To clean the power bank, gently wipe its surface with a soft, dry, lint-free cloth. Do not use harsh chemicals, abrasive cleaners, or immerse the device in water.

5.2 Storage

Store the power bank in a cool, dry place away from direct sunlight, extreme temperatures, and humidity. For long-term storage, it is recommended to charge the power bank to approximately 50-70% every three months to maintain battery health.

5.3 Battery Care

• Avoid fully discharging the power bank frequently.
• Do not expose the power bank to temperatures above 45°C (113°F) or below 0°C (32°F).
• If the power bank becomes noticeably hot during charging or discharging, discontinue use and allow it to cool down.

6. Troubleshooting

• Power bank not charging: Ensure the charging cable is securely connected to both the power bank and the power adapter. Try a different cable or adapter.
• Device not charging wirelessly: Ensure your device is compatible with magnetic wireless charging (iPhone 16/15/14/13/12 series). Remove any non-magnetic phone cases or use a MagSafe-compatible case. Ensure proper alignment.
• Device not charging via wired connection: Check the cable connection to both the power bank and your device. Try a different cable or port.
• Slow charging: Ensure you are using a fast-charging compatible cable and adapter for the power bank itself. For device charging, verify your device supports the fast charging protocols (PD or QC) and that the cable is appropriate. Charging multiple devices simultaneously may reduce individual charging speeds.
• Power bank gets hot: It is normal for the power bank to warm up during charging or discharging. If it becomes excessively hot, discontinue use and contact support.
