Operating Instructions

Jump Starting a Vehicle

Follow these steps carefully to jump start your vehicle:

1. Connect Jumper Cables to Jump Starter: Insert the blue end of the intelligent protection jumper cable into the jump start socket (DO port) on the jump starter. Ensure it is firmly connected.
2. Connect to Car Battery:
   • Connect the red clip to the positive (+) terminal of your car battery.
   • Connect the black clip to the negative (-) terminal of your car battery.
3. Start Car Engine: Return to your vehicle and start the engine.
4. Disconnect Cables: Once the vehicle has started, immediately remove the jumper cables from the car battery terminals, then disconnect the blue end from the jump starter. It is recommended to remove the clips within 30 seconds of starting the vehicle.

Using the LED Flashlight

The jump starter includes a multi-function LED flashlight for various emergency situations.

• Torch Mode (Normal Lighting): Press and hold the "Power" key for 3 seconds to turn on the constant light mode. This mode is suitable for general illumination, camping, or exploring.
• Flashing Mode (Strobe): Press the power button again to activate the high-frequency flash. This mode can be used to attract attention or deter danger.
• SOS Mode: Press the power button a third time to activate the SOS signal, which flashes a distress signal (3 short, 3 long, 3 short).

Charging Electronic Devices (Power Bank Function)

The jump starter can also function as a power bank to charge your mobile phones, tablets, and other USB-powered devices.

• Connect your device to the USB output port(s) using a compatible USB cable.
• The device supports fast charging for compatible phones.
• Note that the efficiency for charging phones/tablets is approximately 50%, and it is recommended for urgent needs.

Maintenance

• Regular Charging: To prolong the lifespan of the lithium battery, charge the jump starter every 3 months, even if it has not been used. Low power levels can affect its ability to jump start a vehicle.
• Storage: Store the device in its protective case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use harsh chemicals or abrasive cleaners.

Troubleshooting

If you encounter issues with your GKFLY Jump Starter, refer to the following common problems and solutions:

• Device not turning on or display is dark:
  • Ensure the device is charged. Connect it to a power source and check if the charging indicator lights up.
  • If the device was stored for a long time without charging, the battery might be deeply discharged. Try charging it for an extended period.
• Jump starter fails to start the car:
  • Verify that the jump starter has sufficient charge (ideally 100%). A low charge (e.g., below 15%) might not provide enough power.
  • Check that the red (+) and black (-) clips are correctly and securely connected to the corresponding car battery terminals.
  • Ensure the blue connector of the jumper cables is fully inserted into the jump starter's DO port.
  • The car battery might be severely damaged or completely dead, requiring professional assistance.
• Device not charging:
  • Try a different USB charging cable and power adapter.
  • Ensure the charging port on the jump starter is clean and free of debris.
  • If the device is new, ensure it's been charged for the recommended time (e.g., 6 hours for RATEL).
• Rapid discharge during the last 15% power:
  • This is a normal characteristic of high-rate lithium batteries and does not indicate a product defect.

User Tips

Based on user experiences, here are some helpful tips:

• Keep it Charged: Many users emphasize the importance of keeping the jump starter fully charged. A fully charged unit performs reliably.
• Check Charge Regularly: Even if not used, check the charge level every few months and top it up.
• Emergency Power Bank: While it can charge phones, its primary function is jump-starting. Use the power bank feature mainly for emergencies due to its efficiency.
• Portability: The compact size and included case make it easy to store in your car, even under seats.
