4. Maintenance
- Keep the power bank dry and away from moisture.
- Avoid exposing the power bank to extreme temperatures (hot or cold).
- Do not drop, disassemble, or attempt to repair the power bank yourself.
- Clean the surface with a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
- Store in a cool, dry place when not in use.
5. Troubleshooting
5.1 Device Not Charging
- Ensure the power bank is sufficiently charged. Check the digital display.
- Press the power button on the side of the power bank to activate charging.
- Verify that your device is properly aligned on the MagSafe or Apple Watch charging area, or that the cable is securely connected.
- Check if your phone case is MagSafe compatible. Non-MagSafe cases can interfere with wireless charging.
- Try a different charging cable or port if using wired charging.
5.2 Overheating During Wireless Charging
- Overheating can occur if the phone is not properly aligned or if a non-MagSafe case is used. Ensure proper alignment and use a MagSafe-compatible case or no case.
- The power bank features NTC temperature control to prevent excessive heat. If it gets too hot, it may temporarily reduce charging speed or stop charging to protect your devices.
- If overheating persists, discontinue use and contact support.
5.3 Slow Charging Speed
- Simultaneous charging of multiple devices can reduce the charging speed for each individual device.
- Wireless charging is generally slower than wired charging.
- Charging speed may decrease after the power bank reaches 75% capacity.
- If the power bank detects high temperatures, it may reduce charging speed to maintain safety and device health.
- Ensure your wall adapter (when charging the power bank) provides sufficient power (18W or higher) for optimal recharge times.
