STEP BY STEP
Emergency Jump Starters
PEACE OF MIND IN THE PALM OF YOUR HAND.
Below 30% charge, it may not start your engine
This unit is designed for jump starting 12V / 24V cars. Each type of start valve has different application ranges. Do not attempt to jump start vehicles with a higher battery voltage, or different voltage, or higher displacement.
If the vehicle isn't started immediately, please wait for 1 minute to allow the jump starter to cool down before next attempt. Do not try to restart the vehicle after three consecutive attempts as this may damage the unit. Check your vehicle for other possible reasons why it can't be restarted.
If your vehicle battery is dead or its battery voltage is under 2V, you need to use force start mode.
01Power on, plug in
Switch on your jump starter and make sure battery balance is over 30%. Insert the jump-start clamps into the port correctly and firmly.
02Red to +, black to −
Connect the jump-start clamps to the car battery terminals correctly (red to positive (+), black to negative (-)).
03Green light, then crank
Start the engine in 30s once the indicator light turns green.
04Unplug first, then remove
Remove the plug from the battery pack and remove the clamps from the car battery.
