UTRAI JS9 Multifunction Car Starter

UTRAI JS9 Multifunctional Car Jump Starter

The UTRAI JS9 multifunctional car jump starter is an essential device for every driver, suitable for long trips or everyday errands. It combines powerful jump-start capabilities, an efficient air compressor, a high-capacity power bank, and practical LED lighting, enhancing both comfort and safety on the road.

Powerful Vehicle Starting Capability

Equipped with a high-performance starting system, the JS9 delivers a peak current of 800 A and a starting current of 400 A. It supports vehicles with a nominal voltage of 14.8 V (maximum 16.6 V, 4 cells), capable of starting motorcycles, passenger cars, ATVs, snowmobiles, boats, RVs, and tractors. It is compatible with gasoline engines up to 6.0 L and diesel engines up to 4.5 L, providing up to 40 starts on a single charge. The device operates reliably in a wide temperature range from -20°C to 60°C, ensuring performance in various weather conditions.

Integrated Air Compressor

The built-in compressor delivers a maximum pressure of 150 PSI, allowing quick inflation of tires and other inflatables. Users can set the target pressure in PSI, BAR, or KPA, and the compressor automatically stops upon reaching the desired value. Inflating a standard car tire to 20 PSI takes approximately 3 minutes. The compressor is also suitable for inflating balls, air mattresses, and other accessories.

Intuitive Operation with LED Display

A 2-inch LED screen provides real-time information including battery charge level, compressor mode, current pressure, and saved target values. The smart starter cables feature an indicator system with a green light confirming proper battery connection, simplifying use and preventing errors.

High-Capacity Power Bank Function

The internal 55.5 Wh (15,000 mAh) battery enables the JS9 to function as a power bank. It includes a USB output port supporting fast charging (5 V / 3 A; 9 V / 2 A; 12 V / 1.5 A) for smartphones, tablets, headphones, watches, and drones. The USB-C input (5 V / 2 A; 9 V / 2 A) allows efficient recharging of the device itself. Its compact and lightweight design offers greater mobility compared to traditional jump starters.

LED Lighting and Emergency Features

The device includes a built-in LED flashlight with three modes: standard light, strobe, and SOS signal. This lighting enhances visibility during nighttime operations, roadside emergencies, and outdoor activities such as camping.

Compact Design and Comprehensive Safety

Measuring approximately 20.5 × 15.5 × 7.5 cm and weighing 1.3 kg, the JS9 is easy to store in a vehicle trunk or compartment. It incorporates 10 safety protection systems, including safeguards against overcharging, overloading, short circuits, reverse polarity, and overheating. Automatic connection detection and real-time alerts ensure safe and error-free operation.
