Setup

1. Unpacking: Carefully remove the backpack and all accessories, including the packing cubes and shoe bag, from their packaging.
2. Initial Inspection: Inspect the backpack for any signs of damage or manufacturing defects. Contact customer support if any issues are found.
3. USB Port Preparation: Locate the internal USB cable within the backpack. Connect your personal power bank (not included) to this cable to enable the external charging port.

Operating Instructions

1. Packing: Utilize the included packing cubes to organize your clothing and accessories. Place heavier items closer to your back for better weight distribution.
2. Expanding Capacity: If additional space is needed, locate the expansion zipper around the perimeter of the main compartment and unzip it to increase the backpack's volume.
3. Wearing the Backpack: Adjust the shoulder straps to a comfortable length. Fasten and adjust the chest strap for added stability, especially when carrying heavier loads.
4. Converting to Duffel Bag: To convert the backpack into a carry-on duffel, locate the two buttons under the shoulder straps. Unlock these buttons and tuck the shoulder straps into the dedicated back compartment. This creates a cleaner profile for carrying by hand or checking.

5. Using the USB Charging Port: Once your power bank is connected internally, plug your device's charging cable into the external USB port to charge your device.
6. Attaching to Luggage: Slide the integrated luggage strap over the telescopic handle of your rolling suitcase for secure transport.

Maintenance

• Cleaning: For minor dirt or stains, spot clean the backpack with a damp cloth and mild soap. Do not machine wash, bleach, or tumble dry, as this may damage the material and structural integrity.
• Drying: Allow the backpack to air dry completely in a well-ventilated area, away from direct sunlight or heat sources.
• Storage: When not in use, store the backpack in a cool, dry place to prevent mildew and material degradation.

Troubleshooting

Zipper Malfunction:

If a zipper becomes stiff or difficult to move, apply a small amount of zipper lubricant or wax. Avoid overstuffing the backpack, which can put excessive strain on zippers and lead to breakage.

USB Charging Port Not Working:

Ensure your power bank is fully charged and correctly connected to the internal USB cable. Verify that your device's charging cable is functioning properly. The USB port is a pass-through and does not store power itself.

Backpack Feels Uncomfortable:

Adjust the shoulder straps and chest strap to evenly distribute weight. Ensure the backpack is not overloaded beyond its intended capacity. Utilize the ventilated padding for optimal comfort.
