Choose countryThe UTRAI JS9 is a portable car jump starter with an integrated air compressor, power bank function and LED torch. It delivers 800 A peak current and 400 A starting current, supporting petrol engines up to 6 L and diesel engines up to 4.5 L.
Engine starting and tyre inflation
The stated starting voltage is 14.8 V, with a maximum of 16.6 V and 4 cells. The device allows up to 40 starts per charge and operates from -20 to 60 °C. A green indicator on the smart starter cable confirms correct battery connection.
The compressor provides up to 150 PSI. Set a target pressure in PSI, BAR or KPA and it stops automatically when that value is reached. Inflating a standard car tyre to 20 PSI takes approximately 3 minutes. It also supports bicycle tyres, balls, air mattresses and other inflatable accessories.
Power, lighting and controls
- Power bank: a 55.5 Wh / 15 000 mAh battery and USB output with fast-charging support; a USB-C input recharges the JS9 itself.
- 2-inch LED display: shows battery charge, compressor mode, current pressure and saved target values.
- LED torch: standard light, strobe and SOS modes.
- Protection: 10 protection systems, including overcharge, overload, short-circuit, reverse-polarity and overheating protection, plus automatic connection detection and real-time alerts.
The device measures approximately 20.5 × 15.5 × 7.5 cm and weighs 1.3 kg.
