- Storan: Store the inflator in a cool, dry place away from direct sunlight and extreme temperatures.

6. Penyelesaian masalah
- Peranti tidak dicas: Ensure you are using a 5V (5-10W) charger. Chargers rated 15W or above may not be compatible. Check the charging cable connection.
- Air leakage during connection/disconnection: The air hose uses a thread-type lock system. Some air loss is normal when unthreading. To compensate, you may inflate the tire by an additional 0.5 PSI.
- Hose/Connector gets hot: It is normal for the connector tube and metal terminals to become quite hot during prolonged inflation. Exercise caution when handling after use to avoid burns.
- Bacaan tekanan tidak tepat: Ensure the hose is securely connected to the tire valve. If issues persist, consult the manufacturer for calibration or service.
