KEETEC CJS3000-TI

2-in-1 jump starter and tyre inflator

The CJS3000-TI combines a jump starter and a tyre inflator in one unit. With 3000 A peak current it starts a car with a flat battery, and the built-in compressor inflates tyres from 0.5 to 10.3 bar. Just set the target pressure – the compressor stops automatically once it's reached. A clear LCD shows pressure in bar or PSI along with battery status.

How to use

How to jump-start a 12 V vehicle

The jump starter must be charged above 20%. Don't press BOOST until the clamps are correctly connected to the vehicle battery.

01Plug the blue connector of the jumper cables into the jump starter.
02Connect the red clamp to the positive (+) and the black clamp to the negative (−) battery terminal.
03When the indicator shows steady green, start the engine.

What the indicator means

Steady green: The clamps are connected correctly and the unit is on. You can start the engine.
Steady red: The clamps are reversed. Reconnect them correctly and continue once the light turns green.
Flashing green: The vehicle battery voltage is too low. Press BOOST and, once the green light is steady, start within 30 seconds.
No light: The vehicle battery may be damaged or unresponsive. Check the clamps, press BOOST and, once the green light is steady, start within 30 seconds.
