6.2 Understanding the Digital Display

The smart digital display provides comprehensive information:

• Remaining Battery: Shows the current battery percentage (e.g., 100%).
• Time to Recharge / Remaining Battery in Hour: Displays an estimate of how long until the power bank is fully charged (IN) or how much charge time is left (OUT) (e.g., 99h 99m).
• IN/OUT Indicators: Clearly indicates whether power is flowing IN (charging the power bank) or OUT (charging a device).
• Wattage (W), Voltage (V), Amperage (A): Shows the real-time power delivery metrics for both input and output.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the power bank. Do not use liquid cleaners or aerosols.
• Storage: Store the power bank in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For optimal battery life, fully charge the power bank at least once every three months if not in regular use.
• Avoid Drops: Protect the device from drops and impacts, which can damage internal components.

8. Troubleshooting

8.1 Power Bank Not Charging / Not Charging Devices

• Check Cables: Ensure all charging cables are securely connected to both the power bank and the wall charger/device. Try using a different cable to rule out a faulty cable.
• Check Power Source: If charging the power bank, ensure the wall charger and power outlet are functioning correctly. Try a different wall charger or outlet.
• Power Bank Charge Level: Ensure the power bank itself has sufficient charge. If it's completely depleted, it might take a few minutes to show a charging indicator.
• Device Compatibility: Verify that your device is compatible with the power bank's output specifications.
• Restart: Disconnect and reconnect all devices and cables to reset the connection.

8.2 Slow Charging

• Cable Quality: Use high-quality, fast-charging compatible cables. Low-quality or damaged cables can significantly reduce charging speed.
• Charger Output: For charging the power bank, use a wall charger that supports 45W PD or higher. For charging devices, ensure the cable and device support the fast charging protocols (PD, QC, AFC, SCP) of the power bank.
• Simultaneous Charging: Charging multiple devices simultaneously may distribute the total output, potentially slowing down individual device charging.

9. User Tips

• For the fastest recharge of the power bank, always use a 45W (or higher) USB-C Power Delivery compatible wall adapter.
• Take advantage of the digital display to monitor charging speeds and remaining battery life, helping you plan your power usage effectively.
• This power bank is designed to be travel-friendly and is allowed aboard airplanes, making it an ideal companion for long journeys.
