Nice backpack. I bought it for my daughter as a birthday present, and she loves it. Being able to change pictures and animations from her phone is a big hit. Overall, the build quality is good. It has two laptop/tablet pockets, three external pockets, and a pair of very useful attachment rings. The backpack is well thought out and highly functional.

The only thing to consider is securing the power bank inside. You can place it in the inner pocket, but we decided to sew in a Velcro patch with a quick-release setup. This keeps it from moving around while still making it easy to remove for charging when needed.
