Maintenance
- Cleaning: The backpack is made from water-repellent, high-density polyester. For general cleaning, wipe with a damp cloth and mild soap. Do not machine wash or tumble dry.

- Zippers: Periodically check zippers for smooth operation. If a zipper becomes stiff, apply a small amount of zipper lubricant or wax.
- Storage: Store the backpack in a cool, dry place away from direct sunlight when not in use.
Troubleshooting
- USB Charging Port Not Working:
- Ensure your portable charger (power bank) is fully charged and correctly connected to the internal USB cable.
- Verify that your device's charging cable is securely plugged into the external USB port.
- Zipper Sticking:
