The UTRAI JS40 multifunction jump starter won’t leave you stranded with a dead battery or when you need to quickly inflate a tire. It delivers a peak current up to 6000 A and can start gasoline and diesel engines up to 12.0 L. The Force Start function provides the extra boost when normal starting isn’t enough.
The built-in digital compressor offers easy target-pressure setting, 6 practical presets, and automatic shut-off once the set value is reached. In addition to inflation, it also supports a blowing mode—useful for inflatable mattresses, other outdoor gear, or quickly blowing away dust. A dual high-contrast LCD display keeps you informed about operation.
UTRAI JS40 also works as a power bank for mobile devices thanks to 30W PD fast charging (USB-C/USB-A). For safe operation, it features 12 intelligent protection systems and a durable design made from flame-retardant materials (Class V). In the dark, you’ll appreciate the wide-angle LED emergency light with steady, SOS, and strobe modes.
