5. Setup and Charging
Initial Charging:
Upon receiving your EAFC Car Battery Jump Starter, it is essential to fully charge it before first use. The charging process typically takes 3-4 hours. For optimal battery life, it is recommended to perform an initial discharge by turning on the flashlight until the unit is depleted, then fully charge it for over 4 hours.
Charging the Device:
Connect the provided USB charger cable to the jump starter and a suitable power source. The display will indicate the charging status. Ensure the device is fully charged before attempting to jump-start a vehicle.
Figure 6: The jump starter can also charge other electronic devices like phones, tablets, and laptops.
6. Operation
6.1. Jump Starting a Vehicle:
Follow these steps carefully to jump-start your vehicle:
- Ensure the jump starter is sufficiently charged (more than 75% power recommended).
- Fully insert the battery clamp connector into the EC5 interface of the jump starter unit.
- Connect the red clamp to the positive (+) pole of the vehicle battery.
- Connect the black clamp to the negative (-) pole of the vehicle battery.
- Turn the vehicle's ignition switch to the START position.
- Once the car starts, immediately unplug the jump starter connector and remove the battery clamps within 30 seconds.
Important Notes for Jump Starting:
- Do not attempt to start the car continuously. Each starting attempt should not exceed 3 seconds.
- If the first attempt is unsuccessful, wait for more than 30 seconds before attempting a second start.
- The device features DO anti-reverse plug power interface and insulated fully covered chucks for safety, preventing leakage and incorrect connections.

6.2. Portable Power Bank Function:
The jump starter can be used as a portable power bank to charge various electronic devices via its USB output ports. Simply connect your device using a compatible USB cable.
Figure 9: The jump starter can charge phones, tablets, headsets, laptops, cameras, and game consoles.
6.3. Emergency Flashlight Function:
The device is equipped with a multi-mode LED flashlight for emergency situations, camping, or night repairs.
- To turn ON/OFF the LED: Long press the power button for 3 seconds.
- To change modes: Press the power button again briefly to cycle through modes: Illumination (always ultra-bright) → Strong Light Flashing → SOS (3 short - 3 long - 3 short) → Strobe (flash alternatively) → OFF.

7. Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Jump starter fails to start vehicle |
|
| LED flashlight not working | Long press the power button for 3 seconds to activate. |
| Slow charging/discharging at low battery levels | This is a characteristic of high-rate lithium batteries, especially during the last 15% of power. This is normal and does not affect product quality. |
| Device not holding charge | Charge every 3 months, even if not in use, to maintain battery health. |

8. User Tips
- Initial Use: Always perform an initial discharge (using the flashlight) and then a full charge (4+ hours) when you first receive the jump starter. This helps condition the battery.
- Regular Charging: To maintain battery health, charge the jump starter every 3 months, even if it's not being used. Low power can lead to failed starts.
- Jump Start Attempts: When jump-starting, ensure each attempt is brief (under 3 seconds) and allow at least 30 seconds between attempts to prevent overheating and allow the battery to recover.
- Power Bank Use: While the device can charge phones and tablets, its primary function is jump-starting. Use the power bank feature occasionally, as its conversion efficiency for charging other electronics is approximately 50%.
- Temperature Resilience: The jump starter is designed to operate in extreme temperatures from -20°C to +60°C, making it reliable in various climates.
9. Maintenance
- Storage: Store the jump starter in a cool, dry place. If not used, it can be stored normally for 3-6 months, but regular charging every 3 months is recommended to prevent deep discharge.
- Cleaning: Wipe the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Battery Care: Avoid completely draining the battery frequently. Always recharge it promptly after use.
