7. Important Safety Notes
- Normal Heat Emission: The power bank may generate mild warmth (35°C–42°C) during use. This is a common thermal behavior in compact lithium-ion devices.
- Built-in Overheat Protection: The device automatically pauses charging if temperatures exceed 45°C, ensuring compliance with IEC 62368-1 safety standards.
- Optimize Magnetic Alignment: For stronger adhesion (recommended 12N pull force), pair with a magnetic phone case (e.g., Apple MagSafe-compatible models). Direct attachment to non-magnetic surfaces may reduce hold stability by 50%, potentially affecting charging efficiency.
- Do not expose the power bank to extreme temperatures, direct sunlight, or water.
- Do not disassemble, modify, or attempt to repair the device.
- Keep out of reach of children.
8. Maintenance
- Clean the power bank with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Store the power bank in a cool, dry place when not in use.
- Charge the power bank at least once every three months to maintain battery health.
9. Troubleshooting
- Device not charging: Ensure the power bank is charged. Check cable connections for wired charging. For wireless charging, ensure proper alignment and MagSafe compatibility.
- Slow charging: Verify that your device and cable support fast charging. Ensure the power bank has sufficient charge.
- Power bank overheating: If the power bank becomes excessively hot, disconnect it from your device and allow it to cool down. Overheat protection will temporarily pause charging if temperatures exceed safe limits.
