7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your power station.

• Battery Calibration: To maintain accurate battery level readings, it is recommended to occasionally drain the power station completely (to 0%) and then fully recharge it to 100% immediately. This helps reset the internal battery gauge.
• Storage: If storing the unit for an extended period, charge it to approximately 50-80% and store it in a cool, dry place away from direct sunlight. Recharge every 3-6 months to prevent deep discharge.
• Cleaning: Use a dry, soft cloth to clean the exterior of the power station. Do not use liquid cleaners or solvents.
• Inspection: Regularly inspect the unit and cables for any signs of damage. Do not use if damaged.

8. Troubleshooting

If you encounter issues with your GRECELL EB1000, refer to the following common troubleshooting tips:

• Unit Not Turning On: Ensure the battery is charged. If completely depleted, it may take a few minutes of charging before the unit responds.
• Device Not Charging/Powering:
  • Check if the specific output (AC, USB, DC) is enabled by pressing its respective button.
  • Verify that the device's power consumption does not exceed the output limit of the port or the total output limit of the power station (1000W).
  • Ensure the device is properly connected to the port.
• Wireless Charger Not Working: Ensure both the main POWER ON/OFF button and the 'USB' button are pressed to activate the wireless charging function. Confirm your device supports wireless charging and is placed correctly on the pad.
• Battery Gauge Inaccurate: Perform a full discharge (to 0%) followed by an immediate full recharge (to 100%) to recalibrate the battery gauge.
• Overload Protection Activated: If the unit shuts down due to overload, disconnect the high-power device, turn the power station off, then on again, and connect devices within the specified wattage limits.
• Overheating: The unit has cooling fans. If it feels excessively hot, ensure vents are not blocked and operate in a cooler environment. The BMS will shut down the unit if it overheats.
