5. Maintenance
- Regular Charging: For optimal battery health and longevity, avoid completely draining the battery frequently. It is recommended to keep LiFePO4 batteries between 20% and 80% charge for daily use.
- Long-Term Storage: If storing the unit for an extended period, ensure the battery is charged to approximately 50%. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Cleaning: Keep the unit clean and free from dust and debris. Use a soft, dry cloth to wipe down the exterior. Ensure ventilation ports are clear to prevent overheating.
- Firmware Updates: Periodically check for firmware updates via the smart app to ensure optimal performance and access to new features.
6. Troubleshooting
- Unit Not Powering On: Ensure the unit is adequately charged. If the battery is completely drained, connect it to an AC power source for initial charging.
- No Output from Ports: Verify that the specific output port (AC, DC, USB) is activated on the main unit. Check the display for any error messages or overload indicators.
- Overload Protection: If an overload occurs, the system's protection mechanism may shut down output. Disconnect some devices and restart the output.
- App Connectivity Issues: Ensure Bluetooth is enabled on your mobile device and the AFERIY P310 Main Unit. Try restarting both the app and the main unit.
- Unusual Noise/Heat: The unit has built-in fans for cooling, which may activate during heavy use or charging. If excessive noise or heat persists, or if you notice any unusual smells, discontinue use and contact customer service.
