A Phone Charger

Portable Charger

Seriously, with all these photos you're taking your phone is going from fully charged to barely hanging on to 1%. You never want to be out late with a dead phone, so bring a charger with you. Even better if you have a portable one, so you don't have to creepily scour the walls for an outlet.

Ban.do, $35
