Quick Guide

The Gooloo GP2000 is a portable jump starter for 12V vehicles. Before use, ensure the device is charged to at least 50% (2 bars). If the device has not been used for more than two months, charge it fully before use. Always check the indicator lights on the smart jumper cable before attempting to start the vehicle.

Charging the Device

The unit can be charged using a USB-C cable and a 5V wall charger or car charger. The battery indicators will blink sequentially during charging and turn off when fully charged. Note that quick charge input requires a QC3.0 wall charger or car charger (sold separately).

Jump Starting a Vehicle

Ensure the unit has at least 50% battery.
Connect the smart jumper cable fully into the jump starter.
Connect the red clamp to the positive (+) battery terminal and the black clamp to the negative (-) battery terminal.
Check the indicator on the jumper cable:
- Green Light Solid: Connection is correct; you can start the vehicle.
- Red Light Solid + Beeping: Reverse connection; correct the clamp positions.
- Green Light Blinking: Vehicle battery is low; press the BOOST button, wait for the green light to turn solid, then start the vehicle within 30 seconds.
- No Lights/No Beeping: Vehicle battery may be damaged; press the BOOST button, wait for the green light to turn solid, then start the vehicle within 30 seconds.
Start the vehicle.
Remove the jumper cable from the jump starter and the vehicle battery immediately after the engine starts.

LED Flashlight Operation

Long press the power switch for 3 seconds to turn on the LED light. Press the switch lightly to cycle through the three modes: Normal, Strobe, and SOS. Use the same switch to turn the light off.

Safety Precautions

For 12V vehicles only. Do not use on aircraft or boats.
Do not use if cables or clamps are damaged.
Do not use as a replacement for a vehicle battery or as a battery charger.
Do not start the vehicle continuously more than 4 times within 2 minutes.
Do not connect the two clamps together.
Do not immerse in water or expose to extreme heat/fire.
Do not disassemble or modify the unit.

Troubleshooting

Green and Red light blinking: Over-start protection triggered. Disconnect the jumper cable and reconnect.
Unit won't charge: Try a different charging cable or wall charger.
No response when pressing power: Low voltage protection triggered; charge the unit.
Unit overheated/swelled: Stop use immediately and contact support.

Practical help

Common problems

Green and Red light blinking alternately

Over-start protection triggered. Disconnect the jumper cable from the starter and reconnect to reset.

Unit does not charge

Try using a different charging cable or wall charger. If the first battery indicator blinks continuously, the unit may be over-discharged or defective.

No response when pressing power switch

Low voltage protection is active. Charge the unit using a wall charger to activate it.

Before use

Ensure the unit is charged to at least 50% (2 bars).
Verify the vehicle is a 12V system.
Ensure battery terminals are clean and free of corrosion.
Charge the unit if it has been stored for more than two months.
Remove personal metal items like rings or necklaces before working with the battery.
