5. Operating Instructions: Jump Starting a Vehicle
Ensure the jump starter is at least 50% charged before attempting to jump start a vehicle.
- Prepare the Vehicle: Turn off the vehicle's ignition and all accessories (headlights, radio, air conditioning). Engage the parking brake.
- Connect Clamps to Jump Starter: Insert the blue plug of the smart jumper clamps firmly into the jump start port on the NEXPOW unit. Ensure a secure connection.
- Connect Clamps to Battery:
- Connect the RED (positive, +) clamp to the positive (+) terminal of the vehicle's battery.

An image illustrating the correct connection of the red clamp to the positive battery terminal and the black clamp to the negative battery terminal would be placed here.
Description: This image would clearly show the red clamp attached to the battery terminal marked with a '+' sign and the black clamp attached to the terminal marked with a '-' sign, or to a solid, unpainted metal part of the engine block for grounding.
- Check Indicator: The smart clamp indicator light should turn solid green, indicating a correct and safe connection. If it's red or flashing, check connections and troubleshoot.
- Start Vehicle: Return to the vehicle and start the engine. If the engine does not start immediately, wait 30 seconds before trying again. Do not crank for more than 3 seconds per attempt.
- Disconnect Clamps: Once the vehicle starts, immediately disconnect the BLACK (negative) clamp first, then the RED (positive) clamp from the vehicle battery.
- Disconnect from Jump Starter: Remove the smart jumper clamps from the jump starter unit.
