Laptop Backpack for 15.6-17.3 Inch Laptop Anti-Theft Large Computer Backpack with USB Charging Port Water-Repellent $22.39

Decent looking backpack at a reasonable price. It has a USB port to charge your items but power bank not included. Just wanted to point that out.
Water proof and good amount of compartments. Use 9QI3S4HA to drop the price a bit.
