Setup

Before first use, ensure the GP4000 is fully charged. Refer to the "Charging the GP4000" section for instructions.

Connecting the Smart Jumper Cables:

1. Insert the blue end of the smart jumper cable into the jumper cable socket on the GP4000 unit. Ensure it is fully inserted.
2. Connect the red clamp (+) to the positive terminal of the vehicle's battery.
3. Connect the black clamp (-) to the negative terminal of the vehicle's battery.
4. Observe the indicator light on the smart jumper cable. A blinking green light indicates it's ready to jump-start. If the battery voltage is extremely low, press the "BOOST" button on the smart jumper cable module to forcefully restart the car.

Operating Instructions

Jump Starting a Vehicle:

1. Ensure the GP4000 has at least 50% charge.
2. Connect the smart jumper cables to the GP4000 and then to the vehicle battery terminals as described in the "Setup" section.
3. Once the indicator light on the smart jumper cable is solid green (or after pressing BOOST for very low batteries), start your vehicle's engine.
4. Once the vehicle starts, immediately remove the smart jumper cables from the vehicle battery, then disconnect them from the GP4000 unit.

Important: Do not crank the engine for more than 3 seconds per attempt. Wait at least 30 seconds between attempts to allow the jump starter to cool down. If the vehicle does not start after 3 attempts, consult a professional mechanic.

Using as a Power Bank:

• Connect your electronic device to one of the USB output ports (USB-A or USB-C) on the GP4000 using an appropriate charging cable.
• The GP4000 will automatically begin charging your device.

Charging the GP4000

The GP4000 can be recharged via its USB Type-C input port. A wall charger is not included.

• Connect the provided USB to Type-C cable to the GP4000's Type-C port.
• Connect the other end of the USB cable to a compatible USB wall charger (5V/3A recommended) or a car charger.
• The LED indicators on the GP4000 will illuminate to show the charging progress. A full charge typically takes about 5 hours.

Maintenance

• Store the GP4000 in its EVA storage case when not in use to protect it from dust and damage.
• If the jump starter has been idle for an extended period, it is advisable to charge it every 2-3 months to maintain its optimal condition and battery life.
• Clean the unit with a dry, soft cloth. Do not use harsh chemicals or abrasive materials.
• Keep the smart jumper cable clamps clean and free of corrosion for optimal conductivity.

Troubleshooting

Unit does not turn on:

• Ensure the unit is charged. Recharge if necessary.
• Press and hold the power button for a few seconds.

Vehicle does not start:

• Check that the smart jumper cables are securely connected to both the GP4000 and the vehicle battery terminals. Ensure good contact.
• Verify the GP4000 has at least 50% charge.
• If the vehicle battery is extremely low, press the "BOOST" button on the smart jumper cable module.
• Do not attempt to crank the engine for too long. Allow the jump starter to cool down between attempts.
• Ensure the vehicle's battery is 12V.

Smart Jumper Cable indicator light issues:

• Solid Red: Reverse polarity. Disconnect and reconnect clamps correctly.
• Flashing Red: Short circuit. Check for proper connection and ensure clamps are not touching each other.
