, strobe, and SOS signal) proves invaluable in emergency situations. The powerful, bright light makes working after dark easier, improves visibility on the road, and comes in handy during camping trips or other outdoor activities. It’s a practical addition that enhances the device’s functionality in all conditions.

Compact size and full safety

Despite its wide range of capabilities, the device remains compact (approx. 20.5 × 15.5 × 7.5 cm) and weighs only about 1.2 kg, making it easy to fit in a trunk or storage compartment. Safety is ensured by as many as 10 protection systems, including safeguards against overcharging, overloading, short circuits, reverse polarity, and overheating. Automatic connection detection and clear real-time alerts ensure that using the device is completely safe and free from the risk of electric shock.
