one #goBags tip i have is to get some of #Waterfield (aka #sfbags) gear pouches or #bellroy's fantastic zipper tech valets. you can put a large capacity 29000mAh+ power bank, some a-to-c c-to-c a-to-mini|micro #usb and room for adapters and wall chargers too. zip the little guy together and toss in your bag. i have two and i pull one when i am taking a trip that doesn't involve fleeing the country.
again, bellroy is a #bcorp and you'll love their gear.
