How to Use: Jump Starting
You’ll need to be cautious but the process is straightforward with the smart clamp indicators to guide you. First, turn off the vehicle ignition and ensure both vehicles (if using another car) are in park and stable. Connect the red clamp to the positive terminal and the black clamp to the negative terminal or a grounded metal surface if instructed. The smart clamps will indicate proper connection and prevent spark if you connect them incorrectly. Start the vehicle and, once running, disconnect clamps in reverse order and recharge the unit as soon as practical.
Step-by-step Jump Start Instructions
You’ll follow simple steps: (1) Power on the jump starter, (2) attach clamps to battery terminals with the red to positive and black to negative, (3) watch for the green indicator or beep confirming proper connection, (4) start the car — if it doesn’t start, wait a minute and try again up to recommended attempts, and (5) remove clamps in reverse order and recharge the jump starter battery.
How to Use: Inflating Tires
You’ll run the pump either using the unit’s battery or by plugging the included cigarette lighter cord into your vehicle for indefinite operation.
