How do I use the USB charging feature on my LOVEVOOK 161331M backpack?

[Tyra]

The LOVEVOOK 161331M Waterproof Anti-theft Laptop Backpack is designed for convenient device charging on the go. To utilize the external USB charging port, you'll need a power bank. Here's a simple guide:

1. Make sure your power bank is fully charged and compatible with the backpack's USB port.
2. Locate the external USB port on your LOVEVOOK backpack. It's typically found on the side or front.
3. Open the backpack and find the internal USB cable.
4. Connect one end of the internal USB cable to your power bank's USB output port.
5. Plug the other end of the internal USB cable into the USB port on the exterior of the backpack.
6. Now, connect your phone or other device's charging cable to the external USB port on the backpack.

Your device should begin charging. The charging speed depends on your power bank's specifications and the device being charged. Remember, the LOVEVOOK 161331M backpack itself doesn't provide power; you must supply your own power bank.
