Jump-Starting Procedure

Follow these steps carefully to jump-start a vehicle.

Prepare: Ensure jump starter is OFF. Park vehicles in neutral/park with ignitions OFF.
Connect Red Clamp (+): Attach to the positive (+) terminal of the dead vehicle battery.
Connect Black Clamp (-): Attach to a clean, unpainted metal part of the engine block or chassis (ground), away from the battery and fuel lines.
Power On: Turn the jump starter's POWER switch to ON. The battery indicator will light up.
Start Vehicle: Start the disabled vehicle. It should start within 5-6 seconds of cranking.
Disconnect: Once vehicle is running, turn jump starter OFF. Remove BLACK clamp first, then RED clamp.
Recharge: Recharge the jump starter as soon as possible after use.

WARNING! If vehicle does not start after 2-3 attempts (wait 2 minutes between attempts), the battery may be severely discharged or faulty. Seek professional assistance.

Using the USB Port & LED Light

USB Charging:
1. Ensure jump starter is charged (at least one indicator light).
2. Connect your device (phone, GPS, etc.) to the USB port using your own cable.
3. The device will begin charging automatically. The jump starter will turn off automatically if the device is fully charged or disconnected.

LED Work Light:
