With the demand of the luggage market, some creative USB backpacks have become popular.
Adding a USB charging port to the backpack is a good idea.
The backpack itself does not have a charging treasure, but it is designed with a convenient USB port for charging. You can put the charging treasure in the bag, connect the cable well, and pass the external socket, you can charge the package without opening the backpack zipper.
