Though I have come across several different types of backpacks but this one seems something really handy for its cool features and dual functionality:
Built-in batteries for recharging.
Connected mobile application that provides stats on battery percentage and alerts you.
TSA-friendly laptop compartment.
Shoulder-strap holster that keeps your smartphone handy while it recharges.
There is no con for this hunt except that of price that I assume would be high but even if it's bit high, I'd like to give this hunt 5 stars.
