Review on Backpack Waterproof Backpacks Notebook Charging by William Gildea

Pretty decent size. It looks quite small in the picture. But that's not so little. It would be nice to travel. It's waterproof. And there's a pretty decent amount of storage space. But you need a power bank for your backpack so you can charge your phone on the go. I didn't know about it until I ordered a backpack and it was here. The power bank usually costs around $20, but the backpack is not included. So if you still want to charge your phone on the go, buy an external battery.
