Jump Starting a Vehicle

Ensure jump starter is charged above 50%.

Turn off the vehicle's ignition and all electronics (lights, radio).
Press the POWER button on the jump starter to turn it on.
Connect RED clamp to the positive (+) terminal of the dead battery.
Connect BLACK clamp to a clean, unpainted metal part of the engine block or chassis (ground), NOT to the negative (-) terminal of the dead battery.
Ensure connections are secure. The unit will perform a self-check; if polarity is correct, a green light will illuminate on the clamp.
Start the vehicle. It should start within 3-5 seconds. If it doesn't, wait 30 seconds and try again.
Once vehicle is running, disconnect BLACK clamp first, then RED clamp.
Turn off the jump starter by pressing and holding the POWER button.

Tip: If the vehicle doesn't start after 3 attempts, the battery may be beyond recovery or there may be another issue.
